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

I don't believe so. I have got the username using these methods before-

var user = System.Web.HttpContext.Current.User;   
var name = user.Identity.Name;

var slashIndex = name.IndexOf("\\");
return slashIndex > -1 
    ? name.Substring(slashIndex  + 1)
    : name.Substring(0, name.IndexOf("@"));

or

var name = Request.LogonUserIdentity.Name;

var slashIndex = name.IndexOf("\\");
return slashIndex > -1 
    ? name.Substring(slashIndex  + 1)
    : name.Substring(0, name.IndexOf("@"));
