c# - Case insensitive Regex without using RegexOptions enumeration

Question

Is it possible to do a case insensitive match in C# using the Regex class without setting the RegexOptions.IgnoreCase flag?

What I would like to be able to do is within the regex itself define whether or not I want the match operation to be done in a case insensitive manner.

I would like this regex, taylor, to match on the following values:

• Taylor
• taylor
• taYloR

Answer 1

MSDN Documentation

(?i)taylor matches all of the inputs I specified without having to set the RegexOptions.IgnoreCase flag.

To force case sensitivity I can do (?-i)taylor.

It looks like other options include:

• i, case insensitive
• s, single line mode
• m, multi line mode
• x, free spacing mode
