C#实现窗口之间的传值

//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    }  }}
