Ejemplos

En el ejemplo siguiente se muestra cómo eliminar un directorio. Dado que se quita el directorio, primero convierta en comentario la Delete línea para probar que el directorio existe. A continuación, quite la marca de comentario de la misma línea de código para probar que el directorio se quitó correctamente.

using namespace System;
using namespace System::IO;
int main()
{
   
   // Make a reference to a directory.
   DirectoryInfo^ di = gcnew 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 );
}

        if (di.Exists == false)
            di.Create();

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

        // Process that directory as required.

Si no DirectoryInfo tiene archivos o subdirectorios, este método elimina incluso DirectoryInfo si recursive es false. Intentando eliminar un que DirectoryInfo no está vacío cuando recursive se false produce una IOExceptionexcepción .
