I am attempting to parse a json response and I'm not having any success.
This is my code:
public static DavisJsonData GetReadings()
{
var username = "test";
var password = "test";
var token = "001d0a00101010101010101";
var url = string.Format("http://someapi.com/my.json?user={0}&pass={1}&apiToken={2}", username, password, token);
var response = WebRequestClasses.GetResponse(url);
DataContractJsonSerializer jsonObjectPersonInfo = new DataContractJsonSerializer(typeof(DavisJsonData));
MemoryStream stream = new MemoryStream(Encoding.UTF8.GetBytes(response));
DavisJsonData result = (DavisJsonData)jsonObjectPersonInfo.ReadObject(stream);
return result;
}
And my DavisJsonData class:

I am getting this error when I attempt to run it:
An unhandled exception of type 'System.Runtime.Serialization.SerializationException' occurred in System.Runtime.Serialization.dll
Additional information: There was an error deserializing the object of type WeatherWizard.Davis.DavisJsonData. End element 'davis_current_observation' from namespace '' expected. Found element 'DID' from namespace ''.
I've not worked with json before so I would assume it is starting a new section? If so, how do I handle it?
davis_current_observationis a data object. You're trying to deserialize it into a string.
