Options changes are effective until the end of the enclosing group. See also the grouping construct ( ?imnsx-imnsx: ), which is a cleaner form. |
| ( ?# ) |
Inline comment inserted within a regular expression. The comment terminates at the first right parenthesis character. |
| # [ to end of line ] |
X-mode comment. The comment begins at an unescaped # and continues to the end of the line. ( Note that the "x" option or the RegexOptions.IgnorePatternWhitespace enumerated option must be activated for this kind of comment to be recognized. ) |
