使用Windows Phone 8 SDK的Bing Map SOAP Service问题 [英] Bing Map SOAP Service problem with Windows Phone 8 SDK

问题描述

Bing Map SOAP Service在Windows Phone 8上不起作用 - 启动SearchAsync时出现异常：

Bing Map SOAP Service doesn't work on Windows Phone 8 - exception when start SearchAsync:

        private void BingMapSearch(int searchCount, string keyWord)
        {
            try
            {
                SearchRequest searchRequest = new SearchRequest();
                searchRequest.Credentials = new Microsoft.Phone.Controls.Maps.Credentials();  

searchRequest.Credentials.ApplicationId = BingMapApplicationId;
StructuredSearchQuery ssQuery = new StructuredSearchQuery（）;
ssQuery.Location = _latitude.ToString（）+"，" + _longitude.ToString（）; ;
ssQuery.Keyword = keyWord;
searchRequest.StructuredQuery = ssQuery;

searchRequest.SearchOptions = new SearchOptions（）;
searchRequest.SearchOptions.Count = 25
searchRequest.SearchOptions.SortOrder = SortOrder.Distance;
SearchServiceClient searchService = new SearchServiceClient（）;
searchService.SearchCompleted + = new EventHandler< SearchCompletedEventArgs>（mapSearchService_SearchCompleted）;
searchService.SearchAsync（searchRequest）;
}
catch（exception ex）
{
MessageBox.Show（ex.Message，" Error"，MessageBoxButton.OK）;
}
}

void mapSearchService_SearchCompleted（object sender，SearchCompletedEventArgs e）
{
'''
}

searchRequest.Credentials.ApplicationId = BingMapApplicationId; StructuredSearchQuery ssQuery = new StructuredSearchQuery(); ssQuery.Location = _latitude.ToString() + "," + _longitude.ToString(); ; ssQuery.Keyword = keyWord; searchRequest.StructuredQuery = ssQuery; searchRequest.SearchOptions = new SearchOptions(); searchRequest.SearchOptions.Count = 25 searchRequest.SearchOptions.SortOrder = SortOrder.Distance; SearchServiceClient searchService = new SearchServiceClient(); searchService.SearchCompleted += new EventHandler<SearchCompletedEventArgs>(mapSearchService_SearchCompleted); searchService.SearchAsync(searchRequest); } catch (Exception ex) { MessageBox.Show(ex.Message, "Error", MessageBoxButton.OK); } } void mapSearchService_SearchCompleted(object sender, SearchCompletedEventArgs e) { ''' }

在Reference.cs中，它在线崩溃：

  base.EndInvoke（" Search"，_ args，result）

In Reference.cs, it crashes on line:
 base.EndInvoke("Search", _args, result)

public MyNameSpace.BingMapSearchServiceReference.SearchResponse EndSearch(System.IAsyncResult result) {
                object[] _args = new object[0];
                                MyNameSpace.BingMapSearchServiceReference.SearchResponse _result = ((MyNameSpace.BingMapSearchServiceReference.SearchResponse)(base.EndInvoke("Search", _args, result)));
                return _result;
            }

该代码适用于Windows Phone 7 / Emulator。 在Windows Phone 8上反序列化响应时，它看起来有问题。在WP8上解决此问题是否有任何解决方法？

The code works with Windows Phone 7/Emulator.  It looks it is having issues when deserializing the responses on Windows Phone 8. Any work around or fix for this issue on WP8?

推荐答案

您是如何设置网络服务的？ 您是否使用"添加服务引用..."创建了一个Web服务代理？向导或者您使用的是其他人放在一起的库吗？

How did you set up the web service?  Did you create a web service proxy using the "Add Service Reference..." wizard or are you using a library that someone else put together?

如果打开Visual Studio对象浏览器，加载项目，您会发现"类别"吗？ class？

If you open the Visual Studio Object Browser, with your project loaded, can you find that "Category" class?

奇怪的是它可以在WP7上运行但不适用于WP8 ...

It is weird that it would work on WP7 but not WP8...

你试过吗？网络捕获，例如：使用Fiddler，看两种情况下是否返回相同的SOAP有效负载？

Have you tried getting a network capture, ex: using Fiddler, to see if the same SOAP payload is returned in both cases?
