使用匿名方法：

Button button1 = new Button();
button1.Click += delegate
                    {
                        // Do something 
                    };

使用带有显式参数的匿名方法：

With an anonymous method with explicit parameters:

Button button1 = new Button();
button1.Click += delegate (object sender, EventArgs e)
                    {
                        // Do something 
                    };

使用lambda语法表示匿名方法：

With lambda syntax for an anonymous method:

Button button1 = new Button();
button1.Click += (object sender, EventArgs e) =>
                    {
                        // Do something 
                    };

使用方法：

Button button1 = new Button();
button1.Click += button1_Click;

private void button1_Click(object sender, EventArgs e)
{
    // Do something
}
