        HttpCookie _userInfoCookies = new HttpCookie("UserInfo");

        _userInfoCookies["UserName"] = "Abhijit";
        _userInfoCookies["UserColor"] = "Red";
        _userInfoCookies["Expire"] = "5 Days";  
        
        //Adding Expire Time of cookies
         _userInfoCookies.Expires = DateTime.Now.AddDays(5); //这里是关键
        
        //Adding cookies to current web response 

Response.Cookies.Add(_userInfoCookies);

  HttpCookie _userInfoCookies = new HttpCookie("UserInfo");
        //Adding Expire Time of cookies before existing cookies time
        _userInfoCookies.Expires = DateTime.Now.AddDays(-1);
        //Adding cookies to current web response 

Response.Cookies.Add(_userInfoCookies);
