用C#实现简单的控件数组

  Button[] btns = new Button[9];

  private void ShowButtonArray()
  {
   for(int i = 0; i < 9; i++)
   {
    btns[i] = new Button(); //这一句往往为初学者忽视，须知要创建对象的实例！
    btns[i].Location = new System.Drawing.Point(100 + 50 * (i % 3),100 + 50 * (i / 3));
    btns[i].Name = "btnTest";
    btns[i].Size = new System.Drawing.Size(48, 48);
    btns[i].Text = i.ToString();
    btns[i].Click += new System.EventHandler(this.btns_Click); //统一的事件处理
    this.Controls.Add(btns[i]); //在窗体上呈现控件
   }
  }

  private void btns_Click(object sender, System.EventArgs e)
  {
   MessageBox.Show(((Button)sender).Text + " was clicked !"); //通过sender判断激发事件的控件
  }

  private void Form1_Load(object sender, System.EventArgs e)
  {
   ShowButtonArray();
  }
