System.Web.UI.Page won't let me access CurrentUser or User.Identity from a Controller in ASP.Net-MVC

Question

When I try

user = System.Web.UI.Page.CurrentUser

or

user = System.Web.UI.Page.User.Identity

I get an erro

Answer 1

There are many ways to do it (basically, they are all the same)

User.Identity // in the controller
HttpContext.User.Identity // in the controller
System.Web.HttpContext.Current.User.Identity // anywhere

Page.User property works when there's a Page HTTP handler that's processing the current request. As in an MVC controller, the request has not been handed to a Page class, it won't work.

in the controller.
