无法将当前的 JSON object（例如 {“name”:“value”}）反序列化为 List 的类型 Collection

Question

I'm converting json to list of Model in C#, but this is making exception, In my Json response, i'm receiving GUID type, i don't know how to convert in model binding.

    client = new FireSharp.FirebaseClient(config);
    FirebaseResponse response = await client.GetAsync("Products/");
    var o = JsonConvert.DeserializeObject<Products>(response.Body);
    Products obj = response.ResultAs<Products>();
    var listOfProducts = response.ResultAs<List<Products>>();
    return View(listOfProducts);





  The below is my Json response,

    {"806CACEC-4D99-4EF5-935E-E4FAD8A6529C":{"categories":"Featured|Fish|Rice","productDescription":"New complete product\nThis is the test description to check how much space is taken by it.

And this is my model,

        public class Products
        {
            public string categories { get; set; }
            public string productDescription { get; set; }
            public string productImage { get; set; }
            public string productName { get; set; }
            public List<Sizes> sizes { get; set; }
            public string stockAmount { get; set; }
        }
        public class Sizes
        {
            public int goodFor { get; set; }
            public decimal price { get; set; }
            public string size { get; set; }
        }

Answer 1

A collection would be [{},{}] .

Your input is a single object.

It very common to wrap collections in an object before returning them (it's linked to security , search for 'top level json arrays').

---

You may need to create a wrapper object

public WithProducts {
public List<Products> Products { get; set; } // Guessing. See what the collection is called in the result
}
(...)

JsonConvert.Deserialise<WithProducts>(json);

---

Btw. It's good practice to use a singular noun for class names eg Product , Size so you don't end up with var oneProduct = new Products() {...} .

Answer 2

Because of the GUID key, the returned data can be converted to a Dictionary<string, Propducts> and the desired data extracted from the parsed dictionary

//...

FirebaseClient client = new FireSharp.FirebaseClient(config);
FirebaseResponse response = await client.GetAsync("Products/");
Dictionary<string, Products> data = response.ResultAs<Dictionary<string, Products>>();
List<Products>() listOfProducts = data.Select(kvp => kvp.Value).ToList();
return View(listOfProducts);

While the original data shown has one result. The above answer will also work when the object has multiple keys when the response has more than one item.
