Answer 1

Use:

  string[] arrstr = str.Reverse().Take(3).Reverse().ToArray();

In more recent versions of c# you can now use:

  string[] arrstr = str.TakeLast(3).ToArray();

Answer 2

It actually gets the number of elements and skip the remaining element from the total count and take the specified amount you can replace the 3 with N and use as method

string[] res = arrstr.Skip(Math.Max(0, arrstr.Count() - 3)).Take(3).ToArray();
