Need to highlight the specific characters everytime it occur

Question

Hi all,

Im having the sentence “Anand had invited Anitha to look at his financial files any time she wanted". In this I have to highlight “an” in the given sentence. As of now I got an output of highlighting the “an” which occurs initially. But I cannot get highlighting the “an” which contains in throughout the sentence. Can anybody suggest is there any way to achieve my requirement without using looping statement in c#. If yes please share your valuable ideas. Thanks in advance.
