using System; using System.Text.RegularExpressions; namespace RegExApplication { public class Program { private static void showMatch(string text, string expr) { Console.WriteLine("The Expression: " + expr); MatchCollection mc = Regex.Matches(text, expr); foreach(Match m in mc) { Console.WriteLine("Found:" + m); } } public static void Main(string[] args) { string str = "My make"; Console.WriteLine("Matching words start with 'm' and ends with 'e':"); showMatch(str, @"\bmake\b"); } } }
