想象一下賭博游戲，您必須匹配所有三個(gè)單詞才能獲得獎(jiǎng)勵(lì)。所以，如果你得到了，HHH你就會(huì)獲得獎(jiǎng)勵(lì)。我希望能夠代替W模仿任何字母。例如：HWW = HHH和HHW = HHH但WWW = WWW我該怎么做呢？

在將字符串與模式匹配之前，請(qǐng)將通配符更改為與任何內(nèi)容匹配的字符。像這樣：
// 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();
}
