在正则表达式中遍历字符串匹配的每个组名称

using System;
using System.Text.RegularExpressions;

public class Program

    {
        string input = "Hello, my name is John Doe. I live in New York.";
        string pattern = @"(?<name>\b\w+\b)";

        MatchCollection matches = Regex.Matches(input, pattern);

        foreach (Match match in matches)

                {
                    Console.WriteLine("Group Name: {0}, Value: {1}", group.Name, group.Value);
                }
