//添加一个 AjaxPro.HttpSessionStateRequirement 枚举的值到你的 AjaxPro.AjaxMethodAttribute中.
//例如：
//[AjaxPro.AjaxMethod(AjaxPro.HttpSessionStateRequirement.Read)]
//现在你就可以像下面这样存取Session的值了: this.Session["0"].ToString().
//另外一个问题：如何在AjaxMethod中使用Cookie?
//答案是不能使用"this"的引用存取cookie ，你必须使用HttpContext.Current
//例如:
//HttpContext.Current.Request.Cookies[Name].Value.
