FtpWebRequest.GetResponse Method

public:
 override System::Net::WebResponse ^ GetResponse();

public override System.Net.WebResponse GetResponse ();

override this.GetResponse : unit -> System.Net.WebResponse

Public Overrides Function GetResponse () As WebResponse

Returns

A WebResponse reference that contains an FtpWebResponse instance. This object contains the FTP server's response to the request.

Exceptions

Examples

The following code example demonstrates copying a file to a request's data stream and sending a request to append data to a file to the server. The example calls GetResponse to send the request and block until the response is returned by the server.

static bool AppendFileOnServer( 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 appended to the file on the server.
   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::AppendFile;
   StreamReader^ sourceStream = gcnew StreamReader( fileName );
   array<Byte>^fileContents = Encoding::UTF8->GetBytes( sourceStream->ReadToEnd() );
   sourceStream->Close();
   request->ContentLength = fileContents->Length;

   // This example assumes the FTP site uses anonymous logon.
   request->Credentials = gcnew NetworkCredential( "anonymous","janeDoe@contoso.com" );
   Stream^ requestStream = request->GetRequestStream();
   requestStream->Write( fileContents, 0, fileContents->Length );
   requestStream->Close();
   FtpWebResponse^ response = dynamic_cast<FtpWebResponse^>(request->GetResponse());
   Console::WriteLine( "Append status: {0}", response->StatusDescription );
   response->Close();
   return true;
}

public static bool AppendFileOnServer(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 appended to the file on the server.

    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.AppendFile;

    StreamReader sourceStream = new StreamReader(fileName);
    byte [] fileContents = Encoding.UTF8.GetBytes(sourceStream.ReadToEnd());
    sourceStream.Close();
    request.ContentLength = fileContents.Length;

    // This example assumes the FTP site uses anonymous logon.
    request.Credentials = new NetworkCredential ("anonymous","janeDoe@contoso.com");
    Stream requestStream = request.GetRequestStream();
    requestStream.Write(fileContents, 0, fileContents.Length);
    requestStream.Close();
    FtpWebResponse response = (FtpWebResponse) request.GetResponse();

    Console.WriteLine("Append status: {0}",response.StatusDescription);

    response.Close();
    return true;
}

Remarks

To access the FTP-specific properties, you must cast the WebResponse object returned by this method to FtpWebResponse.

GetResponse causes a control connection to be established, and might also create a data connection. GetResponse blocks until the response is received. To prevent this, you can perform this operation asynchronously by calling the BeginGetResponse and EndGetResponse methods in place of GetResponse.

If the Proxy property is set, either directly or in a configuration file, communications with the FTP server are made through the proxy.

If a WebException is thrown, use the Response and Status properties of the exception to determine the response from the server.

This member outputs trace information when you enable network tracing in your application. For more information, see Network Tracing in the .NET Framework.

Notes to Callers

This method generates network traffic.
