    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;
