I would like to use the .Net Regex.Split method to split this input string into an array. It must split on whitespace unless it is enclosed in a quote.
Input: Here is "my string" it has "six matches"
Expected output:
What pattern do I need? Also do I need to specify any RegexOptions?

In order to use a literal ^ at the start or a literal $ at the end of a regex, the character must be escaped. Some flavors only use ^ and $ as metacharacters when they are at the start or end of the regex respectively. In those flavors, no additional escaping is necessary. It's usually just best to escape them anyway.
\s stands for “whitespace character”. Again, which characters this actually includes, depends on the regex flavor. In all flavors discussed in this tutorial, it includes [ \t\r\n\f]. That is: \s matches a space, a tab, a carriage return, a line feed, or a form feed.
The metacharacter “\s” matches spaces and + indicates the occurrence of the spaces one or more times, therefore, the regular expression \S+ matches all the space characters (single or multiple). Therefore, to replace multiple spaces with a single space.
No options required
Regex:
\w+|"[\w\s]*" C#:
Regex regex = new Regex(@"\w+|""[\w\s]*"""); Or if you need to exclude " characters:
Regex .Matches(input, @"(?<match>\w+)|\""(?<match>[\w\s]*)""") .Cast<Match>() .Select(m => m.Groups["match"].Value) .ToList() .ForEach(s => Console.WriteLine(s)); If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
