Answer 1

你用什么方法注销的? 还有用什么方法创建cookie的

Answer 2

 HttpCookie cookieObj = new HttpCookie(cookieName);
        cookieObj.Value = cookieValue;
        objRes.Cookies.Add(cookieObj);






  HttpCookie myCookie = new HttpCookie(CookieName);
        DateTime now = DateTime.Now;

        myCookie.Expires = now.AddYears(-2);

        HttpContext.Current.Response.Cookies.Add(myCookie);

Answer 3

  HttpCookie c = Request.Cookies[CookieName];
            Response.Cookies[c.Name].Expires = DateTime.Now.AddYears(-1);

Answer 4

或者可以试试
Response.Cookies.RemoveCookie(FormsCookieName);

那是因为缓存的问题。注销之后，请进行重定向
Response.Redirect("some.aspx");
