How can I deserialization JSON in Windows Phone? - json

Question

The first JSON is look like this
The second JSON is look like this
How can I deserialize them? I have been follow this example but it's not working.
Here's my code.
protected override void OnNavigatedTo(NavigationEventArgs e)
{
var w = new WebClient();
Observable
.FromEvent<DownloadStringCompletedEventArgs>(w, "DownloadStringCompleted")
.Subscribe(r =>
{
var deserialized =
JsonConvert.DeserializeObject<List<Place>>(r.EventArgs.Result);
PlaceList.ItemsSource = deserialized;
});
w.DownloadStringAsync(
new Uri("http://mobiilivantaa.lightscreenmedia.com/api/place"));
//For 2nd JSON
//w.DownloadStringAsync(
//new Uri("http://mobiilivantaa.lightscreenmedia.com/api/place/243"));
}
These are classes for 1st JSON.
public class Place
{
public string id { get; set; }
public string title { get; set; }
public string latitude { get; set; }
public string longitude { get; set; }
public string www { get; set; }
}
public class RootObjectJSON1
{
public List<Place> Places { get; set; }
}
These are classes for JSON2
public class Address
{
public string street { get; set; }
public string postal_code { get; set; }
public string post_office { get; set; }
}
public class Image
{
public string id { get; set; }
public string filename { get; set; }
public string path { get; set; }
}
public class RootObjectJSON2
{
public string id { get; set; }
public string title { get; set; }
public string description { get; set; }
public string latitude { get; set; }
public string longitude { get; set; }
public string www { get; set; }
public string phone { get; set; }
public string email { get; set; }
public string contact_person { get; set; }
public Address address { get; set; }
public List<Image> images { get; set; }
}

Answer 1

it looks that you should be deserializing object RootObjectJSON1 or RootObjectJSON2, e.g.:
var deserialized = JsonConvert.DeserializeObject<RootObjectJSON1>(r.EventArgs.Result);
Also it seems that collection Places should be with lowercase p at beginning or you need to tell Json.NET that this property should be deserialized with different name, e.g.:
[JsonProperty(PropertyName="places")]
public List<Place> Places { get; set; }
Generally I tend to use arrays for deserialization (from my experience works better) so I'll suggest to rewrite it to this:
public class RootObjectJSON1
{
public Place[] places { get; set; }
}
There is very good tool named json2csharp available at http://json2csharp.com/ - just put sample of JSON there and it will spit out classes in C# (doesn't detect DateTime so you might need to change that).
