Hello World!
你是要多简单的？源代码？

先定义一个委托 public delegate void DoTestAction(object o);
然后定义一个和该委托参数和返回值一致的方法
public void TestAction(object o) {
//doaction here.
}
申明
public DoTestAction testAction;
赋值并调用
public DoTestAction testAction;
public void DoIt() {
testAction += new DoTestAction(TestAction);
object o = new object();
testAction(o);
}

protected override void OnInit(EventArgs e)
{
InitializeComponent();
base.OnInit(e);
}
private void InitializeComponent()
{
this.btZH.Click += new System.EventHandler(this.btZH_Click);
this.btEN.Click += new System.EventHandler(this.btEN_Click);
this.btVN.Click += new System.EventHandler(this.btVN_Click);
this.btInquire.Click += new System.EventHandler(this.btInquire_Click);
//this.btDetails.Click += new System.EventHandler(this.btLookCertDetails_Click);
//this.GridView1.RowCreated += new GridViewRowEventHandler(this.GridView1_RowCreated);
this.Load += new System.EventHandler(this.Page_Load);
}
