C# Regex "Verbose" like in Python

Question

In Python, we have the re.VERBOSE argument that allows us to nicely format regex expressions and include comments, such as

import re

ric_index = re.compile(r'''(
    ^(?P<delim>\.)    # delimiter "."
    (?P<root>\w+)$    # Root Symbol, at least 1 character
    )''',re.VERBOSE)

Is there something similar in C#?

Answer 1

You can use verbatim string (using @), which allow you to write:

var regex = new Regex(@"^(?<delim>\\.)     # delimiter "".""
                    (?<root>\\w+)$    # Root Symbol, at least 1 character
                    ", RegexOptions.IgnorePatternWhitespace);

Note the use of RegexOptions.IgnorePatternWhitespace option to write verbose regexes.
