以编程方式将Button属性绑定到索引器对象

using System;
using System.Windows.Forms;

public class ButtonIndexer
{
    private Button[] buttons;

    public ButtonIndexer(int size)
    {
        buttons = new Button[size];
    }

    public Button this[int index]
    {
        get { return buttons[index]; }
        set { buttons[index] = value; }
    }
}

public class Program
{
    public static void Main()
    {
        ButtonIndexer buttonIndexer = new ButtonIndexer(3);

        // 创建Button对象并设置属性
        Button button1 = new Button();
        button1.Text = "Button 1";

        Button button2 = new Button();
        button2.Text = "Button 2";

        Button button3 = new Button();
        button3.Text = "Button 3";

        // 将Button对象添加到索引器对象中
        buttonIndexer[0] = button1;
        buttonIndexer[1] = button2;
        buttonIndexer[2] = button3;

        // 绑定属性
        buttonIndexer[0].Click += (sender, e) => Console.WriteLine("Button 1 clicked");
        buttonIndexer[1].Click += (sender, e) => Console.WriteLine("Button 2 clicked");
        buttonIndexer[2].Click += (sender, e) => Console.WriteLine("Button 3 clicked");

        // 使用索引器对象
        buttonIndexer[0].PerformClick();  // 模拟点击Button 1
        buttonIndexer[1].PerformClick();  // 模拟点击Button 2
        buttonIndexer[2].PerformClick();  // 模拟点击Button 3
    }
}
