示例1: Main
//引入命名空间
using System;
using System.Collections.Generic;
using System.Text.RegularExpressions;
public class Example
{
public static void Main()
{
string pattern = @"(?<city>[A-Za-z\s]+), (?<state>[A-Za-z]{2}) (?<zip>\d{5}(-\d{4})?)";
string[] cityLines = {"New York, NY 10003", "Brooklyn, NY 11238", "Detroit, MI 48204",
"San Francisco, CA 94109", "Seattle, WA 98109" };
Regex rgx = new Regex(pattern);
List<string> names = new List<string>();
int ctr = 1;
bool exitFlag = false;
// Get group names.
do {
string name = rgx.GroupNameFromNumber(ctr);
if (! String.IsNullOrEmpty(name))
{
ctr++;
names.Add(name);
}
else
{
exitFlag = true;
}
} while (! exitFlag);
foreach (string cityLine in cityLines)
{
Match match = rgx.Match(cityLine);
if (match.Success)
Console.WriteLine("Zip code {0} is in {1}, {2}.",
match.Groups[names[3]],
match.Groups[names[1]],
match.Groups[names[2]]);
}
}
}输出：
Zip code 10003 is in New York, NY. Zip code 11238 is in Brooklyn, NY. Zip code 48204 is in Detroit, MI. Zip code 94109 is in San Francisco, CA. Zip code 98109 is in Seattle, WA.
