5 个解决方案

#1

Button button = new Button();button.Click += (s,e) => { your code; };//button.Click += new EventHandler(button_Click);container.Controls.Add(button);//protected void button_Click (object sender, EventArgs e) { }

#2

The easier one for newbies:

对新手来说比较容易:

Button button = new Button();button.Click += new EventHandler(button_Click);protected void button_Click (object sender, EventArgs e){    Button button = sender as Button;    // identify which button was clicked and perform necessary actions}

#3

Simply add the eventhandler to the button when creating it.

创建时只需将eventhandler添加到按钮中。

 button.Click += new EventHandler(this.button_Click);void button_Click(object sender, System.EventArgs e){//your stuff...}

#4

It is much easier to do:

这样做要容易得多:

Button button = new Button();button.Click += delegate{   // Your code};

#5

Let's say you have 25 objects and want one process to handle any one objects click event. You could write 25 delegates or use a loop to handle the click event.

假设您有25个对象，并希望一个进程处理任何一个对象单击事件。您可以编写25个委托或使用一个循环来处理单击事件。

public form1(){    foreach (Panel pl  in Container.Components)    {        pl.Click += Panel_Click;    }}private void Panel_Click(object sender, EventArgs e){    // Process the panel clicks here    int index = Panels.FindIndex(a => a == sender);    ...}
