How to get current user who's accessing an ASP.NET application?

Question

To get the current logged in user at the system I use this code:

string opl = System.Security.Principal.WindowsIdentity.GetCurrent().Name.ToString(); 

I work on an ASP.NET application where I need this information. So I've put my application on a server and tried the code above, and I get "Network Service" in the string opl. I need to know the current user of the PC who accesses my ASP.NET application.

The quick answer is User = System.Web.HttpContext.Current.User

Ensure your web.config has the following authentication element.

<configuration>     <system.web>         <authentication mode="Windows" />         <authorization>             <deny users="?"/>         </authorization>     </system.web> </configuration>
