Is it impossible to use Generics dynamically? [duplicate]

Answer 1

You can't do it like that - the point of generics is mostly compile-time type-safety - but you can do it with reflection:

public Dictionary GenerateLists(List types)
{
    Dictionary lists = new Dictionary();

    foreach (Type type in types)
    {
        Type genericList = typeof(List<>).MakeGenericType(type);
        lists.Add(type, Activator.CreateInstance(genericList));
    }

    return lists;
}
