c#继承父类技巧,并增加新的实现

1 父类  partial class FormBillTemplet:Form

        /// <summary>
        /// 新单

        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        public  virtual   void  tsButtonNewBill_Click(object sender, EventArgs e)
        {
           Messagebox.Show("父亲类")
        }

 

 

2、 子类

  public partial class Form3 : MMS.Public.Controls .FormBillTemplet

 

 public override void tsButtonNewBill_Click(object sender, EventArgs e)
        {

           base.tsButtonNewBill_Click(sender, e);
           MessageBox.Show("新单");
         }

 

运行，点 tsButtonNewBill按钮则提示：

  Messagebox.Show("父亲类")

 MessageBox.Show("新单");
