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

static class IdentityHelpers
{
    public static string ShortName(this WindowsIdentity Identity)
    {
        if (null != Identity)
        {
            return Identity.Name.Split(new char[] {'\\'})[1];
        }
        return string.Empty;
    }
}

If you include this code, you could then just do something like:

WindowsIdentity a = WindowsIdentity.GetCurrent();
Console.WriteLine(a.ShortName);

Obviously in a web environment, you wouldn't write to the console - just an example...
