I have following regular expression for postal code of Canada.

^[ABCEGHJKLMNPRSTVXY]{1}\d{1}[A-Z]{1} *\d{1}[A-Z]{1}\d{1}$

It is working fine but accepts only Capital letters. I want it work for both capital and small letters.

Hi Samuel,

Just use the option IgnoreCase,

So your regex creation could look like this

Regex r = new Regex(@"^[ABCEGHJKLMNPRSTVXY]\d[A-Z] *\d[A-Z]\d$", RegexOptions.IgnoreCase);

I removed also all your {1} because it is superfluous. Every item is per default matched once, no need to state this explicitly.
