我在MSDN论坛上找到了解决方案。以下示例代码将从中删除所有
Click事件
button1。
public partial class Form1 : Form{ public Form1() { InitializeComponent(); button1.Click += button1_Click; button1.Click += button1_Click2; button2.Click += button2_Click; } private void button1_Click(object sender, EventArgs e) { MessageBox.Show("Hello"); } private void button1_Click2(object sender, EventArgs e) { MessageBox.Show("World"); } private void button2_Click(object sender, EventArgs e) { RemoveClickEvent(button1); } private void RemoveClickEvent(Button b) { FieldInfo f1 = typeof(Control).GetField("EventClick", BindingFlags.Static | BindingFlags.NonPublic); object obj = f1.GetValue(b); PropertyInfo pi = b.GetType().GetProperty("Events", BindingFlags.NonPublic | BindingFlags.Instance); EventHandlerList list = (EventHandlerList)pi.GetValue(b, null); list.RemoveHandler(obj, list[obj]); } }}
