string[] regexList = new string[] {
@"^(?[0-9A-Z])[ 0_]?(?[A-Z][0-9]) ?(COM(DTY)?|INDEX|IDX|IND|CURNCY|CUR|CLQ|ILQ|IDS)$",
@"^(?[0-9A-Z]{2,5}[A-Z][0-9]) ?(COM(DTY)?|INDEX|IDX|IND|CURNCY|CUR)$",
@"^(?[0-9A-Z]{2,5}[A-Z][0-9])$",
};
string externalId = "3ABZ9 COMDTY";
//测试例子
//A Z9 INDEX;AZ9 CUR;A_H9 IDX;A0H9COM;ABZ9 INDEX;3ABZ9 COMDTY;ABZ9;3ABZ9
foreach (string regexString in regexList)
{
if (Regex.IsMatch(externalId, regexString, RegexOptions.IgnoreCase))
{
Regex reg = new Regex(regexString, RegexOptions.IgnoreCase);
Match mc = reg.Match(externalId);
GroupCollection groups = mc.Groups;
string convertid = "";
foreach (string grn in reg.GetGroupNames())
{
if (grn.Contains("Ticker"))
convertid += groups[grn].Value;
}
Console.WriteLine(converted);
break;
}
}
以上例子将正则表达式中所有已经命名了的分组提取出来
