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：

窗体载入：

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：
