为什么以下代码会导致：

“ the”有1个匹配项

并不是：

“ the”有3个匹配项

using System;
using System.Text.RegularExpressions;
namespace TestRegex82723223
{
    class Program
    {
        static void Main(string[] args)
        {
            string text = "C# is the best language there is in the world.";
            string search = "the";
            Match match = Regex.Match(text, search);
            Console.WriteLine("there was {0} matches for '{1}'", match.Groups.Count, match.Value);
            Console.ReadLine();
        }
    }
}

回答：

string text = "C# is the best language there is in the world.";
string search = "the";
MatchCollection matches = Regex.Matches(text, search);
Console.WriteLine("there was {0} matches for '{1}'", matches.Count, search);
Console.ReadLine();
