I have used the below code to send the mail notifications using the C# code
public static void SendNotification(string filepath)
{
try
{
SmtpClient mailServer = new SmtpClient(ConfigurationManager.AppSettings["host"], int.Parse(ConfigurationManager.AppSettings["portnumber"]));
mailServer.EnableSsl = true;
mailServer.Credentials = new System.Net.NetworkCredential(ConfigurationManager.AppSettings["sender_username"], ConfigurationManager.AppSettings["sender_password"]);
string from = ConfigurationManager.AppSettings["sender"];
string to = ConfigurationManager.AppSettings["receipients"];
string cc = ConfigurationManager.AppSettings["receipientCC"];
MailMessage msg = new MailMessage(from, to);
msg.Subject = "Branch API Export Results";
msg.Body = "Test Mail. Please Find Attached for the Results from Branch API Export";
msg.CC.Add(cc);
msg.Attachments.Add(new Attachment(filepath));
mailServer.Send(msg);
}
catch (Exception ex)
{
//Log
}
}
Included the configuration values in the App.Config. Any better way other than this.
Here is.
private static void SendMail(string subject, string content)
{
try
{
MailMessage mail = new MailMessage();
SmtpClient SmtpServer = new SmtpClient("smtp.gmail.com");
mail.From = new MailAddress("YOURMAİL");
mail.To.Add("MAİLTO");
mail.Subject = subject;
mail.Body = content;
SmtpServer.Port = 25;
SmtpServer.Credentials = new System.Net.NetworkCredential("YOURMAİL", "YOURMAİLPASSWORD");
SmtpServer.EnableSsl = true;
SmtpServer.Send(mail);
}
catch (Exception ex)
{
}
}
This is simplest way to send mail. Don't forget to add using System.Net.Mail;

I have a Notification Service Extension and an AppGroup. I save a photo from camera in the PCL project and copy it to the App Group Container (shared folder).
In the Notification Service Extension I try to download the photo from the App Group container and attach it to the notification but it just does not display in the notification.
I also cannot debug the Service Extension to see what is going. As far as I know that is not possible currently still in Xamarin unless someone can correct me on that please.
Here is the code:
1.in my PCL I save the photo to the AppGroup when a save button is pressed:
private void ButtonSavePhoto_Clicked(object sender, EventArgs e)
{
if (!string.IsNullOrEmpty(photoFilePath))
{
Preferences.Set(AppConstants.CUSTOM_PICTURE_FILE_PATH, photoFilePath);
Preferences.Set(AppConstants.CUSTOM_PHOTO_SET_KEY, true);
if (Device.RuntimePlatform == Device.iOS)
{
bool copiedSuccessfully = DependencyService.Get<IPhotoService>().CopiedFileToAppGroupContainer(photoFilePath);
if (copiedSuccessfully)
{
var customPhotoDestPath = DependencyService.Get<IPhotoService>().GetAppContainerCustomPhotoFilePath();
// save the path of the custom photo in the AppGroup container to pass to Notif Extension Service
DependencyService.Get<IGroupUserPrefs>().SetStringValueForKey("imageAbsoluteString", customPhotoDestPath);
// condition whether to use custom photo in push notification
DependencyService.Get<IGroupUserPrefs>().SetBoolValueForKey("isCustomPhotoSet", true);
}
}
buttonSavePhoto.IsEnabled = false;
}
}
2.in my iOS project, Dependency injection calls this method when pressing save button:
public bool CopiedFileToAppGroupContainer(string filePath)
{
bool success = false;
string suiteName = "group.com.company.appName";
var appGroupContainerUrl = NSFileManager.DefaultManager.GetContainerUrl(suiteName);
var appGroupContainerPath = appGroupContainerUrl.Path;
var directoryNameInAppGroupContainer = Path.Combine(appGroupContainerPath, "Pictures");
var filenameDestPath = Path.Combine(directoryNameInAppGroupContainer, AppConstants.CUSTOM_PHOTO_FILENAME);
try
{
Directory.CreateDirectory(directoryNameInAppGroupContainer);
if (File.Exists(filenameDestPath))
{
File.Delete(filenameDestPath);
}
File.Copy(filePath, filenameDestPath);
success = true;
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
}
return success;
}
Now the path for the photo in the App Group container is:
/private/var/mobile/Containers/Shared/AppGroup/12F209B9-05E9-470C-9C9F-AA959D940302/Pictures/customphoto.jpg
3.Finally in the Notification Service Extension I try to attach the photo to the push notification:
public override void DidReceiveNotificationRequest(UNNotificationRequest request, Action<UNNotificationContent> contentHandler)
{
ContentHandler = contentHandler;
BestAttemptContent = (UNMutableNotificationContent)request.Content.MutableCopy();
string imgPath;
NSUrl imgUrl;
string notificationBody = BestAttemptContent.Body;
string notifBodyInfo = "unknown";
string suiteName = "group.com.company.appname";
NSUserDefaults groupUserDefaults = new NSUserDefaults(suiteName, NSUserDefaultsType.SuiteName);
string pref1_value = groupUserDefaults.StringForKey("user_preference1");
string[] notificationBodySplitAtDelimiterArray = notificationBody.Split(',');
userPrefRegion = notificationBodySplitAtDelimiterArray[0];
bool isCustomAlertSet = groupUserDefaults.BoolForKey("isCustomAlert");
bool isCustomPhotoSet = groupUserDefaults.BoolForKey("isCustomPhotoSet");
string alarmPath = isCustomAlertSet == true ? "customalert.wav" : "default_alert.m4a";
if (isCustomPhotoSet)
{
// this is the App Group url of the custom photo saved in PCL
imgPath = groupUserDefaults.StringForKey("imageAbsoluteString");
}
else
{
imgPath = null;
}
if (imgPath != null )
{
imgUrl = NSUrl.FromString(imgPath);
}
else
{
imgUrl = null;
}
if (!string.IsNullOrEmpty(pref1_value))
{
if (BestAttemptContent.Body.Contains(pref1_value))
{
if (imgUrl != null)
{
// download the image from the AppGroup Container
var task = NSUrlSession.SharedSession.CreateDownloadTask(imgUrl, (tempFile, response, error) =>
{
if (error != null)
{
ContentHandler(BestAttemptContent);
return;
}
if (tempFile == null)
{
ContentHandler(BestAttemptContent);
return;
}
var cache = NSSearchPath.GetDirectories(NSSearchPathDirectory.CachesDirectory, NSSearchPathDomain.User, true);
var cachesFolder = cache[0];
var guid = NSProcessInfo.ProcessInfo.GloballyUniqueString;
var fileName = guid + "customphoto.jpg";
var cacheFile = cachesFolder + fileName;
var attachmentUrl = NSUrl.CreateFileUrl(cacheFile, false, null);
NSError err = null;
NSFileManager.DefaultManager.Copy(tempFile, attachmentUrl, out err);
if (err != null)
{
ContentHandler(BestAttemptContent);
return;
}
UNNotificationAttachmentOptions options = null;
var attachment = UNNotificationAttachment.FromIdentifier("image", attachmentUrl, options, out err);
if (attachment != null)
{
BestAttemptContent.Attachments = new UNNotificationAttachment[] { attachment };
}
});
task.Resume();
}
BestAttemptContent.Title = "My Custom Title";
BestAttemptContent.Subtitle = "My Custom Subtitle";
BestAttemptContent.Body = "Notification Body";
BestAttemptContent.Sound = UNNotificationSound.GetSound(alarmPath);
}
}
else
{
pref1_value = "error getting extracting user pref";
}
// finally display customized notification
ContentHandler(BestAttemptContent);
}
/private/var/mobile/Containers/Shared/AppGroup/12F209B9-05E9-470C-9C9F-AA959D940302/Pictures/customphoto.jpg
From shared code, when image getting from AppGroup .You can check the file path whether work in this project.
imgPath = groupUserDefaults.StringForKey("imageAbsoluteString");
If not getting file from this path. You can get Url from AppGroup directly.Here is a sample as follow:
var FileManager = new NSFileManager();
var appGroupContainer = FileManager.GetContainerUrl("group.com.company.appName");
NSUrl fileURL = appGroupContainer.Append("customphoto.jpg", false);
And if fileURL can not be directly used, also can convert to NSData and save to local file system. This also can be a try.
Here is a sample below that grabs from local file system:
public static void Sendlocalnotification()
{
var localURL = "...";
NSUrl url = NSUrl.FromString(localURL) ;
var attachmentID = "image";
var options = new UNNotificationAttachmentOptions();
NSError error;
var attachment = UNNotificationAttachment.FromIdentifier(attachmentID, url, options,out error);
var content = new UNMutableNotificationContent();
content.Attachments = new UNNotificationAttachment[] { attachment };
content.Title = "Good Morning ~";
content.Subtitle = "Pull this notification ";
content.Body = "reply some message-BY Ann";
content.CategoryIdentifier = "message";
var trigger1 = UNTimeIntervalNotificationTrigger.CreateTrigger(0.1, false);
var requestID = "messageRequest";
var request = UNNotificationRequest.FromIdentifier(requestID, content, trigger1);
UNUserNotificationCenter.Current.AddNotificationRequest(request, (err) =>
{
if (err != null)
{
Console.Write("Notification Error");
}
});
}
I have implemented something similar to the following question and I can get it working locally on my server, but when I deploy to Azure it doesn't work. I don't get any errors: just an email without the attachment.
Sending attachments using Azure blobs
Are there restrictions on what types of files can be sent with SendGrid (file is only 56k)?
Does the Azure App service have to be at a particular level or can it be done on Basic?
The blob URL definitley exists and I am setting the stream to zero as suggested in that previous question.
MailMessage mm = new MailMessage("receiver address", "someone");
mm.From = new MailAddress("myAddress", "My Name");
mm.Subject = content.Subject;
mm.Body = content.Body;
mm.IsBodyHtml = true;
mm.BodyEncoding = UTF8Encoding.UTF8;
mm.DeliveryNotificationOptions = DeliveryNotificationOptions.OnFailure;
var attachmentAsStream = _storageAccessService.GetAssetAsStreamForEmail("myContainer", "fileThatExists.pdf");
var attachment = new Attachment(attachmentAsStream, "File.pdf", MediaTypeNames.Application.Pdf);
mm.Attachments.Add(attachment);
public MemoryStream GetAssetAsStreamForEmail(string containerName, string fileName)
{
// Create the blob client.
CloudBlobClient blobClient = StorageAccountReference().CreateCloudBlobClient();
// Retrieve reference to a previously created container.
CloudBlobContainer container = blobClient.GetContainerReference(containerName);
CloudBlockBlob blob = container.GetBlockBlobReference(fileName);
var memoryStream = new MemoryStream();
try
{
using (var stream = new MemoryStream())
{
blob.DownloadToStream(memoryStream);
memoryStream.Seek(0, SeekOrigin.Begin);
}
}
catch (Exception ex)
{
Elmah.ErrorSignal.FromCurrentContext().Raise(new Exception("Failed to download Email Atatchment: "+ ex.Message));
}
memoryStream.Position = 0;
return memoryStream;
}
using (SmtpClient client = new SmtpClient())
{
client.Port = 587;
client.Host = "smtp.sendgrid.net";
client.EnableSsl = true;
client.Timeout = 10000;
client.DeliveryMethod = SmtpDeliveryMethod.Network;
client.UseDefaultCredentials = false;
client.Credentials = new System.Net.NetworkCredential("hidden", "hidden");
await client.SendMailAsync(message);
}
Update
Update after Yasir's suggestion below. Downloading the blob from Azure as a Stream only seems to work locally. But if I change to download as a ByteArray then it works everywhere, nonetheless...
public MemoryStream GetAssetAsStreamForEmail(string containerName, string fileName)
{
// Create the blob client.
CloudBlobClient blobClient = StorageAccountReference().CreateCloudBlobClient();
// Retrieve reference to a previously created container.
CloudBlobContainer container = blobClient.GetContainerReference(containerName);
CloudBlockBlob blob = container.GetBlockBlobReference(fileName);
try
{
blob.FetchAttributes();
var fileStream = new byte[blob.Properties.Length];
for (int i = 0; i < blob.Properties.Length; i++)
{
fileStream[i] = 0x20;
}
blob.DownloadToByteArray(fileStream, 0) ;
MemoryStream bufferStream = new MemoryStream(fileStream);
}
catch (Exception ex)
{
Elmah.ErrorSignal.FromCurrentContext().Raise(new Exception("Failed to download Email Atatchment: " + ex.Message));
}
return null;
}
The following code works for me for sending emails using Sendgrid from Azure functions. I attach a CSV file from Blob Storage. It should work for you as well. All you will have to do is ensure that you read the pdf file as a byte[].
public interface IEmailAttachment
{
string Name { get; }
byte[] FileData { get; }
}
public static void Send(MailMessage mailMessage, IEnumerable<IEmailAttachment> attachments)
{
try
{
// Get the configuration data
string server = ConfigReader.EmailServer;
int port = ConfigReader.EmailPort;
string username = ConfigReader.SendGridUserName;
string password = ConfigReader.SendGridPassword;
smtpClient.EnableSsl = false;
smtpClient.Credentials = new NetworkCredential(username, password);
// Create the SMTP Client
SmtpClient smtpClient = new SmtpClient(server, port);
// Prepare the MailMessage
mailMessage.From = new MailAddress(ConfigReader.FromEmail);
var toEmails = ConfigReader.ToEmail.Split(',');
foreach (var toEmail in toEmails)
{
mailMessage.To.Add(toEmail);
}
var ccEmails = ConfigReader.EmailCc.Split(',');
foreach (var ccEmail in ccEmails)
{
mailMessage.CC.Add(ccEmail);
}
// Add attachments
List<MemoryStream> files = new List<MemoryStream>();
if (attachments != null)
{
foreach (IEmailAttachment file in attachments)
{
MemoryStream bufferStream = new MemoryStream(file.FileData);
files.Add(bufferStream);
Attachment attachment = new Attachment(bufferStream, file.Name);
mailMessage.Attachments.Add(attachment);
}
}
mailMessage.IsBodyHtml = true;
// Send the email
smtpClient.Send(mailMessage);
foreach (MemoryStream stream in files)
{
stream.Dispose();
}
}
catch (Exception)
{
throw;
}
}
So, first time attempting to send mail from a mvc application and lo and behold, it didn't work :(
Here's the spaghetti I've whipped up so far from some sources, needless to say I end up in the Error View:
[HttpPost]
public ActionResult Contact(Contact c)
{
if (ModelState.IsValid)
{
try
{
MailMessage msg = new MailMessage();
SmtpClient smtp = new SmtpClient();
MailAddress from = new MailAddress(c.Email.ToString());
StringBuilder sb = new StringBuilder();
msg.To.Add("myaddress#mail.com");
msg.Subject = "New Message";
msg.IsBodyHtml = false;
smtp.Host = "smtp.gmail.com";
smtp.Port = 587;
smtp.EnableSsl = true;
smtp.DeliveryMethod = SmtpDeliveryMethod.Network;
smtp.Credentials = new System.Net.NetworkCredential("myaddress#mail.com", "mypassword");
sb.Append("Name: " + c.Name);
sb.Append(Environment.NewLine);
sb.Append("Email: " + c.Email);
sb.Append(Environment.NewLine);
sb.Append("Message: " + c.Message);
msg.Body = sb.ToString();
smtp.Send(msg);
msg.Dispose();
return View();
}
catch (Exception)
{
return View("Error");
}
}
return View();
}
We are trying to use the O365 Unified API to send emails from our line-of-business apps. I use the following code to send the email. This throws a DataServiceQueryException exception "Unauthorized".
public async Task SendEmailAsUserAsync(EmailMessage message)
{
try
{
var graphClient = await _authenticationHelper.GetGraphClientAsync();
Message m = InitializeMessage(message);
await graphClient.Me.SendMailAsync(m, true);
}
catch (DataServiceQueryException dsqe)
{
_logger.Error("Could not get files: " + dsqe.InnerException.Message, dsqe);
throw;
}
}
private static Message InitializeMessage(EmailMessage message)
{
ItemBody body = new ItemBody {Content = message.Body, ContentType = BodyType.HTML};
Message m = new Message
{
Body = body,
Subject = message.Subject,
Importance = Importance.Normal,
};
//Add all the to email ids
if (message.ToRecipients != null)
foreach (Models.Messaging.EmailAddress emailAddress in message.ToRecipients)
{
m.ToRecipients.Add(new Recipient { EmailAddress = new Microsoft.Graph.EmailAddress { Address = emailAddress.Address, Name = emailAddress.Name } });
}
return m;
}
The code for _authenticationHelper.GetGraphClientAsync() is
public async Task<GraphService> GetGraphClientAsync()
{
Uri serviceRoot = new Uri(appConfig.GraphResourceUriBeta + appConfig.Tenant);
_graphClient = new GraphService(serviceRoot,
async () => await AcquireTokenAsyncForUser(appConfig.GraphResourceUri, appConfig.Tenant));
return _graphClient;
}
private async Task<string> AcquireTokenAsyncForUser(string resource, string tenantId)
{
AuthenticationResult authenticationResult = await GetAccessToken(resource, tenantId);
_accessCode = authenticationResult.AccessToken;
return _accessCode;
}
private async Task<AuthenticationResult> GetAccessToken(string resource, string tenantId)
{
string authority = appConfig.Authority;
AuthenticationContext authenticationContext = new AuthenticationContext(authority);
ClientCredential credential = new ClientCredential(appConfig.ClientId, appConfig.ClientSecret);
string authHeader = HttpContext.Current.Request.Headers["Authorization"];
string userAccessToken = authHeader.Substring(authHeader.LastIndexOf(' ')).Trim();
UserAssertion userAssertion = new UserAssertion(userAccessToken);
var authenticationResult = await authenticationContext.AcquireTokenAsync(resource, credential, userAssertion);
return authenticationResult;
}
However if I change the SendEmailAsUserAsync method as shown below, the email is sent but an InvalidOperationException is thrown with message "The complex type 'System.Object' has no settable properties."
public async Task SendEmailAsUserAsync(EmailMessage message)
{
try
{
var graphClient = await _authenticationHelper.GetGraphClientAsync();
Message m = InitializeMessage(message);
//await graphClient.Me.SendMailAsync(m, true); //This did not work
var user = await graphClient.Me.ExecuteAsync();
await user.SendMailAsync(m, true);
}
catch (DataServiceQueryException dsqe)
{
_logger.Error("Could not get files: " + dsqe.InnerException.Message, dsqe);
throw;
}
}
Can any one point out if there is something wrong here.
Check the example project below, this has a working example (after you fill in the ClientID etc. in app.config).
Office 365 API demo applications
For sending email it uses the function below, which works if you set it up correctly. It also has a number of functions for Authenticating using Authorization Code Grant Flow.
public async Task SendMail(string to, string subject, string body)
{
var client = await this.AuthenticationHelper
.EnsureOutlookServicesClientCreatedAsync(
Office365Capabilities.Mail.ToString());
Message mail = new Message();
mail.ToRecipients.Add(new Recipient()
{
EmailAddress = new EmailAddress
{
Address = to,
}
});
mail.Subject = subject;
mail.Body = new ItemBody() { Content = body, ContentType = BodyType.HTML };
await client.Me.SendMailAsync(mail, true);
}
Actually, there is no assembly wrapper for the graph API.
Microsoft.Graph.dll is deprecrated.
So, you should to :
Deal with the REST requests : See here : http://graph.microsoft.io/docs/api-reference/v1.0/api/message_send
Generate a wrapper with Microsoft.Vipr project : see here : https://github.com/microsoft/vipr
For the authentication, ADAL works fine :)
Using the Google Docs Java API with a Google Apps account, is it possible to impersonate a user and download a file?
When I run the program below, it is clearly logging on to the domain and impersonating the user because it retrieves the details of one of the files and prints out the file title. However, when it tries to download the file, a ServiceForbiddenException is thrown.
If it is not possible with the Java API, does anyone know if it is possible for my program to write an HTTP request to download the file using the Protocol API?

Impersonation will work as intended if you use Oauth2 with ServiceAccounts
