常用的通配符是星号(*)。它表示一个字符串中的零个或多个字符。
在以下示例中,星号用于匹配以m开头和以e结尾的单词-
@”\bt\S*s\b”
以下是完整的代码-
using System; using System.Text.RegularExpressions; namespace Demo { public class Program { private static void showMatch(string text, string expr) { MatchCollection mc = Regex.Matches(text, expr); foreach (Match m in mc) { Console.WriteLine(m); } } public static void Main(string[] args) { string str = "toss cross tacos texas"; Console.WriteLine("Matching words that start with 't' and ends with 's':"); showMatch(str, @"\bt\S*s\b"); } } }
输出结果
Matching words that start with 't' and ends with 's': toss tacos texas
