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;
窗体及空间声明代码：

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();

}C#是一个简单、通用、面向对象的编程语言，它由微软Microsoft开发，继承了C和C++强大功能，并且去掉了一些它们的复杂特性，C#综合了VB简单的可视化操作和C++的高运行效率，以其强大的操作能力、优雅的语法风格、创新的语言特性和便捷的面向组件编程从而成为.NET开发的首选语言，但它不适用于编写时间急迫或性能非常高的代码，因为C#缺乏性能极高的应用程序所需要的关键功能。
