说明：本人准备写一些C#有关的小技巧系列文章，这些文章含金量并不高，代码难度不大，不过因为问的次数比较多，从而导致本人决定用自己所知的方式写这一系列文章，可以看做“趣味导学”系列吧。
要展示的第一个例子就是获取系统磁盘情况和操作系统名称，获取的信息包括本机上所有磁盘盘符，磁盘类型（软驱、硬盘分区、光盘），磁盘文件类型（FAT32/NSFS），磁盘空间总大小及剩余空间大小等。为了方便查看代码，用控制台式编写。代码如下：
using
System;
using
System.Collections.Generic;
using
System.Text;
using
System.IO;
namespace
LocalDriveInfo
{
class Program
{ static void Main(string[] args) { string[] drives = System.Environment.GetLogicalDrives(); DriveInfo driveInfo = null; System.Console.WriteLine(GetOperationSystemInName()); System.Console.WriteLine("卷标 盘符 类型 文件系统 总大小(byte) 可用空间大小(byte)"); for (int i = 0; i < drives.Length; i++) { driveInfo = new DriveInfo(drives[i]); if (driveInfo.IsReady) { System.Console.WriteLine("{0} {1} {2} {3} {4} {5}", driveInfo.VolumeLabel, driveInfo.Name, driveInfo.DriveType, driveInfo.DriveFormat, driveInfo.TotalSize.ToString("###,###") /*/ (1024 * 1024)*/, driveInfo.AvailableFreeSpace.ToString("###,###") /*/ (1024*1024))*/);
} else { System.Console.WriteLine("{0} {1} {2} {3} {4} {5}", "", driveInfo.Name, driveInfo.DriveType, "", "", "", ""); } } System.Console.ReadLine(); } //// <summary> /// 获取系统名称 /// </summary> /// <returns></returns> public static string GetOperationSystemInName() { OperatingSystem os = System.Environment.OSVersion; string osName = "UNKNOWN"; switch (os.Platform) { case PlatformID.Win32Windows: switch (os.Version.Minor) { case 0: osName = "Windows 95"; break; case 10: osName = "Windows 98"; break; case 90: osName = "Windows ME"; break; } break; case PlatformID.Win32NT: switch (os.Version.Major) { case 3: osName = "Windws NT 3.51"; break; case 4: osName = "Windows NT 4"; break; case 5: if (os.Version.Minor == 0) { osName = "Windows 2000"; } else if (os.Version.Minor == 1) { osName = "Windows XP"; } else if (os.Version.Minor == 2) { osName = "Windows Server 2003"; } break; case 6: osName = "Longhorn"; break; } break; } return String.Format("{0},{1}", osName, os.Version.ToString()); } }
}
