O exemplo a seguir demonstra como mover um diretório.

   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" );
   
   // Move the main directory. Note that the contents move with the directory.
   if (  !Directory::Exists( "NewTempDir" ) )
      di->MoveTo( "NewTempDir" );

   try
   {

Comentários

Esse método lança um IOException se, por exemplo, você tentar mover c:\mydir para c:\public e c:\public já existe. Você deve especificar "c:\\public\\mydir" como o destDirName parâmetro ou especificar um novo nome de diretório, como "c:\\newdir".

Esse método permite mover um diretório para um diretório somente leitura. O atributo de leitura/gravação de nenhum diretório é afetado.
