OData using ICollection<ITax> convert to strong type

Question

I'm using OData to make a post, but I need to pass a strongly typed object, in my main class, I have this property that contains a collection of interfaces

public ICollection<ITax> Taxes { get; set; }

Each interface is implemented by a tax type, as we can see here.

    public sealed class Tax1 : ITax
    {
        public decimal BaseTotalAmount { get; set; }

        public decimal TotalAmount { get; set; }
    }

    public sealed class Tax2 : ITax
    {
        public decimal BaseTotalAmount { get; set; }

        public decimal TotalAmount { get; set; }
    }

The problem I'm not getting through via JSON that makes the identification of each type of tax.

"Taxes": [
        {
            "BaseTotalAmount": 1.0,
            "TotalAmount": 1.0
        }
    ]

how can I set a field that identifies me that the object is of type Tax1 in json?

Answer 1

There is an easy approach, that might not help you, but as you didn't deliver much of a context it is what I can give you.

You just need one Tax class and in addition one enum. Let's say TaxType.

public ICollection<Tax> Taxes { get; set; }

public enum TaxType
{
    TaxType1 = 0,
    TaxType2 = 1
}

public sealed class Tax : ITax
{
    public TaxType Type { get; set; }

    public decimal BaseTotalAmount { get; set; }

    public decimal TotalAmount { get; set; }
}

Hope it helps
