Exemplos

O exemplo seguinte lança uma exceção se tentar eliminar um diretório que não está vazio.

using System;
using System.IO;

class Test

    {
        // Specify the directories you want to manipulate.
        DirectoryInfo di1 = new DirectoryInfo(@"c:\MyDir");

        {
            // Create the directories.
            di1.Create();
            di1.CreateSubdirectory("temp");

            //This operation will not be allowed because there are subdirectories.
            Console.WriteLine("I am about to attempt to delete {0}", di1.Name);

Exemplos

O exemplo seguinte demonstra a eliminação de um diretório. Como o diretório foi removido, primeiro comenta a Delete linha para verificar se o diretório existe. Depois descomente a mesma linha de código para testar se a diretoria foi removida com sucesso.

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

Observações

Se o DirectoryInfo não tiver ficheiros ou subdiretórios, este método elimina o DirectoryInfo mesmo se recursive for false. Tentar eliminar um DirectoryInfo que não está vazio quando recursive é false lança um IOException.
