asp.net-ajax使用-WebMethod使用

1、js

$.ajax({
            type: "POST",
            contentType: "application/json",
            url: "activity-apply.aspx/BaoMing",
            data: "{ID:1}",
            dataType: 'json',
            success: function (result) {
                $(result.d).each(function () {
                 var datax=this['NeiRong'];
                           
                     if (datax == "报名成功！") {
                         $(".touming,.baoming-success").show();
                         $("html").css("overflow-y", "hidden");
                     } else {
                         alert(datax);
                     }
                });
            },
            error: function (result, e) {
                alert(e);
            }
        });

2、C#，必须为static方法，使用不了跳转

　　session使用方式：HttpContext.Current.Session

 [WebMethod]
        public static string GetAwards()
        {
            if (LotterySets.Count > 0)
            {
                return JsonConvert.SerializeObject(new { Success = true, Data = LotterySets, Msg = "获取成功" });
            }
            else
            {
                return JsonConvert.SerializeObject(new { Success = false, Data = LotterySets, Msg = "奖项为空" });
            }

        }
