我試圖從谷歌地圖獲取座標時,用戶輸入的地址(現在)的2個值的城市和street.Having麻煩的反序列化來自谷歌地圖API的JSON字符串。一定很簡單,請幫我解釋我失蹤的事情。jsonconvert.deserializeobject返回null
這裏是JSON字符串: http://pasted.co/d9e7c1de
我需要的結果/幾何形狀/位置/緯度, 結果/幾何形狀/位置/ LNG信息
這裏是我的代碼:
public class Geometry
{
[JsonProperty("bounds")]
public Bounds bounds { get; set; }
[JsonProperty("location")]
public Location location { get; set; }
[JsonProperty("location_type")]
public string location_type { get; set; }
[JsonProperty("viewport")]
public Viewport viewport { get; set; }
}
public class Result
{
public List<AddressComponent> address_components { get; set; }
public string formatted_address { get; set; }
public Geometry geometry { get; set; }
public bool partial_match { get; set; }
public string place_id { get; set; }
public List<string> types { get; set; }
}
protected void Button1_Click(object sender, EventArgs e)
{
double coordinatesX = 0;
double coordinatesY = 0;
string APIKEY = "****************************";
string MyAdres = TextBox1.Text + "," + TextBox2.Text;
string stringpath;
stringpath = "https://maps.googleapis.com/maps/api/geocode/json?address=" + MyAdres + "&key=" + APIKEY;
WebClient Web = new WebClient();
string Jsonstring = Web.DownloadString(stringpath).ToString();
Result m = JsonConvert.DeserializeObject<Result>(Jsonstring);
coordinatesX = m.geometry.location.lat;
coordinatesY = m.geometry.location.lng;
}
這真的工作,我錯過了與根類:)解析 –
