You can do something like this
public DateTime Get(string attr, string UserName)
{
DomainConfiguration domainConfig = new DomainConfiguration();
using (new SPMonitoredScope("AD Properties"))
{
using (DirectoryEntry domain = new DirectoryEntry("LDAP://" + domainConfig.DomainName, domainConfig.UserName, domainConfig.Password))
{
//DirectorySearcher searcher = new DirectorySearcher(domain, "(|(objectClass=organizationalUnit)(objectClass=container)(objectClass=builtinDomain)(objectClass=domainDNS))");
DirectorySearcher searcher = new DirectorySearcher(domain);
searcher.PageSize = 1000;
searcher.Filter = "(SAMAccountName='" + UserName + "')";
//searcher.Filter = "(|(objectCategory=group)(objectCategory=person))";
searcher.Filter = "(&(objectClass=user) (cn=" + UserName + "))";
var user = searcher.FindOne();
DateTime LastLogon = DateTime.FromFileTime((Int64)user.Properties["lastLogon"].Value);
return LastLogon;
}
}
}
Hope this Helps you.

I do not know why it does gives me the some older dates than i expected.
but at least it will compile and run.
using System.DirectoryServices.AccountManagement;
private static DateTime? GetUserIdFromDisplayName(string displayName)
{
// set up domain context
using (PrincipalContext ctx = new PrincipalContext(ContextType.Domain))
{
// find user by display name
UserPrincipal user = UserPrincipal.FindByIdentity(ctx, displayName);
if (user != null)
{
return user.LastLogon;
}
else
{
return null;
}
}
}
