推荐答案

Cookie位于客户端计算机上.
如果用户从客户端结束会话，则可以尝试使用以下javascript.
如果用户只是关闭浏览器，或者浏览器意外关闭，我不确定该事件将触发.
您将无法通过Response的服务器端代码有效地执行此操作，因为这将需要回发，如果用户离开您的页面或关闭其浏览器，则不会发生回发.如果只想在显式注销时删除cookie，则可以使用Prasad的另一个答案(解决方案1)，该答案显示了如何从服务器端进行操作.

Cookies are located on the client machine.
If the user ends their session from the client side you can try using the following javascript.
If the user simply closes their browser, or if the browser closes unexpectedly, I''m not sure the event will fire.
You won''t be able to do this effectively from the server side code from a Response because that would require a postback which does not happen if the user navigates away from your page or closes their browser. If you only want to remove the cookies on explicit sign-out, then you can use the other answer from Prasad(Solution 1) which shows how you can do it from the server side.

window.onbeforeunload = function() {
   var cookies = document.cookie.split(";");
   for (var i = 0; i < cookies.length; i++)
      eraseCookie(cookies[i].split("=")[0]);
};

function createCookie(name,value,days) {
    if (days) {
        var date = new Date();
        date.setTime(date.getTime()+(days*24*60*60*1000));
        var expires = "; expires="+date.toGMTString();
    }
    else var expires = "";
    document.cookie = name+"="+value+expires+"; path=/";
}

function readCookie(name) {
    var nameEQ = name + "=";
    var ca = document.cookie.split(';');
    for(var i=0;i < ca.length;i++) {
        var c = ca[i];
        while (c.charAt(0)==' ') c = c.substring(1,c.length);
        if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length,c.length);
    }
    return null;
}

function eraseCookie(name) {
    createCookie(name,"",-1);
}

代码参考 [

Code Reference[^]

首先看看这个 MSDN [ ^ ]文章.

试试这个:

Firstly have a look on this MSDN[^] article.

Try this:

if (Request.Cookies["userId"] != null)
    {
        Response.Cookies["userId"].Expires = DateTime.Now.AddDays(-1);   
    }

但是使用
也很有意义

But it also makes sense to use

Session.Abandon();
