Property Value

Uri

A Uri instance that identifies the resource associated with this response.

Examples

The following code example displays the value of this property.

static bool DownloadFileFromServer( Uri^ serverUri, String^ localFileName )
{
   // The serverUri parameter should start with the ftp:// scheme.
   if ( serverUri->Scheme != Uri::UriSchemeFtp )
   {
      return false;
   }

   // Get the object used to communicate with the server.
   // Note that the cast to FtpWebRequest is done only
   // for the purposes of illustration. If your application
   // does not set any properties other than those defined in the
   // System.Net.WebRequest class, you can use the following line instead:
   // WebRequest request = WebRequest.Create(serverUri);
   //
   FtpWebRequest^ request = dynamic_cast<FtpWebRequest^>(WebRequest::Create( serverUri ));
   request->Method = WebRequestMethods::Ftp::DownloadFile;
   FtpWebResponse^ response = dynamic_cast<FtpWebResponse^>(request->GetResponse());
   Stream^ responseStream = nullptr;
   StreamReader^ readStream = nullptr;
   StreamWriter^ writeStream = nullptr;
   try
   {
      responseStream = response->GetResponseStream();
      readStream = gcnew StreamReader( responseStream,System::Text::Encoding::UTF8 );
      
      // Display information about the data received from the server.
      Console::WriteLine( "Bytes received: {0}", response->ContentLength );
      Console::WriteLine( "Message from server: {0}", response->StatusDescription );
      Console::WriteLine( "Resource: {0}", response->ResponseUri );

      // Write the bytes received from the server to the local file.
      if ( readStream != nullptr )
      {
         writeStream = gcnew StreamWriter( localFileName,false );
         writeStream->Write( readStream->ReadToEnd() );
      }
   }
   finally
   {
      if ( readStream != nullptr )
      {
         readStream->Close();
      }

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

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

   return true;
}

    //
    FtpWebRequest request = (FtpWebRequest)WebRequest.Create(serverUri);
    request.Method = WebRequestMethods.Ftp.DownloadFile;

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

    Stream responseStream = null;

        Console.WriteLine("Message from server: {0}", response.StatusDescription);
        Console.WriteLine("Resource: {0}", response.ResponseUri);

        // Write the bytes received from the server to the local file.
        if (readStream != null)
        {
            writeStream = new StreamWriter(localFileName, false);
            writeStream.Write(readStream.ReadToEnd());
        }
    }
    finally
    {

        {
            readStream.Close();
        }
        if (response != null)
        {
            response.Close();
        }
        if (writeStream != null)
        {
            writeStream.Close();
        }
    }
    return true;
}

Remarks

Because of server- and resource-specific behaviors, such as redirection, the value returned by the RequestUri property is not always the same as the value returned by the ResponseUri property.

For requests that use the UploadFileWithUniqueName method, ResponseUri returns the name of the file on the server.
