c# - How to find multiple occurrences with regex groups?



Why does the following code result in:




there was 1 matches for 'the'





and not:




there was 3 matches for 'the'




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();
}
}
}

Answer



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();
