Question

我目前正在尝试在C＃中使用正则表达式：

Regex reg_gameinfo = new Regex(@"PokerStars Game #(?<HID>[0-9]+):\s+(?:HORSE)? \(?(?<GAME>Hold'em|Razz|7 Card Stud|Omaha|Omaha Hi/Lo|Badugi) (?<LIMIT>No Limit|Limit|Pot Limit),? \(?(?<CURRENCYSIGN>\$|)?(?<SB>[.0-9]+)/\$?(?<BB>[.0-9]+) (?<CURRENCY>.*)\) - (?<DATETIME>.*$)", RegexOptions.Multiline);
Match matchresults = reg_gameinfo.Match(rawtext);
Dictionary<string,string> gameinfo = new Dictionary<string,string>();
if (matchresults.Success)
{
     gameinfo.Add("HID", matchresults.Groups["HID"].Value);
     gameinfo.Add("GAME", matchresults.Groups["GAME"].Value);
     ...
}

我可以遍历matchresult.Groups GroupCollection并将键值对添加到我的gameinfo字典中吗？

Answer 1

（见这个问题：Regex: get the name of captured groups in C#）

您可以使用GetGroupNames：

Regex reg_gameinfo = new Regex(@"PokerStars Game #(?<HID>[0-9]+):\s+(?:HORSE)? \(?(?<GAME>Hold'em|Razz|7 Card Stud|Omaha|Omaha Hi/Lo|Badugi) (?<LIMIT>No Limit|Limit|Pot Limit),? \(?(?<CURRENCYSIGN>\$|)?(?<SB>[.0-9]+)/\$?(?<BB>[.0-9]+) (?<CURRENCY>.*)\) - (?<DATETIME>.*$)", RegexOptions.Multiline);
Match matchresults = reg_gameinfo.Match(rawtext);
Dictionary<string,string> gameinfo = new Dictionary<string,string>();

if (matchresults.Success)
    foreach(string groupName in reg_gameinfo.GetGroupNames())
        gameinfo.Add(groupName, matchresults.Groups[groupName].Value);

Answer 2

您可以将组名放入列表中并对其进行迭代。像

这样的东西

List<string> groupNames = ...
foreach (string g in groupNames) {
    gameinfo.Add(g, matchresults.Groups[g].Value);
}

但请务必检查该组是否存在。

通过C＃中的GroupCollection进行迭代
