Examples

The following code example demonstrates calling this method.

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 );
   }
   else
   {
      Console::WriteLine( "Proxy for {0} is {1}", resource, 
         resourceProxy );
   }
}
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);
    }
    else
    {
        Console.WriteLine("Proxy for {0} is {1}", resource.ToString(),
            resourceProxy.ToString());
    }
}

Remarks

The GetDefaultProxy method reads the nondynamic proxy settings from the computer's Internet options 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 HttpClient.DefaultProxy property instead of the GetDefaultProxy method.

Note

This property is not supported on .NET Core.
