C#程序自动更新软件版本号

 1   if (Debugger.IsAttached)//判断是否调试编译，是的话则将当前年月日写入文件
 2             {
 3                 using (FileStream file = new FileStream(Application.StartupPath + "\\version", FileMode.OpenOrCreate))
 4                 {
 5                     byte[] data = Encoding.Default.GetBytes(DateTime.Now.Year + "" + DateTime.Now.Month.ToString("00") + "" + DateTime.Now.Day.ToString("00"));
 6                     file.Write(data, 0, data.Length);
 7                 }
 8             }
 9             //每次打开窗体时，获取version文件版本号，显示到程序窗口
10             using (FileStream file = new FileStream(Application.StartupPath + "\\version", FileMode.OpenOrCreate))
11             {
12                 byte[] byData = new byte[100];
13                 file.Seek(0, SeekOrigin.Begin);
14                 file.Read(byData, 0, 100);
15                 string a = " V" + Encoding.Default.GetString(byData).Trim(‘\0‘);
16                 this.Text += a;
17             }
