后端代码如何取当前主表里面的子表的字段值呢

H3.DataModel.BizObject[]   details = (H3.DataModel.BizObject[])this.Request.BizObject["D00002SalesOrderDetail"]; //获取子表属性并强制转换为对象数组  D00002SalesOrderDetail改成子表编码 if(details   != null && details.Length > 0) {     foreach(H3.DataModel.BizObject detail in   details)    {      string zz = detail["F0000001"]   + string.Empty; //获取子表中F0000001的字段值     } } 写在onsubmit前
