C# 两个窗体中相互切换的方法

注意将form2中的botton2的modyfier属性修改为public

form1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.Windows.Forms;   namespace test {     public partial class Form1 : Form     {         Form2 frm = new Form2();         public Form1()         {             InitializeComponent();         }           private void button1_Click(object sender, EventArgs e)         {             this.Hide();                       frm.Show();             frm.button2.Click +=button2_Click;         }         private void button2_Click(object sender, EventArgs e)         {             MessageBox.Show("form1");             this.Show();         }           private void Form1_Load(object sender, EventArgs e)         {           }     } }

form2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.Windows.Forms;   namespace test {     public partial class Form2 : Form     {         public Form2()         {             InitializeComponent();         }           private void button2_Click(object sender, EventArgs e)         {             MessageBox.Show("form2");             this.Hide();         }         } }
