c# - 如何在 Windows 8.1 App 中使用地理编码？

Question

我需要从地址获取地理坐标。我试着走这条路: http://www.braincastexception.com/wp7-web-services-first-part-geocodeservice/但有一些错误。

1) 错误的论点:

GeocodeServiceClient geocodeService = new GeocodeServiceClient("BasicHttpBinding_IGeocodeService");

2) 事件不存在:

geocodeService.GeocodeCompleted += (sender, e) => geoCode_GeocodeCompleted(sender, e);

本文涉及 Windows Phone 7，但我使用的是 Windows 8.1 应用程序。也许 Windows 8.1 App 有另一种解决方案？我该怎么办？

Answer 1

要进行地理编码，请执行以下操作:

async void GetLocation(string address, Geopoint queryHintPoint)
{
    var result = await MapLocationFinder.FindLocationsAsync(address, queryHintPoint);

    // Get the coordinates
    if(result.Status == MapLocationFinderStatus.Success)
    {
        double lat = result.Locations[0].Point.Position.Latitude;
        double lon = result.Locations[0].Point.Position.Longitude;
    }
}

并反向地理编码:

async void GetLocationName(Geopoint yourLocation)
{
    var result = await MapLocationFinder.FindLocationsAtAsync(yourLocation);

    // Get the address
    if(result.Status == MapLocationFinderStatus.Success)
    {
        string address = result.Locations[0].Address.StreetNumber + result.Locations[0].Address.Street;
    }
}
