定义public static str method();
使用 SystemComputed::retunField()定义str值，再使用SystemComputed其他方法构建出Query语句并return就好。

SysDictEnum dictEnum = new SysDictEnum( enumnum(InventTransType) );
dictEnum.value2Label(InventTrans.TransType);

    JObject             jObj;
    JArray              dataJArray = new Newtonsoft.Json.Linq.JArray();

    jObj  = new JObject();

    jObj.Add("code", ecoResCategory.code);
    jObj.Add("name", ecoResCategory.Name);
    dataJArray.Add(jObj);

    keyinfo = int642Str( ecoResCategory.RecId );
    return strReplace(DataJArray.ToString(), "\r\n", "");

Query选框

编写queryRun方法，

public QueryRun queryRun()
{
    QueryRun ret;

    ret = New Query(queryStr(QueryName));

    return ret;
}
