本文介绍了如何从.Net删除Cookie的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我要用户注销时删除cookie。

I want to delete cookies when the user logout.

这是我的代码：

 if (HttpContext.Current.Request.Cookies["currentUser"] != null)
 {
     DeleteCookie(HttpContext.Current.Request.Cookies["currentUser"]);
 }


       public void DeleteCookie(HttpCookie httpCookie)
        {
            try
            {
                httpCookie.Value = null;
                httpCookie.Expires = DateTime.Now.AddMinutes(-20);
                HttpContext.Current.Request.Cookies.Add(httpCookie);
            }
            catch (Exception ex)
            {
                throw (ex);
            }
        }

但这不起作用。你有什么建议吗？

But it doesn't work. Do you have any suggestion?

推荐答案

 HttpCookie currentUserCookie = HttpContext.Current.Request.Cookies["currentUser"];
 HttpContext.Current.Response.Cookies.Remove("currentUser");
 currentUserCookie.Expires = DateTime.Now.AddDays(-10);
 currentUserCookie.Value = null;
 HttpContext.Current.Response.SetCookie(currentUserCookie);

有效。
