推荐答案

Response.Cookies.Clear()使用此实现从响应中清除所有cookie.

Response.Cookies.Clear() use this implementation to clear all the cookies from the response.

信不信由你，Response.Cookies.Clear() 不是从Response删除cookie的可靠方法.为了可靠地从浏览器中删除cookie，您需要按照以下步骤设置cookie的到期时间:

Believe it or not, Response.Cookies.Clear() is not a reliable way to remove cookie from the Response. To remove the cookie from browser reliably, you need to set the expiry time of the cookie as follows:

/// <summary>
/// Removes Cookie from the response
/// </summary>
/// <param name="Cookie"></param>
private void RemoveCookie(HttpCookie Cookie)
{
    //Cookie is the current cookie that is to be removed.
    Response.Cookies.Remove(Cookie.Name);
    HttpCookie myCookie = new HttpCookie(Cookie.Name);
    myCookie.Expires = DateTime.Now.AddDays(-1d);
    Response.Cookies.Add(myCookie);
}
