ASP.NET 註冊Cookie的方法

範例如下

    public string mainMenu(string sKey){
        string sRelust = "";
        if (Request.QueryString["main"] == sKey)
        {
           sRelust = "class=\"active\"";
        }
        return sRelust;
    }

    public string subMenu(string sKey)
    {
        string sRelust = "";
        if (Request.QueryString["sub"] == sKey)
        {
            sRelust = "class=\"current\"";
            AddCookie("menu", "sub", sKey);
        }

        return sRelust;
    }


    public void AddCookie(string sName, string sKey, string sValue)
    {
        //註冊Cookie
        //產生一個Cookie
        HttpCookie cookie = new HttpCookie(sName);
        //設定單值
        cookie.Values.Add(sKey, sValue);
        //設定過期日
        cookie.Expires = DateTime.Now.AddDays(1);
        //寫到用戶端

        Response.Cookies.Add(cookie);    
    }
