System.Windows.Forms.ListBindingHelper.GetListItemPropertiesByType C# (CSharp) Méthode

        private static PropertyDescriptorCollection GetListItemPropertiesByType(Type type, PropertyDescriptor[] listAccessors, int startIndex) {

            Type subType = listAccessors[startIndex].PropertyType;
            // subType is the property type - which is not to be confused with the item type.
            // For example, if a class Customer has a property of type Orders[], then Given:
            //        GetListItemProperties(typeof(Customer), PDForOrders)
            //      PDForOrders.PropertyType will be Array (not Orders)
            //

            //            GetListItemProperties(PDForOrders.PropertyType)  // this returns the shape of Orders not Array
            //        If there are more listAccessors, then we'll call

            startIndex = startIndex + 1;
