如何在asp.net c＃

中从浏览器中删除cookie

Answer 1

这是怎么做的。

if (Request.Cookies["MyCookie"] != null)
{
    HttpCookie myCookie = new HttpCookie("MyCookie");
    myCookie.Expires = DateTime.Now.AddDays(-1d);
    Response.Cookies.Add(myCookie);
}

Answer 2

以下是您可以删除所有Cookie的代码：

void Page_Load()
    {
        string[] cookies = Request.Cookies.AllKeys;
        foreach (string cookie in cookies)
        {
            BulletedList1.Items.Add("Deleting " + cookie);
            Response.Cookies[cookie].Expires = DateTime.Now.AddDays(-1);
        }
    }

Answer 3

基于http://msdn.microsoft.com/en-us/library/ms178195.aspx的助手：

public static void DeleteCookie(
  HttpRequest request, HttpResponse response, string name)
{
  if (request.Cookies[name] == null) return;
  var cookie = new HttpCookie(name) {Expires = DateTime.Now.AddDays(-1d)};
  response.Cookies.Add(cookie);
}

Answer 4

删除Cookie的最简单方法是将过期日期设置为过去的时间例如，
Set-Cookie: cookieName=; expires=Wed, 12 May 2010 06:33:04 GMT;
它有效，因为在我发布时，Wed, 12 May 2010 06:33:04 GMT是http时间戳，它永远不会再发生。
