简单记事本程序菜单设计

Form1.cs的里面的代码！



using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace NotePadApp
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}

private void 新建NToolStripMenuItem_Click(object sender, EventArgs e)
{
NoteForm note = new NoteForm();
note.MdiParent = this;
note.Show();
}

private void 退出XToolStripMenuItem_Click(object sender, EventArgs e)
{
this.Close();
}

private void 关于AToolStripMenuItem_Click(object sender, EventArgs e)
{
MessageBox.Show("简单的记事本程序");
}

private void 打开OToolStripMenuItem_Click(object sender, EventArgs e)
{
string fileUrl = "";
OpenFileDialog openFileDialog1 = new OpenFileDialog();
openFileDialog1.InitialDirectory = "c://";
openFileDialog1.Filter = "txt files(*.txt)|*.txt|All files(*.*)|*.*";
openFileDialog1.RestoreDirectory = true;
if(openFileDialog1.ShowDialog()==DialogResult.OK)
{
fileUrl = openFileDialog1.FileName;
}
NoteForm note = new NoteForm();
note.MdiParent = this;
note.Show();
note.OpenFile(fileUrl);
}

private void 保存SToolStripMenuItem_Click(object sender, EventArgs e)
{
if(this.ActiveMdiChild != null)
{
NoteForm activeForm = (NoteForm)this.ActiveMdiChild;
activeForm.SaveFile();
}
}

private void 撤消UToolStripMenuItem_Click(object sender, EventArgs e)
{
if(this.ActiveMdiChild!=null)
{
NoteForm activeForm = (NoteForm)this.ActiveMdiChild;
activeForm.FrmUndo();
}
}

private void 重复RToolStripMenuItem_Click(object sender, EventArgs e)
{
if (this.ActiveMdiChild != null)
{
NoteForm activeForm = (NoteForm)this.ActiveMdiChild;
activeForm.FrmRedo();
}
}

private void 剪切TToolStripMenuItem_Click(object sender, EventArgs e)
{
if (this.ActiveMdiChild != null)
{
NoteForm activeForm = (NoteForm)this.ActiveMdiChild;
activeForm.FrmCut();
}
}

private void 复制CToolStripMenuItem_Click(object sender, EventArgs e)
{
if (this.ActiveMdiChild != null)
{
NoteForm activeForm = (NoteForm)this.ActiveMdiChild;
activeForm.FrmCopy();
}
}

private void 粘贴PToolStripMenuItem_Click(object sender, EventArgs e)
{
if (this.ActiveMdiChild != null)
{
NoteForm activeForm = (NoteForm)this.ActiveMdiChild;
activeForm.FrmPaste();
}
}

private void 全选AToolStripMenuItem_Click(object sender, EventArgs e)
{
if (this.ActiveMdiChild != null)
{
NoteForm activeForm = (NoteForm)this.ActiveMdiChild;
activeForm.FrmSelectAll();
}
}
}
}



再添加一个窗口！

相当于客户端！

命名为NotePadApp.cs

代码为

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;
using System.IO;

namespace NotePadApp
{
public partial class NoteForm : Form
{
string fileName = "";
public NoteForm()
{
InitializeComponent();
this.WindowState = FormWindowState.Maximized;
}
public void OpenFile(string fileUrl)
{
fileName = fileUrl;
StringBuilder sb = new StringBuilder();
using (StreamReader sr = File.OpenText(fileUrl))
{
string input = "";
while ((input = sr.ReadLine()) != null)
{
sb.Append(input);
}
sr.Close();
}
this.richTextBox1.Text = sb.ToString();
}
public void SaveFile()
{
if(fileName =="")
{
if(this.saveFileDialog1.ShowDialog()==DialogResult.OK)
{
fileName = saveFileDialog1.FileName;
}
}
using (StreamWriter sw= new StreamWriter(fileName))
{
sw.Write(this.richTextBox1.Text);
}
}
public void FrmCopy()
{
this.richTextBox1.Copy();
}
public void FrmPaste()
{
this.richTextBox1.Paste();
}
public void FrmCut()
{
this.richTextBox1.Cut();
}
public void FrmSelectAll()
{
this.richTextBox1.SelectAll();
}
public void FrmUndo()
{
this.richTextBox1.Undo();
}
public void FrmRedo()
{
this.richTextBox1.Redo();
}
}
}



最后值得一提的是快速建立菜单项 在工具栏里拖MenuStrip到窗口上，然后在MenuStrip的右上角那个键选择

一个标准菜单集合！在通过编辑项把多余的给删除就行了！
