Question

Form1里textBox输入字符后，点击Form2的button，Form1的textBox要在Form2以MessageBox.Show()现实传递值

using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;代码如下：using System.Linq;using System.Text;using System.Threading.Tasks;using System.Windows.Forms;namespace WindowsFormsApplication12{ public partial class Form1 : Form { public Form1() { InitializeComponent(); } private void button1_Click(object sender, EventArgs e) { Form2 myfrom2 = new Form2(); myfrom2.Show(); } }}using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Linq;using System.Text;using System.Threading.Tasks;using System.Windows.Forms;namespace WindowsFormsApplication12{ public partial class Form2 : Form { public Form2() { InitializeComponent(); } private void button1_Click(object sender, EventArgs e) { Form1 myform1 = new Form1(); MessageBox.Show(myform1.textBox1.Text); } }}但是最后MessageBox.Show()现实的是Form1的textbox 属性的值。而不是在textbox里输入的值，请问这是为什么？

Answer 1

在form1中的所有textbox的事件中添加以下代码：
Form2 frm=new Form2();
frm.setLabelText(textbox.Text);

在Form2中添加公共方法setLabelText(string text)
添加代码：this.labl.Text=text;

麻烦能帮忙写一个完整的代码么？
