【问题描述】:
我有一个数据库,其中包含我需要获取经纬度的地址,因此我想遍历它们并使用 Google 地理编码来更新我的数据库。我不知道如何解析 JSOn 结果以获得我需要的东西:
var address = "http://maps.google.com/maps/api/geocode/json?address=1600+Amphitheatre+Parkway,+Mountain+View,+CA&sensor=false";
var result = new System.Net.WebClient().DownloadString(address);
GoogleGeoCodeResponse test = JsonConvert.DeserializeObject<GoogleGeoCodeResponse>(result);
我认为我可以简单地构建一个快速类并使用 JSON.Net 反序列化结果,它有点工作,但我认为我在我的类结构上吹了它:
public class GoogleGeoCodeResponse {
public string status { get; set; }
public geometry geometry { get; set; }
}
public class geometry {
public string location_type { get; set; }
public location location { get; set; }
}
public class location {
public string lat {get;set;}
public string lng {get;set;}
}
以下是 Google 返回的示例:
{
"status": "OK",
"results": [ {
"types": [ "street_address" ],
"formatted_address": "1600 Amphitheatre Pkwy, Mountain View, CA 94043, USA",
"address_components": [ {
"long_name": "1600",
"short_name": "1600",
"types": [ "street_number" ]
}, {
"long_name": "Amphitheatre Pkwy",
"short_name": "Amphitheatre Pkwy",
"types": [ "route" ]
}, {
"long_name": "Mountain View",
"short_name": "Mountain View",
"types": [ "locality", "political" ]
}, {
"long_name": "California",
"short_name": "CA",
"types": [ "administrative_area_level_1", "political" ]
}, {
"long_name": "United States",
"short_name": "US",
"types": [ "country", "political" ]
}, {
"long_name": "94043",
"short_name": "94043",
"types": [ "postal_code" ]
} ],
"geometry": {
"location": {
"lat": 37.4219720,
"lng": -122.0841430
},
"location_type": "ROOFTOP",
"viewport": {
"southwest": {
"lat": 37.4188244,
"lng": -122.0872906
},
"northeast": {
"lat": 37.4251196,
"lng": -122.0809954
}
}
}
} ]
}
我在这里缺少简单我知道的,有人吗?
