c# - 如何将多个航路点发送到虚拟地球路由 Web 服务

Question

我正在尝试使用虚拟地球网络服务:

http://staging.dev.virtualearth.net/webservices/v1/routeservice/routeservice.svc?wsdl

返回停在多个点的车辆的总行程距离。

我的代码适用于具有 4 个航路点的旅程，但除此之外我会收到以下错误:

The maximum message size quota for incoming messages (65536) has been exceeded. To increase the quota, use the MaxReceivedMessageSize property on the appropriate binding element.

粗略的代码是:(C#控制台应用程序)

        Waypoint[] waypoints = new Waypoint[points.Length];

            if (pointIndex == 0)
                waypoints[pointIndex].Description = "Start";
            else if (pointIndex == points.Length)

            else

        routeRequest.Waypoints = waypoints;

        RouteOptions myRouteOptions = new RouteOptions();

                directions.Append(string.Format("Leg #{0}\n", legCount));

                foreach (ItineraryItem item in leg.Itinerary)
                {
                    instructionCount++;
                    directions.Append(string.Format("{0}. {1} {2}\n",
                        instructionCount, item.Summary.Distance, item.Text));
                    dayDistance += item.Summary.Distance;
                }
            }
            //Remove all Bing Maps tags around keywords.  
            //If you wanted to format the results, you could use the tags
            Regex regex = new Regex("<[/a-zA-Z:]*>",
              RegexOptions.IgnoreCase | RegexOptions.Multiline);
            results = regex.Replace(directions.ToString(), string.Empty);
        }
        else
            results = "No Route found";

        Console.WriteLine(results);
        Console.WriteLine(dayDistance);
    }

}

我不知道在哪里设置 MaxReceivedMessageSize 而且我读到它只适用于 Vista？!

帮助任何人？

我在这里找到了解决方案: link text

maxReceivedMessgeSize 在应用程序的 .config 文件中，即 web.config 或 app.config 等。
