Make a new type that essentially acts like another

    public struct ArrayInstanceData
    {
        public string Name;
        public bool IsDictionary;
        public Dictionary<string, DataValue> Data;
        public DataValue Value => Data["value"]; // non dictionary
        public ArrayInstanceData()
        {
            Name = "NULL"; // unset default
            IsDictionary = true; // default
            Data = new Dictionary<string, DataValue>();
        }
    }
    public struct ArrayContainer
    {
        public ArrayInstanceData[] Data;
    }

    public struct ArrayInstanceData
    {
        public string Name;
        public bool IsDictionary;
        public Dictionary<string, DataValue> Data;
        public DataValue Value => Data["value"]; // non dictionary
        public ArrayInstanceData()
        {
            Name = "NULL"; // unset default
            IsDictionary = true; // default
            Data = new Dictionary<string, DataValue>();
        }
    }
    public struct ArrayContainer
    {
        public ArrayInstanceData[] Data;
    }
