UI.AddZhang AZ = new AddZhang();          //实例化子窗体                         
AZ.WindowStartupLocation = WindowStartupLocation.CenterScreen;
 AZ.Topmost = true;
AZ.ResizeMode = ResizeMode.NoResize;
 if (AZ.ShowDialog() == true)                      // 获取子窗体传回是点击了确定按钮还是取消按钮
{
DisplayKeJian();                                             //刷新子窗体修改后的数据

 }

 

 

 

     this.DialogResult = false;                          //子窗体传回取消按钮
