JavaScriptSerializer How to Deserialize an identifier with space

I am having exactly the same problem as described here https://stackoverflow.com/questions/12565464/javascriptserializer-deserialize-an-identifier-with-space but as no one answered thought i'd try again,

API created by someone else in the form of

[{"AdvertId":"1234567","Price Original":"500","Sold":"False"}]

Application already uses a JavascriptSerilalization to populate the named properties on many other API's so do not want to change that really, but my class to hold this data can not have a property with a space in it "Price Original", and this can't be removed or replaced with an _ or something. Are there any methods that can be called to translate the string to something different?

Is there any solution to this or have I got to use JSON.net to deserialize, was some bits on DataContracts I read up on and these might be able to help but I can't seems to find out how to get this to work for my code, and would be nice to know that is possible without investigation this path.

Sample Class

Class Sample
{
    public int AdvertId { get; set; }
    public string Price Original { get; set; }
    public bool Sold { get; set; }
}

You can still use built-in types, but you'll need to use DataContractJsonSerializer instead of JavaScriptSerializer, and add the appropriate DataContract and DataMember attributes - the implementation is a bit different, but still pretty straightforward.

One thing - your Sold property is boolean, but your JSON sample has a string there - booleans are valid JSON types, so you can remove the quotes.

Some working code:

JSON:

[{"AdvertId":"1234567","Price Original":"500","Sold":false}]

C#:

var ser = new DataContractJsonSerializer(typeof(Sample[]));
using (var ms = new MemoryStream(Encoding.UTF8.GetBytes(JSON))) {
    Sample[] s = (Sample[])ser.ReadObject(ms);
}

[DataContract]
public class Sample {
    [DataMember]
    public int AdvertId { get; set; }

    [DataMember(Name = "Price Original")]
    public string PriceOriginal { get; set; }

    [DataMember]
    public bool Sold { get; set; }
}
