将两个字符串与替换字符匹配在一起

Question

想象一下赌博游戏，您必须匹配所有三个单词才能获得奖励。所以，如果你得到了，HHH你就会获得奖励。我希望能够代替W模仿任何字母。例如：HWW = HHH和HHW = HHH但WWW = WWW我该怎么做呢？

Answer 1

在将字符串与模式匹配之前，请将通配符更改为与任何内容匹配的字符。像这样：

  // this method change W wild-card character to a character that match anything

  private static bool MatchToString(string stringToMatch, string pattern) {

      Regex r = new Regex(pattern.Replace("W", "."));

      return r.Match(stringToMatch).Success;

  }

  static void Main() {

  // these are matches

  Console.WriteLine(MatchToString("HHH", "HWW"));

  Console.WriteLine(MatchToString("HHH", "HHW"));

  Console.WriteLine(MatchToString("WWW", "WWW"));

  Console.WriteLine(MatchToString("HHWH", "WWWW"));

  //these are doesn't

  Console.WriteLine(MatchToString("HHH", "HHK"));

  Console.WriteLine(MatchToString("HHH", "HKK"));

  Console.WriteLine(MatchToString("WWW", "ABC"));

  Console.ReadLine();

}
