Question

I have a pattern to match with the string: string pattern = @’asc’ I am checking the SQL SELECT query for right syntax, semantics, … I need to say that in the end of the query string I can have ‘asc’ or ‘desc’. How can it be written in C#?

Answer 1

That’d look like

new Regex('asc$|desc$').IsMatch(yourQuery) 

assuming that you’re mandating that asc/desc is the end of the query. You could also do (?:asc|desc)$ which is a little cleaner with the single $, but less readable.
