为了解决在多个窗口之间的传值问题，我们可以通过设置静态类和静态变量的办法来实现窗口间值的传递

窗体一代码

//窗体1的代码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 WindowsFormsApplication1{ public partial class Form1 : Form { public Form1() { InitializeComponent(); } private void button1_Click(object sender, EventArgs e) { sharedclass.sharedvalue = textBox1.Text.ToString(); //静态变量的用法：类名.变量名 赋值给静态变量 Form2 frm2 = new Form2(); frm2.Show(); } } public static class sharedclass //在命名空间设置一个静态类sharedclass，不要放置在form1前面 { public static string sharedvalue; //设置一个静态变量sharedvalue }}

窗体2代码

//窗体2的代码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 WindowsFormsApplication1{ public partial class Form2 : Form { public Form2() { InitializeComponent(); textBox1.Text = sharedclass.sharedvalue; //静态变量传入给窗口2的textBox } }}
