Parsing CSV with Double Quotes using Regular Expressions, C#

I’m pretty sure that code like this adapts better to many conditions, but for a simple, fast way of parsing a CSV with values enclosed by double quotes, use Regex:

using System;
using System.Text.RegularExpressions;

public class Program 
{
	public static void Main()
	{
 	  Show("(\"[^\"]*\")","\"hola\",\"todo,el\",\"mundo\"");
	}

	public static void Show(string r, string s)
	{
	  var ms = Regex.Matches(s,r);
	  foreach(Match m in ms)
	  {
		Console.WriteLine("Groups[0]:{0}",m.Groups[0]);
		Console.WriteLine("Groups[1]:{0}",m.Groups[1]);
	  }	
	}	
}
