In Mono on OSX how do I get access to the current proxy?

问题

Both GetSystemWebProxy and DefaultWebProxy return null.

WebRequest.GetSystemWebProxy();
WebRequest.DefaultWebProxy;

If you use a recent version of monomac (or build it from source) then you should be able to call the static method CFNetwork.GetDefaultProxy (source, look at the end of the file) to get an IWebProxy instance that should match what OSX is using.
