               This example explains how to get words by using delimiter ' ' and then reverse each word using String>reverse.
String.Split(new char{' '});//  Splits sentence  into an array words

Shared  Sub ReverseWordsInString()
          Dim original As String = "But,in a larger sense,we can not dedicate - 1
not consecrate = not consecrate - 1
          String()words=original.Split(New Char()
              " "c
          Dim i As Integer
          For  i = 0 To  words.Length- 1  Step i + 1
              Char()cWords = words(i).Reverse().ToArray()
              words(i) = New String(cWords)

          Dim word As String
          For Each word In words
