In C#, Rotate a List to The Right by the specified numbers of places without using LINQ?

I am trying to rotate a List of items to the right by the specified numbers of places without using LINQ, how am I able to do this?

I think I am not understanding how to approach/solve this problem in particular. Here's what I have tried so far.

      public void Test(List<int> items, int places)
    {
        items.RemoveAt(places);
        items.Add(places);

    }
