{
public partial class Form1 : Form
{
 public Form1()
 {
  InitializeComponent();
 }
 //Open file 菜单选项
 private void openFileToolStripMenuItem_Click(object sender, EventArgs e)
 {
  openFileDialog1.Filter = "txt files(*.txt)|*.txt";
  if(openFileDialog1.ShowDialog()==DialogResult.OK)
  {
   richTextBox1.LoadFile(openFileDialog1.FileName, RichTextBoxStreamType.PlainText);
  }
 }
 //Save file 菜单选项

 {
  saveFileDialog1.Filter = "txt files(*.txt)|*.txt";
  if(saveFileDialog1.ShowDialog()==DialogResult.OK)
  {
   richTextBox1.SaveFile(saveFileDialog1.FileName, RichTextBoxStreamType.PlainText);

 }
 //exit file 菜单选项
 private void exitToolStripMenuItem_Click(object sender, EventArgs e)

 }
 //About 菜单选项
 private void aboutToolStripMenuItem_Click(object sender, EventArgs e)
 {
  Form2 frm = new Form2();
  frm.ShowDialog();
 }
}
}

//form2.cs
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;
