推荐答案

使用 Request.Cookies 和 Response.Cookies 来处理您的情况.一旦用户从第三方授权返回创建 cookie 并将其存储在浏览器中，一旦用户注销清除 cookie.

Use Request.Cookies and Response.Cookies to handle your situation. once user coming back from third party authorization create cookie and store it in browser and once user Logout clear the cookie.

 string cookievalue ;
 if ( Request.Cookies["cookie"] != null )
 {
    cookievalue = Request.Cookies["cookie"].Value.ToString();
 }
 else
 {
    Response.Cookies["cookie"].Value = "cookie value";
 }

要删除 cookie，请使用以下代码

For removing cookie use following code

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