求一正式表达式的写法

[hb_bigsea]

求一正式表达式的写法例原 内容如下:

"CC":"421000","MM":"169"
"CC":"421001","MM":"179"
"CC":"421000","MM":"165"
"CC":"421000","MM":"161"
"CC":"421000","MM":"162"

要求:
依次分析出CC后面的值,

如:

("CC":"421000","MM":"169" 得到的值应为421000 )

如果正确得到了值为421000,那么如何一一到原内容中5个CC的值,并存入数组中,求高人解答

楼上的方法灵活性不强呀,
我想把
l.Add(a.Split(':')[1].Split(',')[0].Trim('"'));
把这一句换成
l.Add(a.Split('CC')[1].Split(',')[0].Trim('"'));
就开始报错了,
最好用一正则来匹配,如 "CC":"*", 这是我自己想的,但是正则不对,不会玩正则.请人继续指教

""CC"":""421000"",""MM"":""161""
""CC"":""421000"",""MM"":""162""
";

    string[] output = GetCC(input); // 这就是你要的数组
    foreach (string s in output)
    {
      Console.WriteLine(s);
    }
  }
  
  static string[] GetCC(string s)
  {
    List<string> l = new List<string>();
    foreach (Match m in Regex.Matches(s, @"""CC"":""([^""]*)"""))
    {
      l.Add(m.Groups[1].ToString());
    }
    return l.ToArray(); 
  }
}
