H3BPM中前端發送JS對象請求后端C#

BPM流程中用到異步請求, 工作記錄

　　　　　　　//前端定義對象,最后轉成字符串, 發送到C#的接口
            var num=$.MvcSheetUI.GetElement("OTC09_01").SheetGridView().RowCount; //子表行數
            var jsonobj = {}; //定義JSON
            jsonobj.rows=[];  //定義成員數組
            for(var i=1;i<=num;i++)
            {
                var obj={}; //定義數組成員
                obj.qty=$.MvcSheetUI.GetControlValue("OTC09_01.BGSL",i);
                obj.predate=$.MvcSheetUI.GetControlValue("OTC09_01.BGRQ",i);
                obj.socode=$.MvcSheetUI.GetControlValue("OTC09_01.DDH",i);
                obj.rowno=$.MvcSheetUI.GetControlValue("OTC09_01.RowNo",i);
                jsonobj.rows.push(obj);  //把成員加入數組
            }
            $.MvcSheetUI.SetControlValue("jsonobj",JSON.stringify(jsonobj));   //以JSON格式轉成字符串

C#接收到解析
