5/28/2002 (c) 2002 Orbonyx Corp. All Rights Reserved. At the end of episode 10, you will … Gain enough confidence with regular expressions that you start using them in.NET Understand why some of your trials did not produce the results that you predicted Know which classes in the.NET framework to use for pattern matching Know how to begin performing complex find/replace operations in VS IDE

5/28/2002 (c) 2002 Orbonyx Corp. All Rights Reserved. Regular Expressions; What are you talking about? Unix’s grep – “Global Regular Expression Print. Unix’s awk command – for pattern scanning and processing Also a large component of PERL.

5/28/2002 (c) 2002 Orbonyx Corp. All Rights Reserved. I still don’t know what you are talking about… Regular Expressions is a programmer’s way of saying “patterns”. Used for finding pattern matches in strings. Also used for find/replace operations.

5/28/2002 (c) 2002 Orbonyx Corp. All Rights Reserved. What we learned Regular Expressions go way beyond simple find and replace operations They can be used for validating input, reformatting data, capturing information Are fairly straight-forward to use in.NET … the trick is learning the RegEx language!
