Oh no, Timmy‘s received some hate mail recently but he knows better. Help timmy fix his regex filter so he can be awesome again!
using System; using NUnit.Framework; System.Text.RegularExpressions [TestFixture] public class Tests { [Test] public static void FixedTest() { Assert.AreEqual("You‘re awesome! timmy!", Kata.filterWords("You‘re Bad! timmy!")); Assert.AreEqual("You‘re awesome! timmy!", Kata.filterWords("You‘re MEAN! timmy!")); Assert.AreEqual("You‘re awesome!! timmy!", Kata.filterWords("You‘re UGLY!! timmy!")); Assert.AreEqual("You‘re awesome! timmy!", Kata.filterWords("You‘re horrible! timmy!")); Assert.AreEqual("You‘re awesome!! timmy!", Kata.filterWords("You‘re HiDeOuS!! timmy!")); Assert.AreEqual("You‘re awesomeish!! timmy!", Kata.filterWords("You‘re Meanish!! timmy!")); } }
主要是i的用法，

i |
Use case-insensitive matching. |
\b(?i)a(?-i)a\w+\b |
"aardvark", "aaaAuto" in "aardvark AAAuto aaaAuto Adam breakfast" |
using System; using System.Text.RegularExpressions; public class Kata { public static string filterWords(string phrase) { string pattern = @"(?i)bad|mean|ugly|horrible|hideous\b"; string replacement = "awesome"; Regex rgx = new Regex(pattern); return rgx.Replace(phrase, replacement); } }
