我尝试用C＃解析Json数据，但我不知道如何从Task函数解析它。
这是我从Google地图获取Json数据的代码
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Net;
using System.Text;
using System.Threading.Tasks;
namespace PhoneApp3
{
class getJson
{
public getJson()
{
}
public async Task<string> RequestJsonFromGoogleMap(double lat, double lng)
{
//JSON String var
string returnString = "";
// server to POST to
string url = "https://maps.googleapis.com/maps/api/place/nearbysearch/json?location="
+ lat
+ ","
+ lng
+ "&radius=500&types=food&name=cafe&key=AIzaSyAOi7TswVYRlkqvZcQ88Qf9SUHODK67TR0";
// HTTP web request
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
using (var response = (HttpWebResponse)(await Task<WebResponse>.Factory.FromAsync(request.BeginGetResponse, request.EndGetResponse, null)))
{
using (var responseStream = response.GetResponseStream())
{
using (var sr = new StreamReader(responseStream))
{
returnString = await sr.ReadToEndAsync();
}
}
}
return returnString;
}
}
}
如果我运行代码
RequestJsonFromGoogleMap(21.0277644, 105.8341598);
我将按照以下方式获得String Json 那么如何获取每个位置的坐标？

答案 0 :(得分：1)
string jsonResult = await RequestJsonFromGoogleMap(21.0277644, 105.8341598);
然后将json转换为你需要的东西！
答案 1 :(得分：1)
您可以使用newtonsoft json反序列化器来反序列化字符串： Example
答案 2 :(得分：0)
我创建一个Json类，如下所示：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace PhoneApp4
{
class JsonSearchNearby
{
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 string reference { get; set; }
public string scope { get; set; }
public List<string> types { get; set; }
public string vicinity { get; set; }
}
public class RootObject
{
public List<object> html_attributions { get; set; }
public List<Result> results { get; set; }
public string status { get; set; }
}
}
}
但是，当我转换时，VS响应错误
'Newtonsoft.Json.JsonConvert.DeserializeObject（string）'的最佳重载方法匹配 有一些无效的论点
无法从'System.Threading.Tasks.Task'转换为'string'
字段初始值设定项无法引用非静态字段，方法或属性'PhoneApp4.MainPage.RequestJsonFromGoogleMap（double， 双）'
