Answer 2

1）直接来自Microsoft：How to match a pattern by using regular expressions and Visual C#

using System.Text.RegularExpressions;
Regex emailregex = new Regex("(?<user>[^@]+)@(?<host>.+)");
Match m = emailregex.Match(s);

2）您想要验证具有该格式的所有条目，还是只想获得“（任何曲目编号）”值？

首先，尝试搜索或使用Regular Expression Library

其次，试试这个：

Regex regex = new Regex(@"[^\d]+\d");
