        More Info

        Regular expressions have their own syntax that is understood by regular expression engines. Those engines will throw an exception at runtime if they are given a regular expression that does not conform to that syntax.

        To avoid syntax errors, special characters should be escaped with backslashes when they are intended to be matched literally and references to capturing groups should use the correctly spelled name or number of the group.

        Negative lookaround groups cannot be combined with RegexOptions.NonBacktracking. Such combination would throw an exception during runtime.
