Actually you can do it pretty simple, since the list have a ForEach method and since you can pass in Console.WriteLine as a method group. The compiler will then use an implicit conversion to convert the method group to, in this case, an Action<int> and pick the most specific method from the group, in this case Console.WriteLine(int):

  var list = new List<int>(Enumerable.Range(0, 50));

  list.ForEach(Console.WriteLine);

Works with strings too =)

To be utterly pedantic (and I'm not suggesting a change to your answer - just commenting for the sake of interest) Console.WriteLine is a method group. The compiler then uses an implicit conversion from the method group to Action<int>, picking the most specific method (Console.WriteLine(int) in this case).
