Regular Expression Extensions

RegexExtensions.cs

	}

	static public bool MatchThen(this Regex rgx, string input, Action<Match,dynamic> onSuccess, Action onFail = null)
	{
		var match = rgx.Match(input);

Sick and tired of evaluating Regex groups using the kludgy match.Groups["groupName"].Value syntax?
How about having to store your match and then check for success?
This extension method allows you to eliminate both issues with the MatchThen function.

Example usage:

var testString = "this is a pattern written by George";
var myRegex = new Regex(@"this is a pattern written by (?<personName>[\w\W]*?)$");
myRegex.MatchThen(testString, (match,result) => {
Console.WriteLine($"Turns out it was {result.personName}!");
}, () => {
// Note the fail method is optional and can be omitted
Console.WriteLine("No bueno!")
});
