using System;
using System.IO;

class Program
{
    static void Main()
    {
        DriveInfo[] allDrives = DriveInfo.GetDrives();

        foreach (DriveInfo drive in allDrives)
        {
            Console.WriteLine("驱动器 {0}", drive.Name);
            Console.WriteLine("总磁盘空间: {0}", drive.TotalSize);
            Console.WriteLine("可用磁盘空间: {0}", drive.AvailableFreeSpace);
        }
    }
}
