Question

I’m using ServiceStack.Text to parse WorldWeatherOnline’s Marine Api.

When Deserialising the JSON the library parses the JSON incorrectly as you can see in the second column of the image below

This is a part the JSON (Snipped for brevity)

{
"data":{
  "nearest_area":[
     {
        "distance_miles":"36.8",
        "latitude":"53.965",
        "longitude":"0.456"
     }
   ]
 }
}

And this is the class i’m trying to deserialize it to

 public class Weather
{
    public NearestArea NearestArea { get; set; }

}

public class NearestArea
{
    public double? RetLatitude { get; set; }
    public double? RetLongitude { get; set; }
    public double? MilesFromReq { get; set; }
}

This is the bit of code that’s doing the deserialisation

Weather result = JsonObject.Parse(content).Object("data").ConvertTo(x=> new Weather{


                        NearestArea = x.Object("nearest_area").ConvertTo(n => new NearestArea{

                            MilesFromReq = Convert.ToDouble(n.Get("distance_miles")),
                            RetLatitude = Convert.ToDouble(n.Get ("latitude")),
                            RetLongitude = Convert.ToDouble(n.Get ("longitude"))

                        })

Can anyone spot the problem?

Below code should work…

var weather = ServiceStack.Text.JsonSerializer.DeserializeFromString<RootWeather>(content);


public class RootWeather
{
    public Weather data { get; set; }

}

public class Weather
{
    public List<NearestArea> nearest_area { get; set; }

}

public class NearestArea
{
    public string latitude { get; set; }
    public string longitude { get; set; }
    public string distance_miles { get; set; }
}
