SPContext.Current.Web.CurrentUser returns misleading value

Question

I\'m trying to find out current user name for my sharepoint application. There are more that one way how to do this. However the sharepoint way returns misleading value.

Answer 1

The problem is because you are probably getting the current user from an elevated SPWeb inside a RunWithElevatedPrivileges code. You can use the snippet below to get the real user

SPWeb site = SPContext.Current.Web;
SPSecurity.RunWithElevatedPrivileges(delegate()
{
    using (SPSite ElevatedsiteColl = new SPSite(siteColl.ID))
   {
       using (SPWeb ElevatedSite = ElevatedsiteColl.OpenWeb(site.ID))
       {
            string currUser = site.CurrentUser; //not the ElevatedSite.CurrentUser
       }
   }
});

This will show the real user name instead of the SHAREPOINT\System user.
