推荐答案

很简单.假设您使用面板来保存控件(它只是使控件保持一致并使代码更简单)

It''s pretty easy. Assuming that you use a Panel to hold the controls (it just keeps them togther and makes the code simpler)

Button b = new Button();
    b.Click += new EventHandler(MyDynamicButton_Click);
    MyPanel.Controls.Add(b);
    }

void MyDynamicButton_Click(object sender, EventArgs e)
    {
    foreach (Control c in MyPanel.Controls)
        {
        TextBox tb = c as TextBox;
        if (tb != null)
            {
            Console.WriteLine(tb.Text);
            }
        }
    }

您可以执行类似的操作来添加文本框.您可能需要设置按钮位置"和文本"属性.

You do a similar thing to add your text box. You will probably need to set the Button Location and Text properties, among others.
