怎么清除事件的响应函数？？

[piaoling]

在C#里面我给一个事件指定了几个响应函数,
怎么清除这些事件响应函数？？
在没有获得这些响应函数的引用的时候。

            this.Click += new EventHandler(Form1_Click);
            this.Click -= new EventHandler(Form1_Click);

this.tabTool.SelectedIndexChanged -= new System.EventHandler(this.tabTool_SelectedIndexChanged);

Attributes.Remove

[我自横刀香甜笑]

控件.事件 -= new EventHandler(委托方法);

利用反射修改它的委托"链表"

看下面的例子
先给Button5加几个
this.button5.Click += new EventHandler(button5_Click);
this.button5.Click += new EventHandler(button5_Click);
this.button5.Click += new EventHandler(button5_Click);
this.button5.Click += new EventHandler(button5_Click);
this.button5.Click += new EventHandler(button5_Click);

删除几个

PropertyInfo pi = (typeof(System.Windows.Forms.Button)).GetProperty("Events", 
BindingFlags.Instance | BindingFlags.NonPublic);
EventHandlerList ehl = (EventHandlerList)pi.GetValue(button5, null);
FieldInfo fi = (typeof(Control)).GetField("EventClick", BindingFlags.Static | BindingFlags.NonPublic);
Delegate d = ehl[fi.GetValue(null)];
if (d != null)
{
    System.Delegate[] dels = d.GetInvocationList();
    for (int i = 0; i < dels.Length; i++)
    {
        if (i < 3)
        {
             this.button5.Click -= (EventHandler)dels[i];
        }
    } 
}

this.Click -= new EventHandler(Form1_Click);
