ASP.NET Controller Base Class User.Identity.Name

Question

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).

However, I noticed that in this abstract base class the User property is always null . What do I have to do to get this working?

Thanks a lot

Answer 1

As Paco suggested, the viewdata isn't initialized till after you are trying to use it.

Try overriding Controller.Initialize() instead:

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;
    }
}

Answer 2

要使用该用户，您应该从中获取当前页面

HttpContext.Current.User.Identity.Name

Answer 3

通过在web.config中将身份验证设置为Windows，您可以使用User.Identity.Name获取用户

Answer 4

I use Page class on my static Utlilites classes. Like that;

Page P = (Page)HttpContext.Current.Handler;

and i can get all properties via the P object for the current requested page..

你试过这个：ControllerContext.HttpContext.Current.User.Identity.Name？
