功能实现

本程序有两个窗体，分别为Form1和AboutBox1

所有文件如下：

对于Form1：
需要引入的类库：

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

窗体载入：

private void Form1_Load(object sender, EventArgs e)  {   this.editBox1.ScrollBars = ScrollBars.Both;   this.editBox2.ScrollBars = ScrollBars.Both;   this.Text = textFileName + " - " + programeName;//显示文件名   this.timer1.Start();   editBox1.Focus();  }

首先进行一些固定变量声明：

private string textFileName = "无标题";private string programeName = "Icey";private string filePath = "";private string asFilePath = "";private string selecteText = "";private string helpUrl = "https://blog.mayuko.cn/icey";private string openSourceUrl = "https://github.com/mayuko2012/icey";private string wrongMessage = "你好像遇到了错误...";private string fileFormat = "文本文件(*.txt)|*.txt|Icey文件(*.ice)|*.ice|C++文件(*.cpp)|*.cpp|C文件(*.c)|*.c|所有文件(*.*)|(*.*)";private string tabFileName1 = "无标题1 - Icey";private string tabFileName2 = "无标题2 - Icey";  Boolean saveFileStatus1 = false;  Boolean textChanged1 = false;  Boolean saveFileStatus2 = false;  Boolean textChanged2 = false;

保存文件采用函数形式：

private void saveFile()//保存  {   if (!textFileName.Equals(""))   {    SaveFileDialog saveFile = new SaveFileDialog();    saveFile.Filter = fileFormat;    saveFile.FileName = "*.txt";    if (saveFile.ShowDialog() == DialogResult.OK)    {     filePath = saveFile.FileName;     StreamWriter sw = new StreamWriter(filePath, false, Encoding.Default);     sw.Write((editBox1.Focused) ? editBox1.Text : editBox2.Text);     sw.Close();     if (editBox1.Focused)     {      tabFileName1 = saveFile.FileName + " - " + programeName;      saveFileStatus1 = true;     }     else if (editBox2.Focused)     {      tabFileName2 = saveFile.FileName + " - " + programeName;      saveFileStatus2 = true;     }    }   }   toolStripStatusLabel4.Text = "已保存";  }

另存为采用函数形式：

private void saveAsFile()//另存为  {   SaveFileDialog saveAsFile = new SaveFileDialog();   saveAsFile.Filter = fileFormat;   saveAsFile.FileName = "*.txt";   if (saveAsFile.ShowDialog() == DialogResult.OK)   {    asFilePath = saveAsFile.FileName;    StreamWriter sw = new StreamWriter(asFilePath, false, Encoding.Default);    sw.WriteLine((editBox1.Focused) ? editBox1.Text : editBox2.Text);    sw.Close();    FileInfo fileInfo = new FileInfo(saveAsFile.FileName);    textFileName = fileInfo.Name;   }   toolStripStatusLabel4.Text = "已保存";}

新建函数：

 private void newFile()//新建  {   if (editBox1.Focused)   {    if (editBox1.Text != String.Empty && saveFileStatus1 == false && textChanged1 == true)//如果文本框不为空    {     DialogResult result = MessageBox.Show("是否将窗口1已编辑文件保存到 " + textFileName, wrongMessage, MessageBoxButtons.YesNoCancel, MessageBoxIcon.Information);     if (result == DialogResult.Yes)     {      saveFile();      Application.Exit();     }     else if (result == DialogResult.No)     {      editBox1.Text = "";     }    }    else     editBox1.Text = "";   }   else if (editBox2.Focused)   {    if (editBox2.Text != String.Empty && saveFileStatus2 == false && textChanged2 == true)//如果文本框不为空    {     DialogResult result = MessageBox.Show("是否将窗口2已编辑文件保存到 " + textFileName, wrongMessage, MessageBoxButtons.YesNoCancel, MessageBoxIcon.Information);     if (result == DialogResult.Yes)     {      saveFile();      Application.Exit();     }     else if (result == DialogResult.No)     {      editBox2.Text = "";     }    }    else     editBox2.Text = "";   } }

打开文件函数：

private void openFile()//打开   {    OpenFileDialog openFile = new OpenFileDialog();    openFile.Filter = fileFormat;    if (openFile.ShowDialog() == DialogResult.OK)    {     StreamReader sr = new StreamReader(openFile.FileName, Encoding.Default);     if (editBox1.Focused)     {      editBox1.Text = sr.ReadToEnd();     }     else if(editBox2.Focused)     {      editBox2.Text = sr.ReadToEnd();     }     sr.Close();     FileInfo fileInfo = new FileInfo(openFile.FileName);     if (editBox1.Focused)     {      tabFileName1 = fileInfo.Name + " - " + programeName;      saveFileStatus1 = true;     }     else if (editBox2.Focused)     {      tabFileName2 = fileInfo.Name + " - " + programeName;      saveFileStatus2 = true;     }     textFileName = fileInfo.Name;    }}

全屏模式函数：

private void fullScreen()//全屏  {   if (全屏模式ToolStripMenuItem.Checked == false)   {    this.WindowState = FormWindowState.Maximized;    全屏模式ToolStripMenuItem.Checked = true;    this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;   }   else   {    this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.Sizable;    this.WindowState = FormWindowState.Normal;    全屏模式ToolStripMenuItem.Checked = false;   }}

退出菜单命令：

private void 退出ToolStripMenuItem_Click(object sender, EventArgs e)  {   if (editBox1.Text != String.Empty || saveFileStatus1 == false && textChanged1 == true)   {    this.tabPage1.Show();    this.editBox1.Focus();    DialogResult result = MessageBox.Show("是否将窗口1已编辑文件保存到 " + textFileName, wrongMessage, MessageBoxButtons.YesNoCancel, MessageBoxIcon.Information);    if (result == DialogResult.Yes)    {     saveFile();     Application.Exit();    }    else if (result == DialogResult.No)    {     Application.Exit();    }   }   else if (editBox2.Text != String.Empty || saveFileStatus2 == false && textChanged2 == true)   {    this.tabPage2.Show();    this.editBox2.Focus();    DialogResult result = MessageBox.Show("是否将窗口2已编辑文件保存到 " + textFileName, wrongMessage, MessageBoxButtons.YesNoCancel, MessageBoxIcon.Information);    if (result == DialogResult.Yes)    {     saveFile();     Application.Exit();    }    else if (result == DialogResult.No)    {     Application.Exit();    }   }   else    Application.Exit();}

Bool变量，用于判断TextBox是否发生变化：

private void textBox1_TextChanged(object sender, EventArgs e)  {   textChanged2 = true;   toolStripStatusLabel4.Text = "已修改";  }  private void editBox2_TextChanged(object sender, EventArgs e)  {   textChanged2 = true;   toolStripStatusLabel4.Text = "已修改";  }
