推荐答案

使用 Request.Cookies 和 Response.Cookies 处理您的情况.一旦从第三方授权回来的用户创建cookie并将其存储在浏览器中，并且一旦用户注销清除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);   
}
