c#利用委托传递函数参数（1）

本次旨在解决 同参不同名 的函数作为参数传递的情况

情景：

一下两个函数分别多次重复调用了两个同参不同名的函数（实际上总共有3个这样的函数），函数结构基本相同，只有调用的函数名不一样，显然可以整合在一个函数中，减少代码量；

 private void button1_Click(object sender, EventArgs e)
         {
             clsLineSeg.UpdateDiseasePostion(map, tblRouteData, "Z001522600");
             clsLineSeg.UpdateDiseasePostion(map, tblRouteData, "C800522635");
             clsLineSeg.UpdateDiseasePostion(map, tblRouteData, "X890522635");
             clsLineSeg.UpdateDiseasePostion(map, tblRouteData, "Y003522635");
             clsLineSeg.UpdateDiseasePostion(map, tblRouteData, "X899522635");
             clsLineSeg.UpdateDiseasePostion(map, tblRouteData, "C018522635");
             clsLineSeg.UpdateDiseasePostion(map, tblRouteData, "S311520000");
             MessageBox.Show("ok");
         }        

         private void btnUpdateAssetGps_Click(object sender, EventArgs e)
         {
             clsLineSeg.UpdateAssetDataGpsPostion(map, tblRouteData, "Z001522600");
             clsLineSeg.UpdateAssetDataGpsPostion(map, tblRouteData, "C800522635");
             clsLineSeg.UpdateAssetDataGpsPostion(map, tblRouteData, "X890522635");
             clsLineSeg.UpdateAssetDataGpsPostion(map, tblRouteData, "Y003522635");
             clsLineSeg.UpdateAssetDataGpsPostion(map, tblRouteData, "X899522635");
             clsLineSeg.UpdateAssetDataGpsPostion(map, tblRouteData, "C018522635");
             clsLineSeg.UpdateAssetDataGpsPostion(map, tblRouteData, "S311520000");
             MessageBox.Show("ok");
         }

方案：

但是要想完全统一，肯定需要将要调用的函数作为新函数的参数传递进去，这里就可以用到c#的委托，如下：

    public delegate void UpdateMethodHandler(IMap map, ITable tblRouteData,string routeCode);//声明委托

 //修改简化待调用函数
 public void UpdateAssetDataGps84Postion(IMap map, ITable tblRouteData, string routeCode)
         {
             clsLineSeg.UpdateAssetDataGps84Postion(map, tblRouteData, routeCode);
         }

         public void UpdateDiseasePostion(IMap map, ITable tblRouteData, string routeCode)
         {
             clsLineSeg.UpdateDiseasePostion(map, tblRouteData, routeCode);
         }

 //利用委托传递函数名参数
         public void btnUpdateClick(UpdateMethodHandler UpdateMethodHandler)
         {
             var routeLst = GetRouteLst();
             if(routeLst==null||routeLst.Length<=)
             {
                 MessageBox.Show("请输入路线编码！");
                 return;
             }
             foreach(var r in routeLst)
             {
                 UpdateMethodHandler(map, tblRouteData, r);
             }
             MessageBox.Show("ok");
         }

 //函数调用简化
         private void btnUpdateStakeTable_Click(object sender, EventArgs e)
         {
             btnUpdateClick(UpdateAssetDataGps84Postion);
             //clsLineSeg.UpdateAssetDataGps84Postion(map, tblRouteData, "Z001522600");
             //clsLineSeg.UpdateAssetDataGps84Postion(map, tblRouteData, "C800522635");
             //clsLineSeg.UpdateAssetDataGps84Postion(map, tblRouteData, "X890522635");
             //clsLineSeg.UpdateAssetDataGps84Postion(map, tblRouteData, "Y003522635");
             //clsLineSeg.UpdateAssetDataGps84Postion(map, tblRouteData, "X899522635");
             //clsLineSeg.UpdateAssetDataGps84Postion(map, tblRouteData, "C018522635");
             //clsLineSeg.UpdateAssetDataGps84Postion(map, tblRouteData, "S311520000");
             //MessageBox.Show("ok");
         }
