全部代码

对一个集合，要求不序列化完，对其中的几项序列化。这时内置序列化对象就不方便。这是用LitJson[“key”]=value；方便。

List<RechargeM> list = RecBL.GetTB(Gid);
foreach (var item in list)
{
JsonData jd = new JsonData();
jd["ID"] = Tools.GetString(item.Id);
jd["Num"] = item.cRech_Num;
jd["Money"] = item.mRech_Money;
jd["Date"] = Tools.GetString(item.dRech_Date);
row.Add(jd);
}
Jlist["RechargeLis"] = row;
