文本框之间内容的互相传递

namespace exchangeTest
{
    public partial class exchange : Form
    {
        public exchange()
        {
            InitializeComponent();
        }
        //往文本框二添加文本框一的内容
        private void btnExchange_Click(object sender, EventArgs e)
        {
            text2.Text = text2.Text + text1.Text;
            btnExchange.Enabled = false;
            btnExchange0.Enabled = true;
            btnExchange.Focus();
        }
        //往文本框一添加文本框二的内容
        private void btnExchange0_Click(object sender, EventArgs e)
        {
            text1.Text = text1.Text + text2.Text;
            btnExchange0.Enabled = false;
            btnExchange.Enabled = true;
            btnExchange.Focus();
        }
        //窗体装载，初始化控件，文本框获得输入焦点
        private void Form1_Load(object sender, EventArgs e)
        {
            text1.Text = null;
            text2.Text = null;
            text1.Focus();
        }
    }
