Assembly: System (in System.dll)
The property identifies the IWebProxy instance that communicates with the FTP server. The proxy is set by the system by using configuration files and the Internet Explorer Local Area Network settings. To specify that no proxy should be used, set to the proxy instance returned by the GlobalProxySelection.GetEmptyWebProxy method. For more information about automatic proxy detection, see Automatic Proxy Detection.
You must set before writing data to the request's stream or getting the response. Changing after calling the GetRequestStream, BeginGetRequestStream, GetResponse, or BeginGetResponse method causes an InvalidOperationException exception.
The FtpWebRequest class supports HTTP and ISA Firewall Client proxies.
