如何删除asp.net中的cookie

// 获取当前响应的Cookie集合
HttpCookieCollection cookies = Response.Cookies;

// 根据Cookie名称获取要删除的Cookie
HttpCookie cookie = cookies["CookieName"];

// 如果Cookie存在，将其过期时间设置为过去的时间
if (cookie != null)
{
    cookie.Expires = DateTime.Now.AddDays(-1);
}

// 获取当前响应的Cookie集合
HttpCookieCollection cookies = Response.Cookies;

// 遍历所有Cookie并将其过期时间设置为过去的时间
foreach (string cookieName in cookies.AllKeys)
{
    HttpCookie cookie = cookies[cookieName];
    if (cookie != null)
    {
        cookie.Expires = DateTime.Now.AddDays(-1);
    }
}
