How to Get the currently logged on user name

I am building a small intranet app in which I need to display the user name of the person who opens the webpage.

I tries with:

WindowsIdentity.GetCurrent().Name.ToString();

But this always displays my user name on the webpage.

use this code 

if (User.Identity.IsAuthenticated)
 Label1.Text = User.Identity.Name;
else
 Label1.Text = "No user identity available.";

look at the following article Forms Authentication in ASP.NET

Please see THIS - basicaly you need to enable Integrated windows authentication and the use one of the following:

System.Security.Principal.WindowsPrincipal p = System.Threading.Thread.CurrentPrincipal as System.Security.Principal.WindowsPrincipal;    
string strName = p.Identity.Name;

or

string strName = HttpContext.Current.User.Identity.Name.ToString();

or

string strName = Request.ServerVariables["AUTH_USER"]; //Finding with name    
string strName = Request.ServerVariables[5]; //Finding with index

All 3 cases should retrun a string containing DomainName\WinNTLoggedUserName.

See http://forums.asp.net/t/1102996.aspx/1. I think the reason that you see your own name is that the web app is running under your credentials.

So use HttpContext.Current.User.Identity.Name instead and make sure that you have enabled Forms authentication in web.config

You can use this:

Page.User.Identity.Name

P.S: Don't forget to check entities whether they were null first.
