Exceptions

Examples

The following code example demonstrates getting the response stream for a ListDirectory request.

static bool ListFilesOnServer( Uri^ serverUri )
{
   // The serverUri should start with the ftp:// scheme.
   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::ListDirectory;

   // Get the ServicePoint object used for this request, and limit it to one connection.
   // In a real-world application you might use the default number of connections (2),
   // or select a value that works best for your application.
   ServicePoint^ sp = request->ServicePoint;
   Console::WriteLine( "ServicePoint connections = {0}.", sp->ConnectionLimit );
   sp->ConnectionLimit = 1;
   FtpWebResponse^ response = dynamic_cast<FtpWebResponse^>(request->GetResponse());

   // The following streams are used to read the data returned from the server.
   Stream^ responseStream = nullptr;
   StreamReader^ readStream = nullptr;
   try
   {
      responseStream = response->GetResponseStream();
      readStream = gcnew StreamReader( responseStream,System::Text::Encoding::UTF8 );
      if ( readStream != nullptr )
      {
         // Display the data received from the server.
         Console::WriteLine( readStream->ReadToEnd() );
      }

      Console::WriteLine( "List status: {0}", response->StatusDescription );
   }
   finally
   {
      if ( readStream != nullptr )
      {
         readStream->Close();
      }

      if ( response != nullptr )
      {
         response->Close();
      }
   }

   return true;
}

public static bool ListFilesOnServer(Uri serverUri)
{
    // The serverUri should start with the ftp:// scheme.
    if (serverUri.Scheme != Uri.UriSchemeFtp)
    {
        return false;
    }
    // Get the object used to communicate with the server.
    FtpWebRequest request = (FtpWebRequest)WebRequest.Create(serverUri);
    request.Method = WebRequestMethods.Ftp.ListDirectory;

    // Get the ServicePoint object used for this request, and limit it to one connection.
    // In a real-world application you might use the default number of connections (2),
    // or select a value that works best for your application.

    ServicePoint sp = request.ServicePoint;
    Console.WriteLine("ServicePoint connections = {0}.", sp.ConnectionLimit);
    sp.ConnectionLimit = 1;

    FtpWebResponse response = (FtpWebResponse) request.GetResponse();

    // The following streams are used to read the data returned from the server.
    Stream responseStream = null;
    StreamReader readStream = null;
    try
    {
        responseStream = response.GetResponseStream();
        readStream = new StreamReader(responseStream, System.Text.Encoding.UTF8);

        if (readStream != null)
        {
            // Display the data received from the server.
            Console.WriteLine(readStream.ReadToEnd());
        }
        Console.WriteLine("List status: {0}",response.StatusDescription);
    }
    finally
    {
        if (readStream != null)
        {
            readStream.Close();
        }
        if (response != null)
        {
            response.Close();
        }
    }

    return true;
}

Remarks

After reading the data, you must close the stream. The stream is automatically closed when you close the FtpWebResponse object that contains it.

An exception is thrown unless the request method is DownloadFile or ListDirectory.
