用C#编写一个读取磁盘第一扇区的程序

1.运行结果

2.WinHex校验

3.程序

using System;
using System.IO;class Program
{static void Main(){try{// 以管理员权限运行此程序const string drivePath = @"\\.\G:";const int sectorSize = 512;  // 标准扇区大小// 打开逻辑驱动器（需要管理员权限）using (FileStream drive = new FileStream(drivePath,FileMode.Open,FileAccess.Read,FileShare.ReadWrite)){byte[] sector = new byte[sectorSize];int bytesRead = drive.Read(sector, 0, sectorSize);if (bytesRead != sectorSize){Console.WriteLine($"错误：只读取到 {bytesRead} 字节，预期 {sectorSize} 字节");return;}Console.WriteLine("成功读取引导扇区内容：");Console.WriteLine(BitConverter.ToString(sector).Replace("-", " "));// 可选：保存到文件File.WriteAllBytes("G_BootSector.bin", sector);Console.WriteLine("\n数据已保存到 G_BootSector.bin");}}catch (UnauthorizedAccessException){Console.WriteLine("错误：请以管理员权限运行程序");}catch (FileNotFoundException){Console.WriteLine("错误：找不到驱动器 G:");}catch (Exception ex){Console.WriteLine($"发生错误：{ex.Message}");}}
}
