Answer 1

Use GetSystemWebProxy to return what the system default proxy is.

    WebRequest.DefaultProxy = WebRequest.GetSystemWebProxy();

But every HttpWebRequest should automatically be filled out with this information by default. For example, the following snippet in a standalone console application should print the correct information on a system with a PAC file configured.

    HttpWebRequest myWebRequest=(HttpWebRequest)WebRequest.Create("http://www.microsoft.com");

    // Obtain the 'Proxy' of the  Default browser.  
    IWebProxy proxy = myWebRequest.Proxy;
    // Print the Proxy Url to the console.
    if (proxy != null)
    {
        Console.WriteLine("Proxy: {0}", proxy.GetProxy(myWebRequest.RequestUri));
    } 
    else
    {
        Console.WriteLine("Proxy is null; no proxy will be used");
    }

Answer 2

Use DefaultNetworkCredentials to return system proxy credentials.

request.Proxy.Credentials = System.Net.CredentialCache.DefaultNetworkCredentials;
