c#:converting地址到经纬度

Question

我试图使用此代码使用地理编码api将地址转换为经纬度。

protected void Button1_Click(object sender, EventArgs e)
{
    IGeocoder geocoder = new GoogleGeocoder() {  };
    Address[] addresses = geocoder.Geocode("#65/1 bangalore").ToArray();
    foreach (Address adrs in addresses)
    {
        Response.Write("address:"+adrs);
    }
}

我得到的答案是更详细的地址，而不是这个代码的经度和纬度.for示例。

address:Hari Om Trust Tapovana, 1, Bangalore, Karnataka 562123, India 

有人告诉我我需要做什么修改才能得到经度和纬度吗？

GoogleGeo编码器的代码是

 #region Assembly Geocoding.dll, v3.1.0.0
    // C:\Users\Admin\Documents\Visual Studio 2012\WebSites\learn1\Bin\Geocoding.dll
    #endregion

    using Geocoding;
    using System;
    using System.Collections.Generic;
    using System.Net;
    using System.Threading;
    using System.Threading.Tasks;

    namespace Geocoding.Google
    {
        public class GoogleGeocoder : IGeocoder, IAsyncGeocoder
        {
            public GoogleGeocoder();

            public string ApiKey { get; set; }
            public Bounds BoundsBias { get; set; }
            public BusinessKey BusinessKey { get; set; }
            public string Language { get; set; }
            public WebProxy Proxy { get; set; }
            public string RegionBias { get; set; }
            public string ServiceUrl { get; }

            public IEnumerable<GoogleAddress> Geocode(string address);
            public Task<IEnumerable<GoogleAddress>> GeocodeAsync(string address);
            public Task<IEnumerable<GoogleAddress>> GeocodeAsync(string address, CancellationToken cancellationToken);
            public IEnumerable<GoogleAddress> ReverseGeocode(Location location);
            public IEnumerable<GoogleAddress> ReverseGeocode(double latitude, double longitude);
            public Task<IEnumerable<GoogleAddress>> ReverseGeocodeAsync(double latitude, double longitude);
            public Task<IEnumerable<GoogleAddress>> ReverseGeocodeAsync(double latitude, double longitude, CancellationToken cancellationToken);

            protected class RequestState
            {
                public readonly CancellationToken? cancellationToken;
                public readonly HttpWebRequest request;

                public RequestState(HttpWebRequest request, CancellationToken? cancellationToken);
            }
        }
    }

Answer 1

啊..。其实很简单：

protected void Button1_Click(object sender, EventArgs e)
{
    IGeocoder geocoder = new GoogleGeocoder() {  };
    Address[] addresses = geocoder.Geocode("#65/1 bangalore").ToArray();
    foreach (Address adrs in addresses)
    {
        Response.Write("address:"+adrs.Coordinates);
    }
}

干杯

编辑:您只看到街道地址的原因是在循环中默认调用Address.ToString()。

请参考: Google有一个地理编码API，这个API在他们拥有Google数据的大多数位置上似乎运行得很好。

http://googlemapsapi.blogspot.com/2006/06/geocoding-at-last.html

它们提供在线地理编码(通过JavaScript)：

http://code.google.com/apis/maps/documentation/services.html#Geocoding

或后端地理编码(通过HTTP请求)：

直接

谷歌地图本身使用的数据通常是相同的。(请注意，这方面也有一些例外，例如联合王国或以色列，这些国家的数据来源不同，质量略有下降)
