windows-phone-7 - Bing通过代理在window phone Emulator上映射溃败

Question

我使用下面给出的代码在 Bing Maps 上绘制路线。当系统直接连接到互联网时，它在模拟器上运行良好。但是当我在我公司的代理下的代码的倒数第二行时，它会抛出异常说：需要代理授权：407

BingMaps.RouteService.RouteServiceClient routeService = new BingMaps.RouteService.RouteServiceClient("BasicHttpBinding_IRouteService");
            BingMaps.RouteService.RouteRequest RouteReq = new BingMaps.RouteService.RouteRequest();
            RouteReq.Credentials = new BingMaps.RouteService.Credentials();
            RouteReq.Credentials.ApplicationId = ((ApplicationIdCredentialsProvider)Map.CredentialsProvider).ApplicationId;


            RouteOptions rOptions = new RouteOptions();
            rOptions.Mode = TravelMode.Driving;
            rOptions.Optimization = RouteOptimization.MinimizeDistance;
            RouteReq.Options = rOptions;
            RouteReq.Options.RoutePathType = BingMaps.RouteService.RoutePathType.Points;

            // Set the waypoints of the route to be calculated using the Geocode Service results stored in the geocodeResults variable.
            RouteReq.Waypoints = new System.Collections.ObjectModel.ObservableCollection<Waypoint>();
            foreach (Waypoint wp in WPList)
            {
                RouteReq.Waypoints.Add(wp);
            }
            //routeService.ClientCredentials = new System.ServiceModel.Description.ClientCredentials( new NetworkCredential("461167", "July@2012", "india");
            routeService.CalculateRouteAsync(RouteReq);
            routeService.CalculateRouteCompleted += new EventHandler<CalculateRouteCompletedEventArgs>(RouteService_CalculateRouteCompleted);

我知道我需要设置代理，但是我不知道如何设置。因为 RouteService 未配置接受代理凭据。

互联网在模拟器上也可以正常工作，我还在模拟器上设置了代理凭据。

请建议如何做到这一点，否则不可能，因为它没有使用模拟器的代理凭据，甚至没有使用系统上存储的凭据。
