Beispiele

Im folgenden Beispiel wird eine Ausnahme ausgelöst, wenn Sie versuchen, ein nicht leeres Verzeichnis zu löschen.

using System.IO;

Ausnahmen

Beispiele

Im folgenden Beispiel wird das Löschen eines Verzeichnisses veranschaulicht. Da das Verzeichnis entfernt wird, kommentieren Sie zunächst die Delete Zeile aus, um zu testen, dass das Verzeichnis vorhanden ist. Entfernen Sie dann die Auskommentierung derselben Codezeile, um zu testen, dass das Verzeichnis erfolgreich entfernt wurde.

using System;
using System.IO;

public class DeleteTest
{
    public static void Main()
    {

        // Make a reference to a directory.
        DirectoryInfo di = new DirectoryInfo("TempDir");

        // Create the directory only if it does not already exist.
        if (!di.Exists)
            di.Create();

        // Create a subdirectory in the directory just created.
        DirectoryInfo dis = di.CreateSubdirectory("SubDir");

        // Process that directory as required.
        // ...

        // Delete the subdirectory. The true indicates that if subdirectories
        // or files are in this directory, they are to be deleted as well.
        dis.Delete(true);

        // Delete the directory.
        di.Delete(true);
    }
}

open System.IO

// Make a reference to a directory.
let di = DirectoryInfo "TempDir"

// Create the directory only if it does not already exist.
if not di.Exists then
    di.Create()

// Create a subdirectory in the directory just created.
let dis = di.CreateSubdirectory "SubDir"

// Process that directory as required.
// ...

// Delete the subdirectory. The true indicates that if subdirectories
// or files are in this directory, they are to be deleted as well.
dis.Delete true

// Delete the directory.
di.Delete true

Imports System.IO

Public Class DeleteTest

    Public Shared Sub Main()
        ' Make a reference to a directory.
        Dim di As New DirectoryInfo("TempDir")

        ' Create the directory only if it does not already exist.
        If di.Exists = False Then
            di.Create()
        End If

        Dim dis As DirectoryInfo = di.CreateSubdirectory("SubDir")
        ' Create a subdirectory in the directory just created.

        ' Process that directory as required.
        ' ...

        ' Delete the subdirectory. The true indicates that if subdirectories
        ' or files are in this directory, they are to be deleted as well.
        dis.Delete(True)

        ' Delete the directory.
        di.Delete(True)
    End Sub
End Class

Hinweise

Wenn die DirectoryInfo Datei oder Unterverzeichnisse nicht vorhanden sind, wird mit dieser Methode auch dann gelöscht DirectoryInfo , wenn recursive dies der Fall ist false. Beim Versuch, ein Element DirectoryInfo zu löschen, das nicht leer ist, wenn recursive ein IOExceptionFehler ausgelöst wirdfalse.
