IEnumerable<T> interface and can be used easily in LINQ (without requiring any
ArrayList belongs to the days that C# didn't have generics. It's deprecated in favor of
List<T>. You shouldn't use
ArrayList in new code that targets .NET >= 2.0 unless you have to interface with an old API that uses it.
