Question

我的文件夹Shared中有一个Login.aspx文件。当我单击我的logut按钮时，它会转到SessionController-＆gt; LogOut操作。我有问题。

我的FormsAuthentication未登出。
重定向到Login.aspx时出错：

System.InvalidOperationException：'〜/ Views / Shared / Login.aspx'的视图必须从ViewPage，ViewPage，ViewUserControl或ViewUserControl派生。

我收到了这段代码：

我的控制器：

public class SessionController : Controller
{
    public ActionResult LogOut()
    {
        if (Request.Cookies["Usuario"] != null)
        {
            FormsAuthentication.SignOut();
            var c = new HttpCookie("Usuario");
            c.Expires = DateTime.Now.AddDays(-1);
            Response.Cookies.Add(c);
        }
        return View("Login");
    }
}

我从HTML到de Conttroller的调用：

<ul class="dropdown-menu">
    <li><a id="logout" href="~/Session/LogOut">Log out</a></li>
</ul>

和Login.aspx：

Answer 1

正如异常所说，MVC视图必须继承特定的MVC基础结构类才能被识别为MVC视图。

对于ASPX视图引擎，您需要以明确的方式指定它，例如

<%@ Page Language="C#" 
    Inherits="System.Web.Mvc.ViewPage<YourModelClassName>" %>

或

    Inherits="System.Web.Mvc.ViewPage"

如果您的观点不期望任何模型。

Answer 2

希望这有帮助

return Redirect("url");

或

return RedirectToRoute("routename"); // Specify route in the Route Config file.
