If you need to get the user from within the controller, use the Userproperty of Controller. If you need it from the view, I would populate what you specifically need in the ViewData, or you could just call User as I think it's a property of ViewPage.
如果您需要从控制器内部获取用户，请使用UserController的属性。如果您认为需要的话，我会填充你特别需要的ViewData，或者你可以只调用用户，因为我认为这是一个性质ViewPage。

I realize this is really old, but I'm just getting started with ASP.NET MVC, so I thought I'd stick my two cents in:
我意识到这真的很旧，但我刚刚开始使用 ASP.NET MVC，所以我想我会花两分钱：
Request.IsAuthenticatedtells you if the user is authenticated.Page.User.Identitygives you the identity of the logged-in user.
Request.IsAuthenticated告诉您用户是否已通过身份验证。Page.User.Identity为您提供登录用户的身份。

I found that Userworks, that is, User.Identity.Nameor User.IsInRole("Administrator").
我发现User有效，即，User.Identity.Name或User.IsInRole("Administrator")。

For what it's worth, in ASP.NET MVC 3 you can just use User which returns the user for the current request.
值得一提的是，在 ASP.NET MVC 3 中，您只需使用 User 即可返回当前请求的用户。

If you are inside your login page, in LoginUser_LoggedIn event for instance, Current.User.Identity.Name will return an empty value, so you have to use yourLoginControlName.UserName property.
如果您在登录页面内，例如在 LoginUser_LoggedIn 事件中，Current.User.Identity.Name 将返回一个空值，因此您必须使用 yourLoginControlName.UserName 属性。
MembershipUser u = Membership.GetUser(LoginUser.UserName);
