Azure: Output not as expected in Blob Write - azure

Question

I am trying to write output to a text file stored in my azure container.
Following is my woker role snippet for it :
string copyTemp="";
copyTemp += "hi" + "\n";
copyTemp += "hello" + "\n";
if (String.IsNullOrEmpty(copyTemp))
return;
using (var memoryStream = new MemoryStream())
{
memoryStream.Write(System.Text.Encoding.UTF8.GetBytes(copyTemp), 0, System.Text.Encoding.UTF8.GetBytes(copyTemp).Length);
memoryStream.Position = 0;
blockBlob.UploadFromStream(memoryStream);
}
Now, when i download and check my blob,the output doesn't feature a new line.
"hihello"
Does anyone have an idea,what's goin wrong ?

Answer 1

Have you tried using Environment.NewLine rather than adding "\n" to your strings?
It might just be that your "\n" is not a full new line in the place you are reading it. In windows I believe you need a "\r\n" to get a proper new line character.
You can read about the differences between new line (\n) and carriage return (\r) and which systems use which on Wikipedia but that clarifies h that windows uses a carriage return and a line feed to signify a new line.
So if you had downloaded your blob on a Mac or on Linux it probably would have displayed as you expected.

The best solution for C# is to use the static string property Environment.NewLine. You can use it for writing text content to files, to azure blobs, to console output, and you will never have to think whether it is \n or \r\n. In your case the code will be:
string copyTemp="";
copyTemp += "hi" + Environment.NewLine;
copyTemp += "hello" + Environment.NewLine;
