There is more than one way to get the current username using C# or VB.NET i will show you one using Environment Variable and one using the WindowsIdentity.
If you are in a Network the output of both methods is different.
using the Environment variable
Sample C#
string currUsername = Environment.UserName;
Sample VB.NET
Dim currUsername As String = Environment.UserName
using the WindowsIdentity
Sample C#
string currUsername = System.Security.Principal.WindowsIdentity.GetCurrent().Name;
Sample VB.NET
Dim currUsername As String = System.Security.Principal.WindowsIdentity.GetCurrent().Name
Possible Output

<span class="str">using the WindowsIdentity: <strong>Domainname\Username</strong></span> |
