   Get

      ' Return an array where each item is a key.

      '       ensures that the array is properly sized, in VB.NET
      '       declaring an array of size N creates an array with
      '       0 through N elements, including N, as opposed to N - 1
      '       which is the default behavior in C# and C++.
