vb 2012 use regex to substitute specific key words with specific replacements RRS feed

  • Question

  • I am creating a VB 2012 application in which I have a two-dimensional array containing a collection of specific (but case-insensitive) key words with their replacement words.  I also have a very large series of String variables which I read sequentially from a .CSV file.

    What I want to do is to efficiently parse each String variable searching for any occurrence(s) of the Key words held in the array and substituting with their replacement.

    I know I can use "standard" VB code to do this but my instinct tells me that using Regular Expressions might be far more efficient.

    Never having attempted to use Regular Expressions before, but having just spent several hours attempting to research the subject online, I know I need some help, please.

    Any advice or guidance will be gratefully received.
