C# 从地址c获取纬度经度#

我正在使用geocoder的Web服务从地址、城市和州获取lat和long。当我使用下面的例子时，我没有得到lat和long。我做错什么了吗

请求地址：加利福尼亚州洛杉矶102街东1125号

这是我的密码：

private void GetLatLongFromAddress(string street, string city, string state)
{
    string geocoderUri = string.Format(@"http://rpc.geocoder.us/service/rest?address={0},{1},{2}", street, city, state);
    XmlDocument geocoderXmlDoc = new XmlDocument();
    geocoderXmlDoc.Load(geocoderUri);
    XmlNamespaceManager nsMgr = new XmlNamespaceManager(geocoderXmlDoc.NameTable);
    nsMgr.AddNamespace("geo", @"http://www.w3.org/2003/01/geo/wgs84_pos#");
    string sLong = geocoderXmlDoc.DocumentElement.SelectSingleNode(@"//geo:long", nsMgr).InnerText;
    string sLat = geocoderXmlDoc.DocumentElement.SelectSingleNode(@"//geo:lat", nsMgr).InnerText;

    Latitude = Double.Parse(sLat);
    Longitude = Double.Parse(sLong);
}

lat和long返回0。我也尝试添加邮政编码，但没有成功。有没有更好的Web服务可以提供最新的结果

提前谢谢。

我经常使用。您可以使用以下请求进行地理编码：

http://dev.virtualearth.net/REST/v1/Locations/CA/adminDistrict/postalCode/locality/addressLine?includeNeighborhood=includeNeighborhood&key=BingMapsKey

你可以看到它在使用中的一个例子

例如，您的地址：

http://dev.virtualearth.net/REST/v1/Locations/US/1125%20E.%20102nd%20Street,%20Los%20Angeles,%20CA?key=Ai9-KNy6Al-r_ueyLuLXFYB_GlPl-c-_iYtu16byW86qBx9uGbsdJpwvrP4ZUdgD

因此，给定地址的lat/long为（33.9，-118.2）

谷歌地图有一个返回lat/long的web服务API，适用于主要国家。有关示例，请参见。支持不同的输出格式，包括CSV、JSON等

我对geocoder.us不太熟悉，但谷歌地图在美国地址上确实很管用

编辑1： 有关支持的国家/地区的列表，请参阅

编辑2： 为了增强相关性，这里有一个针对您的地址的示例Google Maps API调用：

按地址获取纬度和经度-Microsoft BingMapsRESTToolkit 微软有一个官方软件可以帮助你轻松地使用它。为此，您需要安装BingMapsRESTToolkit

在这里，您有兴趣通过地址获取位置。您可以通过将

Query

属性设置为指定的地址，或将

address

属性设置为

address

或

SimpleAddress

的实例来指定地址

示例：

var request = new GeocodeRequest();
request.BingMapsKey = "Your Map Key";

request.Query = "The Postal address";

//OR
//request.Address = new SimpleAddress()
//{
//    CountryRegion = "The Country",
//    AddressLine = "The official street line of an address relative to the area",
//    AdminDistrict = "The subdivision name in the country or region for an address",
//    Locality = "The locality, such as the city or neighborhood", 
//    PostalCode = "The postal code",
//};

var result = await request.Execute();
if (result.StatusCode == 200)
{
    var toolkitLocation = (result?.ResourceSets?.FirstOrDefault())
        ?.Resources?.FirstOrDefault() as BingMapsRESTToolkit.Location;
    var latitude = toolkitLocation.Point.Coordinates[0];
    var longitude = toolkitLocation.Point.Coordinates[1];

    // Use latitude and longitude
}

更多信息：

var request = new GeocodeRequest();
request.BingMapsKey = "Your Map Key";

request.Query = "The Postal address";

//OR
//request.Address = new SimpleAddress()
//{
//    CountryRegion = "The Country",
//    AddressLine = "The official street line of an address relative to the area",
//    AdminDistrict = "The subdivision name in the country or region for an address",
//    Locality = "The locality, such as the city or neighborhood", 
//    PostalCode = "The postal code",
//};

var result = await request.Execute();
if (result.StatusCode == 200)
{
    var toolkitLocation = (result?.ResourceSets?.FirstOrDefault())
        ?.Resources?.FirstOrDefault() as BingMapsRESTToolkit.Location;
    var latitude = toolkitLocation.Point.Coordinates[0];
    var longitude = toolkitLocation.Point.Coordinates[1];

    // Use latitude and longitude
}

这不是一个真正的问题。这是一个关于Web服务的问题。请检查您的问题。这是关于一个特定的web服务，而不是c#。我试过你的代码GetLatLongFromAddress（“1125 E.102nd Street”，“Los Angeles”，“CA”）；它返回的纬度为33.944015，纬度为-118.255818。如何调用方法？此函数对我有效，返回正确的值。也许问题在于你的物体的纬度和经度？当你跨过它时，长跑和长跑的价值是什么？@AnthonyBlake，一个特定的、任意大小或发展水平的国家，我确信。作为回答，国家被添加为链接
