C# 中的正则简单例子

public static void Main()
{
      Regex rgx = new Regex(@"[S|s]et-[C|c]ookie: (?<cookieName>\w+)=(?<cookieValue>\w+).*");

      //// 全部匹配
      //MatchCollection mc = rgx.Matches(@"Set-Cookie: mm_lang=zh_CN; Domain=wx.qq.com; Path=/; Expires=Thu, 19-Jul-2018 12:14:16 GMT; Secure");
      //Console.WriteLine(mc.Count);
      //Match mth = mc[0];

      // 只匹配第一个
      Match mth = rgx.Match(@"Set-Cookie: mm_lang=zh_CN; Domain=wx.qq.com; Path=/; Expires=Thu, 19-Jul-2018 12:14:16 GMT; Secure");
      GroupCollection gc = mth.Groups;
      Console.WriteLine(gc[@"cookieName"].Value + gc[@"cookieValue"].Value + gc[@"domain"].Value);
}
