Select type object from json?

I have a problem with correct parse object from json query. I read something about JObject. Now i have two Model for example like Car and MotorBike. Query result is:

"Vehicles": 
 [
        {
            "Id": 1,
            "title": "test",
            "price": "4000",
            "type": "Car"
        },
        {
            "Id": 1,
            "title": "test",
            "price": "4000",
            "drivingLicenseCat" "A",
            "type": "MotorBike"
        }
    ]

how can i parse to custom model by type

How much control over the JSON do you have? If you are generating the JSON out of, say, web api correctly, it would come through more like:

"Vehicles": 
 [
        {
            "Id": 1,
            "title": "test",
            "price": "4000",
            "$type": "YourNamespace.Car, YourNamespace"
        },
        {
            "Id": 1,
            "title": "test",
            "price": "4000",
            "drivingLicenseCat" "A",
            "$type": "YourNamespace.MotorBike, YourNamespace"
        }
    ]

and then it would be automatically deserialized when you bring it in...

Ensure, in the model that you are serializing and sending out as JSON, that you mark it up like so:

[JsonProperty(ItemTypeNameHandling = TypeNameHandling.All)]

This will add the type names to the objects as they are serialized. I should also note, that this is with Newtonsoft as your Json library. I'm not sure about the built-in Json.
