如何将文本从一个文本框添加到另一个文本框？

Question

基本上我正在制作一个简单的程序来帮助记录我的工作.我有一行textbox1和一行textbox2.

我希望能够输入任何内容textbox1,然后按"输入"并显示在第一行中textbox2.任何帮助,将不胜感激.

    public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();

    }

    private void textbox1_TextChanged(object sender, EventArgs e)
    {

    }

    private void textBox2_TextChanged(object sender, EventArgs e)
    {

    }
}

Answer 1

//in form constructor, or InitializeComponent method
textBox1.Validated += DoValidateTextBox;



//in another place of your class
private void DoValidateTextBox(object sender, EvenArgs e) {
  textBox2.Text =  ((TextBox)sender).Text + Environment.NewLine + textBox2.Text;
}
