Passing Object to Array through Injection in .NET-CodePudding

I don't really know how to explain this but I'm having a really difficult time getting my code to work.

I'm working on a Web API in .NET and have this model in my code:

public class NewBasketDTO
    {

        public string Identifier { get; set; }
        public Array Items { get; set; }
    }

What I want to achieve here is that I want to be able to pass through objects to my Array like this in JSON format:

{
   identifier: "someidentifier",
   items: [
      { productId: 1, quantity: 1 },
      { productId: 3, quantity: 2 },
      { productId: 4, quantity: 1 }
   ]
}

But I'm having huge problems since in PostMan I'm getting this error:

System.NotSupportedException: The collection type 'System.Array' is abstract, an interface, or is read only, and could not be instantiated and populated. Path: $.items | LineNumber: 2 | BytePositionInLine: 12.

How do I pass objects to my public Array Itmes?

I've searched this up and found no sufficient answer, thanks in advance for any help

CodePudding user response：

System.Array is an abstract class and cannot be instantiated. You probably want to define Items as a List<ItemDTO> type.

public class ItemDTO
{
    public int ProductId { get; set; }
    public int Quantity { get; set; }
}

public class NewBasketDTO
{
    public string Identifier { get; set; }
    public List<ItemDTO> Items { get; set; }
}

Alternately you could use an array of ItemDTO:

public class NewBasketDTO
{
    public string Identifier { get; set; }
    public ItemDTO[] Items { get; set; }
}
