Question

How to get the underlying type of an Observable collection using reflection?

Consider following classes:

public class Order
{
    public int OrderID { get; set; }
    public string OrderDetails { get; set; }
}

public class Orders : ObservableCollection<Order>
{

}

Any Ideas?

You could use the GetGenericArguments method. Supposing you have an instance of Orders:

var orders = new Orders();
var type = orders.GetType().BaseType.GetGenericArguments()[0];
