How to get username without domain

Question

In an aspx page I get the Windows username with the function Request.LogonUserIdentity.Name. This function returns a string in the format \"domain\\user\".

Answer 1

If you are using .NET 3.5 you could always create an extension method to the WindowsIdentity class that does this work for you.

public static string NameWithoutDomain( this WindowsIdentity identity )
{
    string[] parts = identity.Name.Split(new char[] { '\\' });

    //highly recommend checking parts array for validity here 
    //prior to dereferencing

    return parts[1];
}

that way all you have to do anywhere in your code is reference:

Request.LogonUserIdentity.NameWithoutDomain();
