Esempio

Nell'esempio di codice seguente viene caricato un file in un server e viene visualizzato lo stato.

static bool UploadFileToServer( String^ fileName, Uri^ serverUri )
{
   // The URI described by serverUri should use the ftp:// scheme.
   // It contains the name of the file on the server.
   // Example: ftp://contoso.com/someFile.txt.
   // 
   // The fileName parameter identifies the file containing the data to be uploaded.
   if ( serverUri->Scheme != Uri::UriSchemeFtp )
   {
      return false;
   }

   // Get the object used to communicate with the server.
   FtpWebRequest^ request = dynamic_cast<FtpWebRequest^>(WebRequest::Create( serverUri ));
   request->Method = WebRequestMethods::Ftp::UploadFile;

   // Don't set a time limit for the operation to complete.
   request->Timeout = System::Threading::Timeout::Infinite;

   // Copy the file contents to the request stream.
   const int bufferLength = 2048;
   array<Byte>^buffer = gcnew array<Byte>(bufferLength);
   int count = 0;
   int readBytes = 0;
   FileStream^ stream = File::OpenRead( fileName );
   Stream^ requestStream = request->GetRequestStream();
   do
   {
      readBytes = stream->Read( buffer, 0, bufferLength );
      requestStream->Write( buffer, 0, bufferLength );
      count += readBytes;
   }
   while ( readBytes != 0 );

   Console::WriteLine( "Writing {0} bytes to the stream.", count );
   
   // IMPORTANT: Close the request stream before sending the request.
   requestStream->Close();
   FtpWebResponse^ response = dynamic_cast<FtpWebResponse^>(request->GetResponse());
   Console::WriteLine( "Upload status: {0}, {1}", response->StatusCode, response->StatusDescription );
   response->Close();
   return true;
}

Commenti

Il valore restituito dalla StatusCode proprietà è incluso nella StatusDescription proprietà . Quando si scaricano dati, il valore delle modifiche come codici di StatusCode stato viene restituito dal server FTP. Dopo aver chiamato il GetResponse metodo, StatusCode contiene un codice di stato intermedio. Quando si chiama il Close metodo, StatusCode contiene lo stato finale.
