Ejemplos

En el ejemplo siguiente se muestra el uso de la DriveInfo clase para mostrar información sobre todas las unidades del sistema actual.

using System;
using System.IO;

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

        foreach (DriveInfo d in allDrives)
        {
            Console.WriteLine("Drive {0}", d.Name);
            Console.WriteLine("  Drive type: {0}", d.DriveType);
            if (d.IsReady == true)
            {
                Console.WriteLine("  Volume label: {0}", d.VolumeLabel);
                Console.WriteLine("  File system: {0}", d.DriveFormat);
                Console.WriteLine(
                    "  Available space to current user:{0, 15} bytes",
                    d.AvailableFreeSpace);

                Console.WriteLine(
                    "  Total available space:          {0, 15} bytes",
                    d.TotalFreeSpace);

                Console.WriteLine(
                    "  Total size of drive:            {0, 15} bytes ",
                    d.TotalSize);
            }
        }
    }

Comentarios

El sistema operativo determina la longitud de la etiqueta. Por ejemplo, NTFS permite que una etiqueta de volumen tenga hasta 32 caracteres de longitud. Tenga en cuenta que null es un válido VolumeLabel.
