How would you solve this? I want to return this collection:
Public Function GetShippingMethodsByCarrier(ByVal Carrier As ShippingCarrier) As List(of ?)
Return Carrier.ShippingMethods.Select(Function(x) New With {.ID = x.ID, .Name = String.Format("{0} {1}", Carrier.Name, x.Description)})
End Function
Thanks!!
You can’t return an anonymous type from a function like this because it has no name.
Since this is a public function is should have a well defined return type. Create a new class holding those two properties.
Its possible to return it if the return type is an inferred generic parameter, but that’s not what you want here. This is useful for LINQ where an anonymous type essentially gets passed through from a parameter to the result type, but not useful for what you’re doing.
You could also use a Tuple, but then you’d lose the property names. And it wouldn’t be extensible since adding a new property would break caller code. So I wouldn’t recommend that either.
