Question

I am using Json.Net library to convert objects to json and back to objects.

I have an interface:

public interface IGoods
{
    List<IPen> Pens { get; set; }
    List<IPencil> Pencils{ get; set; }
    void Deserialize(String json);

}

implementation:

new public void Deserialize(String json)
    {
        JsonConvert.DeserializeObject<Goods>(json);
    }

The obvious error I got is: Could not create an instance of type Project.IPen. Type is an interface or abstract class and cannot be instantated.

How do I overcome this error?

Thanks!
