创建动态控件：

btn[0]=new Button();

这样就行了 

public Form1()

        {

            InitializeComponent();

            Button[] btn = new Button[3];

            int Top= 0;

            for (int i = 0; i < 3; i++)

            {

                btn[i] = new Button();

                btn[i].Top = Top;

                this.Controls.Add(btn[i]);

                Top += 30;

            }

        } 

 

private void textBox_KeyPress(object sender,System.Windows.Forms.KeyPressEventArgs e){  TextBox box = (TextBox)sender;   MessageBox.Show(this,"you choose " + box.Name + " and you keypress " + e.KeyChar.ToString() ,"try" ,MessageBoxButtons.OK );  } 本篇文章来源于：开发学院 http://edu.codepub.com   原文链接：http://edu.codepub.com/2009/1008/16215.php
