Mapping response objects(C#) - api

Question

I am consuming an API mehod and it returns response as of type Product and below is the response class structure.
Public class Product
{
public int Id;
public string Name;
public IList<Product> MasterProduct { get; set; }
}
The API result include the product attributes along with IList. Since this API cannot be consumed directly though our windows client we have a wrapper web API which consume this API, for this in the local API we have defined similar Product class. The issue I am facing is when trying to map the attibues of external API with local. Below is what I am trying to do.
response = Response.Result.Select(x => new Product
{
Id=x.Id,
Name=x.Name
MasterProduct = x.MasterProduct.Cast<MasterProduct>().ToList()//tried below
}).ToList();
but it fails with error as - Unable to cast object of type 'Api.Models.Product' to type 'App.DataContracts.Product'
The Masterproduct consist of hierarchal data .I am wondering if the approach I am taking is right or it has to be done through some method. Any suggestion or help would be appreciated.
Upon searching the web I came across some code where serpare method is being called to parse using Microsoft.Its.Data, but this was for single object where as in my case I have a List(Hierarchical).
Appreciate if someone can point to some linke/sampel to achive the same.

Trying serialization/deserialization would do. Below is the code
Perhaps trying serialization/deserialization would do.
if (response.Result != null)
{
var serializedResponse = JsonConvert.SerializeObject(Response.Result, Formatting.Indented);
response = JsonConvert.DeserializeObject<List<Product>>(serializedResponse);
}).ToList();
return response;
