Retrieve e-mail address from Active Directory

[Guest]

Can someone give me C# code that will connect me to Active Directory, let me give Active Directory a user's name and retrieve his/her e-mail address. I need this for a WebForm.

This code should get you the user's full name.
With a little tinkering I bet you can also get the email address.
(also set <identity impersonate="true"/> in your web.config)

string Domain_Slash_User = Context.User.Identity.Name;
Domain_Slash_Machine = Domain_Slash_Machine.Replace(@"\",
@"/");
string queryString = @"WinNT://" + Domain_Slash_Machine;

DirectoryEntry obDirEntry = new DirectoryEntry
(queryString);
System.DirectoryServices.PropertyCollection coll =
obDirEntry.Properties;

object obVal = coll["FullName"].Value;
_User = obVal.ToString();

Session.Add("UserFullName", _User);
