假设我们的字符串是-
string str = "The Shape of Water got an Oscar Award!";
使用以下正则表达式显示每个单词的首字母-
@"\b[a-zA-Z]"
这是完整的代码-
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(m); } } public static void Main(string[] args) { string str = "The Shape of Water got an Oscar Award!"; Console.WriteLine("Display first letter of each word!"); showMatch(str, @"\b[a-zA-Z]"); } } }
输出结果
Display first letter of each word! The Expression: \b[a-zA-Z] T S o W g a O A
