Examples

The following code example sets this property to DeleteFile.

static bool DeleteFileOnServer( Uri^ serverUri )
{
   // The serverUri parameter should use the ftp:// scheme.
   // It contains the name of the server file that is to be deleted.
   // Example: ftp://contoso.com/someFile.txt.
   // 
   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::DeleteFile;
   FtpWebResponse^ response = dynamic_cast<FtpWebResponse^>(request->GetResponse());
   Console::WriteLine( "Delete status: {0}", response->StatusDescription );
   response->Close();
   return true;
}

public static bool DeleteFileOnServer(Uri serverUri)
{
    // The serverUri parameter should use the ftp:// scheme.
    // It contains the name of the server file that is to be deleted.
    // Example: ftp://contoso.com/someFile.txt.
    //

    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.DeleteFile;

    FtpWebResponse response = (FtpWebResponse) request.GetResponse();
    Console.WriteLine("Delete status: {0}",response.StatusDescription);
    response.Close();
    return true;
}

Remarks

The Method property determines which command is sent to the server. You set the Method by using the strings defined in the public field members of the WebRequestMethods.Ftp class. Note that the strings defined in the WebRequestMethods.Ftp class are the only supported options for the Method property. Setting the Method property to any other value will result in an ArgumentException exception.

When setting Method to UploadFile, you must do so before calling the GetRequestStream method. Failure to call these members in the correct order causes a ProtocolViolationException exception when you attempt to get the request stream.

The credentials supplied for the FtpWebRequest object must have permission to perform the specified method. If not, the FTP command fails.

To determine the success or failure of a command, check the StatusCode and StatusDescription properties.
