API返回的部分JSON已由JSON.NET序列化，但并非全部

Question

我想这更多是我的代码问题，而不是JSON.NET问题，但我不确定我要去哪里。

我下面有以下用于将在此链接中找到的json数据序列化的类： https ://samples.openweathermap.org/data/2.5/weather?q=London,uk&appid =b6907d289e10d714a6e88b30761fae22

为了构造这个类，我使用了在google上找到的JSON到C＃生成器。

下面也是我用来将JSON数据提取并序列化为WeatherData对象的方法。

private string GetJsonFromWeb(string resource, string city)
{
    var request = new RestRequest(resource, Method.GET);
    request.AddParameter("q", city);
    request.AddParameter("APPID", "af5e6fd579e0ddb303afc1774487c77b");

    var fullUrl = client.BuildUri(request);
    Console.WriteLine("Full URL: " + fullUrl.AbsoluteUri);

    var response = client.Execute(request);
    string json = response.Content;
    return json;
}

private WeatherData SerializeJsonToWeatherData(string json)
{
    WeatherData weatherData = JsonConvert.DeserializeObject<WeatherData>(json);
    return weatherData;
}

这些方法可以成功工作，因为稍后可以在应用程序中使用JSON数据在GUI中显示信息。 但是，从API提取JSON后，JSON数据的MainData部分将设置为null。

class WeatherData
{
    public Coord Coord { get; set; }
    public List<Weather> Weather { get; set; }
    public string Base { get; set; }
    public MainData MainData { get; set; }
    public int Visibility { get; set; }
    public Wind Wind { get; set; }
    public Clouds Clouds { get; set; }
    public int Dt { get; set; }
    public Sys Sys { get; set; }
    public int Id { get; set; }
    public string Name { get; set; }
    public int Cod { get; set; }
}

public class Coord
{
    public double Lon { get; set; }
    public double Lat { get; set; }
}

public class Weather
{
    public int Id { get; set; }
    public string Main { get; set; }
    public string Description { get; set; }
    public string Icon { get; set; }
}

public class MainData
{
    public double Temp { get; set; }
    public int Pressure { get; set; }
    public int Humidity { get; set; }
    public double Temp_min { get; set; }
    public double Temp_max { get; set; }
}

public class Wind
{
    public double Speed { get; set; }
    public int Deg { get; set; }
}

public class Clouds
{
    public int All { get; set; }
}

public class Sys
{
    public int Type { get; set; }
    public int Id { get; set; }
    public double Message { get; set; }
    public string Country { get; set; }
    public int Sunrise { get; set; }
    public int Sunset { get; set; }
}

JSON属性称为main而不是mainData 。 JSON.Net找不到名为mainData ans的属性，因此不会填充MainData属性
