使用bing map API,我可以进行服务器端调用并获得给定城市的lat / long吗?
我可以使用JavaScript在客户端执行此操作,但在这种情况下我需要更强大的功能并希望使用服务器端。

发布此信息,以便更容易找到每个人的答案:
使用Bing Maps SOAP Services API(http://msdn.microsoft.com/en-us/library/cc980922.aspx)。它是一个公共Web服务,实现大多数Bing Maps API并提供静态映射(抱歉,没有来自用户的交互)。从提供的Microsoft SDK(稍加修改:将服务引用添加到项目后,运行此代码:
私有GeocodeResponse GeocodeAddress(字符串地址) { GeocodeRequest geocodeRequest = new GeocodeRequest();
// Set the credentials using a valid Bing Maps key
geocodeRequest.Credentials = new GeocodeService.Credentials();
geocodeRequest.Credentials.ApplicationId = BingMapsAPIKey;
// Set the full address query
geocodeRequest.Query = address;
// Set the options to only return high confidence results
ConfidenceFilter[] filters = new ConfidenceFilter[1];
filters[0] = new ConfidenceFilter();
filters[0].MinimumConfidence = GeocodeService.Confidence.High;
// Add the filters to the options
GeocodeOptions geocodeOptions = new GeocodeOptions();
geocodeOptions.Filters = filters;
geocodeRequest.Options = geocodeOptions;
// Make the geocode request
GeocodeServiceClient geocodeService = new GeocodeServiceClient("BasicHttpBinding_IGeocodeService");
GeocodeResponse geocodeResponse = geocodeService.Geocode(geocodeRequest);
return geocodeResponse;
}
您可以使用以下代码片段检查返回值:
result.Locations[0].Latitude.ToString();
result.Locations[0].Longitude.ToString();
