I’m getting back into using MonoTouch, and I tried using
HashSet<int, List<MyClass>>
I have a using for System.Collections.Generic, however I’m getting an error on the HashSet declaration, specifically I’m getting
The type or namespace name ‘HashSet`2’
could not be found. Are you missing a
using directive or an assembly
reference?
My code is having no issues with List, but adding in the HashSet I get this issue. Anyone have an idea as to the issue?
HashSet<>is a collection class supporting individual items, hence it only has one generic type parameter. The dual parameter mapping is aDictionary<TKey, TValue>.
