如何从经度和纬度中获取国家/地区名称 [英] how to get country name from latitude and longitude

问题描述

如何使用C#从纬度和经度中获取国家/地区名称? 我正在使用Bing.Map API

How can i get the country name from latitude and longtitude using c#? Im using the Bing.Map API

Location location12 = new Location(location.Latitude, location.Longitude);
MapLayer.SetPosition(pin, location12);
Map.Children.Add(pin);
string placeName = GetPlaceNameForCoordinates(location.Latitude, location.Longitude);   

推荐答案

您将要使用某种反向地理编码API.例如:

You'll want to use a reverse geocoding API of some kind. For example:

• Bing Maps API (网络服务)
• Google地理编码API
• Geonames API

• The Bing Maps API (the webservice)
• The Google Geocoding API
• The Geonames API

如果您已经在使用Bing.Maps SDK，则应使用Map.SearchManager属性获取

If you're already using the Bing.Maps SDK, you should use the Map.SearchManager property to get a SearchManager, and then use the ReverseGeocodeAsync method. In particular, as noted in comments, mixing and matching which API you use to show data via other SDKs may well violate the terms and conditions of both: be careful which technologies you use within a single application. (Even though this question gives sample code using the Bing Maps SDK, I've kept the list above in order to help others who may come with a slightly different context.)

例如:

var manager = map.SearchManager;
var request = new ReverseGeocodeRequestOptions(location) {
    IncludeEntityTypeFlags = ReverseGeocodeEntityType.CountryRegion
};
var response = await manager.ReverseGeocodeAsync(
    new ReverseGeocodeRequestOptions(location) { );
// Use the response

如果您决定使用Geonames API，也可以下载数据以供离线使用.

If you decide to use the Geonames API, the data can be downloaded for offline use too.
