　　编辑模块只实现了全选和时间个功能自动换行的功能还没写

　　如果需要全部源码的请留言或者发邮件至hen

　　版本

　　主要代码如下

　　using System;using System Collections Generic;using System ComponentModel;using System Data;using System Drawing;using System Text;using System Windows Forms;using System IO;

　　namespace MyNotePadpublic partial class MyNotePad : Formpublic MyNotePad()InitializeComponent();this toolStripStatusLabel Text = DateTime Now DayOfWeek ToString();

　　private void textBox _KeyPress(object sender KeyPressEventArgs e)//textBox Text += e KeyChar;

　　private void 退出ToolStripMenuItem_Click(object sender EventArgs e)Application Exit();

　　private void 日期ToolStripMenuItem_Click(object sender EventArgs e)if (this textBox SelectedText != )this textBox SelectedText = DateTime Now ToString();elsethis textBox Text += DateTime Now;

　　private void timer _Tick(object sender EventArgs e)this toolStripStatusLabel Text = 现在时间是: + DateTime Now ToString();

　　private void 状态栏ToolStripMenuItem_Click(object sender EventArgs e)if (this statusStrip Visible == false)this statusStrip Visible = true;elsethis statusStrip Visible = false;this textBox Height += ;

　　private void 关于MyNotePadAToolStripMenuItem_Click(object sender EventArgs e)About ab = new About();ab Show();

　　private void 全选ToolStripMenuItem_Click(object sender EventArgs e)this textBox SelectAll();

　　private void 字体ToolStripMenuItem_Click(object sender EventArgs e)if (fontDialog ShowDialog() == DialogResult OK)textBox Font = fontDialog Font;

　　private void 自动换行ToolStripMenuItem_Click(object sender EventArgs e)

　　private void 保存ToolStripMenuItem_Click(object sender EventArgs e)using (SaveFileDialog saveDig = new SaveFileDialog())saveDig Filter = @ 文本文档(* txt)|* txt ;saveDig FileName = * txt ;if (saveDig ShowDialog() == DialogResult OK)StreamWriter sw = new StreamWriter(saveDig FileName false System Text Encoding Default);sw Write(this textBox Text);sw Close();this Text = saveDig FileName;

　　private void 另存为ToolStripMenuItem_Click(object sender EventArgs e)using (SaveFileDialog saveDig = new SaveFileDialog())saveDig Filter = @ 文本文档(* txt)|* txt ;saveDig FileName = this Text;if (saveDig ShowDialog() == DialogResult OK)StreamWriter sw = new StreamWriter(saveDig FileName false System Text Encoding Default);sw Write(this textBox Text);sw Close();

　　private void 新建ToolStripMenuItem_Click(object sender EventArgs e)if (this textBox Text != )

　　DialogResult d = MessageBox Show（文件 + this Text + @ 的文字已经改变

　　想保存文件吗？ MyNotePad MessageBoxButtons YesNoCancel MessageBoxIcon Information MessageBoxDefaultButton Button MessageBoxOptions DefaultDesktopOnly）

　　switch (d)case DialogResult Yes:using (SaveFileDialog saveDig = new SaveFileDialog())saveDig Filter = @ 文本文档(* txt)|* txt ;saveDig FileName = * txt ;if (saveDig ShowDialog() == DialogResult OK)StreamWriter sw = new StreamWriter(saveDig FileName false System Text Encoding Default);sw Write(this textBox Text);sw Close();this Text = saveDig FileName;break;case DialogResult No:this textBox Text = ;break;case DialogResult Cancel:break;

　　default: System Diagnostics Debug Assert(false);break;

　　private void 打开ToolStripMenuItem_Click(object sender EventArgs e)if (this textBox Text != )
