我在mvc4中注销时如何清除所有会话变量？

Question

我是Asp.Net Mvc4的新手。我想在我退出时清除所有会话变量。我正在使用此代码。但它不起作用。请帮助我得到它。提前谢谢。

我的控制器代码：

public ActionResult Logout()
        {
            System.Web.Security.FormsAuthentication.SignOut();
            Session.Clear();
            Session.RemoveAll();
            return RedirectToAction("Index", "Login");
        }

尝试清除Cookie：

// clear authentication cookie
HttpCookie cookie1 = new HttpCookie(FormsAuthentication.FormsCookieName, "");
cookie1.Expires = DateTime.Now.AddYears(-1);
Response.Cookies.Add(cookie1);

// clear session cookie
HttpCookie cookie2 = new HttpCookie("ASP.NET_SessionId", "");
cookie2.Expires = DateTime.Now.AddYears(-1);
Response.Cookies.Add(cookie2);
