C/S开发框架教程：使用基础资料(数据字典)的DAL层更新主从表（或多表）数据
C/S开发框架教程：使用基础资料(数据字典)的DAL层更新主从表（或多表）数据
CSFramework C/S开发框架作为标准三层开发框架，为用户提供大量的例子参考，快速入门，实战开发。
界面层【测试按钮】的Click事件：
C# Code:
private void button1_Click(object sender, EventArgs e)
{
//获取采购订单PO的数据表结构
var bll = new bllPO();
var ds = bll.GetDataByKey("-", false);
//主表：添加一条记录
var R1 = ds.Tables[tb_PO.__TableName].Rows.Add();
R1[tb_PO.PODate] = DateTime.Today;
R1[tb_PO.Amount] = 15000;
//明细表：添加记录1
var D1 = ds.Tables[tb_POs.__TableName].Rows.Add();
D1[tb_POs.ProductCode] = "CS5";
D1[tb_POs.Quantity] = 100;
D1[tb_POs.Price] = 50;
D1[tb_POs.Amount] = 5000;
//明细表：添加记录2
var D2 = ds.Tables[tb_POs.__TableName].Rows.Add();
D2[tb_POs.ProductCode] = "CS4";
D2[tb_POs.Quantity] = 200;
D2[tb_POs.Price] = 50;
D2[tb_POs.Amount] = 10000;
//模拟使用基础资料(数据字典)的DAL层更新主从表（或多表）数据
var result = bll.UpdateByDatadictDAL(ds);
Msg.ShowInformation($"保存{(result ? "成功" : "失败")}");
//模拟使用基础资料(数据字典)的DAL层更新主从表（或多表）数据
var result1 = bll.UpdateByDatadictDAL_ex(ds);
Msg.ShowInformation($"保存{(result1.Success ? "成功" : "失败")},单据号码：{result1.PrimaryKey}");
}

BLL层的方法：
C# Code:
public bool UpdateByDatadictDAL(DataSet ds)
{
//更新公共字段默认值
foreach (DataTable T in ds.Tables) this.UpdateCommonFieldsValue(T);
//保存数据
return new dalPO_DataDictUpdate(Loginer.CurrentUser).Update(ds);
}
public SaveResultEx UpdateByDatadictDAL_ex(DataSet ds)
{
//更新公共字段默认值
foreach (DataTable T in ds.Tables) this.UpdateCommonFieldsValue(T);
//保存数据
return new dalPO_DataDictUpdate(Loginer.CurrentUser).UpdateEx(ds);
}

public bool UpdateByDatadictDAL(DataSet ds)
{
//更新公共字段默认值
foreach (DataTable T in ds.Tables) this.UpdateCommonFieldsValue(T);
//保存数据
return new dalPO_DataDictUpdate(Loginer.CurrentUser).Update(ds);
}
public SaveResultEx UpdateByDatadictDAL_ex(DataSet ds)
{
//更新公共字段默认值
foreach (DataTable T in ds.Tables) this.UpdateCommonFieldsValue(T);
//保存数据
return new dalPO_DataDictUpdate(Loginer.CurrentUser).UpdateEx(ds);
