int main()
{
   
   // Create a request for the Web page at www.contoso.com.
   WebRequest^ request = WebRequest::Create( L"http://www.contoso.com" );
   
   // This application doesn't want they proxy to be used so it sets
   // the global proxy to an empy proxy.
   IWebProxy^ myProxy = GlobalProxySelection::GetEmptyWebProxy();
   
   // Get the response.
   WebResponse^ response = request->GetResponse();
   
   // Display the response to the console.
   Stream^ stream = response->GetResponseStream();
   StreamReader^ reader = gcnew StreamReader( stream );
   Console::WriteLine( reader->ReadToEnd() );
   
   // Clean up.
   reader->Close();
   stream->Close();
   response->Close();
   return 0;
}

using System;
using System.Net;
using System.IO;
namespace Examples.Http
{
    public class TestGlobalProxySelection
    {
        public static void Main()
        {
            // Create a request for the Web page at www.contoso.com.
            WebRequest request = WebRequest.Create("http://www.contoso.com");
            // This application doesn't want the proxy to be used so it sets
            // the global proxy to an empty proxy.
            IWebProxy myProxy = GlobalProxySelection.GetEmptyWebProxy();
            GlobalProxySelection.Select = myProxy;
            // Get the response.
            WebResponse response = request.GetResponse();
            // Display the response to the console.
            Stream stream = response.GetResponseStream();
            StreamReader reader = new StreamReader(stream);
            Console.WriteLine(reader.ReadToEnd());
            // Clean up.
            reader.Close();
            stream.Close();
            response.Close();
        }
    }
}

Remarks

The Select property sets the proxy that all WebRequest instances use if the request supports proxies and no proxy is set explicitly using the Proxy property. Proxies are currently supported by FtpWebRequest and HttpWebRequest.
