Access List

The field that I access is of type List<EntityNetPlayer>, and the EntityNetPlayer class is internal (from an external assembly).

How do I make a List field to that class?

public static object GetAlivePlayers(object instance) =>
    instance.GetType()
    .GetField("AlivePlayers", BindingFlags.Instance |BindingFlags.NonPublic)
    .GetValue(instance)
