Esempio

Questo esempio di codice fa parte di un esempio più ampio fornito per il FileStream(String, FileMode, FileAccess, FileShare, Int32, Boolean) costruttore.

   {
      State^ tempState = dynamic_cast<State^>(asyncResult->AsyncState);
      int readCount = tempState->FStream->EndRead( asyncResult );
      int i = 0;
      while ( i < readCount )
      {
         if ( tempState->ReadArray[ i ] != tempState->WriteArray[ i++ ] )

            tempState->FStream->Close();

Commenti

Se il percorso assoluto non è noto, questa proprietà restituisce una stringa simile a "[Unknown]".
