我正在做的是将从YAHOO天气获得的JSON转换为我的YahooWeatherModel
类。
反序列化后的json对象(我使用json.net)如下:
public class WeatherObject
{
public Location location { get; set; }
public List<Forecasts> forecasts { get; set; }
}
public class Location
{
public string country { get; set; }
public string city { get; set; }
}
public class Forecasts
{
public string Day { get; set; }
public string Date { get; set; }
public string Low { get; set; }
public string High { get; set; }
public int Text { get; set; }
public int Code { get; set; }
}
我需要的是将此对象转换为类似这样的内容:
public class YahooWeatherModel
{
public string Country { get; set; }
public string City { get; set; }
public string Day { get; set; }
public DateTime Date { get; set; }
public int Low { get; set; }
public int High { get; set; }
public int Text { get; set; }
public int Code { get; set; }
}
我使用Automapper进行映射。我了解如何在WeatherObject中为位置类部分创建地图:
var configuration = new MapperConfiguration(cfg => cfg
.CreateMap<WeatherObject, YahooWeatherModel>()
.ForMember(dest => dest.Country, opt => opt.MapFrom(map => map.location.country))
.ForMember(dest => dest.City, opt => opt.MapFrom(map => map.location.city))
但是如何将列表转换为不带列表的纯数据? 例如,在位置中,我有country = latvia,在城市中有riga,在天气预报中,我每个工作日有7个项目,还有其他天气数据。
我想要得到的是YahooWeatherModel列表,其中包含7个元素,包括国家,城市,日期,低,高...等信息

您可以使用LINQ做到这一点:
public void Convert(WeatherObject weatherObject)
{
IEnumerable<YahooWeatherModel> models = from forecast in weatherObject.forecasts
select new YahooWeatherModel
{
Country = weatherObject.location.country,
City = weatherObject.location.city,
Code = forecast.Code,
Date = System.Convert.ToDateTime(forecast.Date),
Day = forecast.Day,
High = System.Convert.ToInt32(forecast.High),
Low = System.Convert.ToInt32(forecast.Low),
Text = forecast.Text
};
}
