Finding Windows User in .net

Question

I am using Environment.UserName to get the UserName in .net , but Iam getting Machine name instead of UserName. Also I tried using System.Security.Principal.WindowsIdentity.GetCurrent().Name.ToString(); and even this returning Machine name instead of UserName. Any idea?

Try this (found on http://www.developerfusion.com/code/4409/get-current-username-in-vbnet)

Declare Function GetUserName Lib "advapi32.dll" Alias _
       "GetUserNameA" (ByVal lpBuffer As String, _
       ByRef nSize As Integer) As Integer

   Public Function GetUserName() As String
       Dim iReturn As Integer
       Dim userName As String
       userName = New String(CChar(" "), 50)
       iReturn = GetUserName(userName, 50)
       GetUserName = userName.Substring(0, userName.IndexOf(Chr(0)))
   End Function
