ASP.NET Controller Base Class User.Identity.Name
提问by Masterfu
As described in this post, I created an abstract base controller class in order to be able to pass data from a controller to master.page. In this case, I want to lookup a user in my db, querying for User.Identity.Name (only if he is logged in).
如在描述的这篇文章中，我创建一个抽象基类控制器，以便能够从控制器的数据传递到master.page。在这种情况下，我想在我的数据库中查找用户，查询 User.Identity.Name（仅当他登录时）。
However, I noticed that in this abstract base class the Userproperty is always null. What do I have to do to get this working?
但是，我注意到在这个抽象基类中，User属性总是null. 我该怎么做才能让它发挥作用？
Thanks a lot
非常感谢

我在静态 Utlilites 类上使用 Page 类。像那样;
Page P = (Page)HttpContext.Current.Handler;
页面 P = (Page)HttpContext.Current.Handler;
and i can get all properties via the P object for the current requested page..
我可以通过 P 对象获取当前请求页面的所有属性。

As Paco suggested, the viewdata isn't initialized till after you are trying to use it.
正如 Paco 所建议的，viewdata 在您尝试使用它之前不会初始化。
Try overriding Controller.Initialize() instead:
尝试覆盖 Controller.Initialize() 代替：
public abstract class ApplicationController : Controller
{
private IUserRepository _repUser;
public ApplicationController()
{
}
protected override void Initialize(System.Web.Routing.RequestContext requestContext)
{
base.Initialize(requestContext);
_repUser = RepositoryFactory.getUserRepository();
var loggedInUser = _repUser.FindById(User.Identity.Name);
ViewData["LoggedInUser"] = loggedInUser;
}
}
