如果我们查看 json2csharp ，我们可以轻松生成用于响应Google Places查询的C#模型.

If we look at the documentation for the Google Places API, we can see the format of the JSON that a request to the API returns. By using json2csharp, we can then easily generate a C# model for the response to a Google Places query.

public class Location
{
    public double lat { get; set; }
    public double lng { get; set; }
}

public class Geometry
{
    public Location location { get; set; }
}

public class OpeningHours
{
    public bool open_now { get; set; }
    public List<object> weekday_text { get; set; }
}

public class Photo
{
    public int height { get; set; }
    public List<string> html_attributions { get; set; }
    public string photo_reference { get; set; }
    public int width { get; set; }
}

public class Result
{
    public Geometry geometry { get; set; }
    public string icon { get; set; }
    public string id { get; set; }
    public string name { get; set; }
    public OpeningHours opening_hours { get; set; }
    public List<Photo> photos { get; set; }
    public string place_id { get; set; }
    public double rating { get; set; }
    public string reference { get; set; }
    public string scope { get; set; }
    public List<string> types { get; set; }
    public string vicinity { get; set; }
}

public class PlacesApiQueryResponse
{
    public List<object> html_attributions { get; set; }
    public List<Result> results { get; set; }
    public string status { get; set; }
}

通过对Google Places API的简单HTTP请求，我们便可以使用 Json.NET .

With a simple HTTP request to the Google Places API, we can then deserialize the query results using Json.NET.

using (var client = new HttpClient())
{
    var response = await client.GetStringAsync(string.Format("https://maps.googleapis.com/maps/api/place/nearbysearch/json?location={0},{1}&radius=500&type=bar&key=YourAPIKey", latitude, longitude));
    var result = JsonConvert.DeserializeObject<PlacesApiQueryResponse>(response);
}
