[ObsoleteAttribute("This method has been deprecated. Please use the proxy selected for you by default. http://go.microsoft.com/fwlink/?linkid=14202")]
public static WebProxy GetDefaultProxy()

Return Value

Type: System.Net.WebProxy

A WebProxy instance that contains the nondynamic proxy settings from Internet Explorer 5.5 and later.

The GetDefaultProxy method reads the nondynamic proxy settings stored by Internet Explorer 5.5 and later, and creates a WebProxy instance with those settings.

The GetDefaultProxy method does not pick up any dynamic settings that are generated from scripts run by Internet Explorer, from automatic configuration entries, or from DHCP or DNS lookups.

Applications should use the WebRequest.DefaultWebProxy property and the WebRequest.GetSystemWebProxy method instead of the GetDefaultProxy method.

The following code example demonstrates calling this method.

public static void CheckDefaultProxyForRequest(Uri resource)
    WebProxy proxy = (WebProxy) WebProxy.GetDefaultProxy();

    // See what proxy is used for resource.
    Uri resourceProxy = proxy.GetProxy(resource);

    // Test to see whether a proxy was selected.
    if (resourceProxy == resource)
        Console.WriteLine("No proxy for {0}", resource);
        Console.WriteLine("Proxy for {0} is {1}", resource.ToString(),
