Question

我想在每次登录用户切换到主页后执行操作。但我需要切换Binding myBinding = new Binding(); myBinding.Source = win.DataContext; myBinding.Path = new PropertyPath(""); myBinding.Mode = BindingMode.TwoWay; myBinding.UpdateSourceTrigger = UpdateSourceTrigger.PropertyChanged; sampleText.SetBinding(TextBlock.TextProperty, myBinding);。我试着把道路放在路上，但它不起作用。任何的想法？这是我的View/Car/Index：

AccountController

Answer 1

public ActionResult LoggedIn()
    {
        if (Session["UserID"] != null)
        {
            return View();
        }
        else
        {
            return RedirectToAction("Login");
        }

    }

我认为您必须将要显示的视图名称放在＆＃34;返回视图（＆＃34; nameOfViewHere＆＃34;）＆＃34;。

Answer 2

return RedirectToAction("Index", "Car");

从另一个控制器调用时，您也需要传递控制器名称
