Ruft die Gesamtgröße des Speicherplatzes auf einem Laufwerk in Byte ab.

public:
 property long TotalSize { long get(); };
public long TotalSize { get; }
member this.TotalSize : int64
Public ReadOnly Property TotalSize As Long

Eigenschaftswert

Int64

Die Gesamtgröße des Laufwerks in Byte.

Ausnahmen

UnauthorizedAccessException

Der Zugriff auf die Laufwerkinformationen wird verweigert.

DriveNotFoundException

Das Laufwerk ist nicht zugeordnet oder nicht vorhanden.

IOException

Ein E/A-Fehler ist aufgetreten (z. B. ein Datenträgerfehler oder ein Laufwerk war nicht bereit).

Beispiele

Das folgende Codebeispiel veranschaulicht die Verwendung der DriveInfo Klasse zum Anzeigen von Informationen zu allen Laufwerken im aktuellen System.

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)
            {
                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);
            }
        }
    }
