c# - 使用正则表达式从日志文件中提取数据

Question

我有以下日志文​​件

    10:12:28.571 INFO INFO McEvent (ExitWaitPostProcess) Stage: 2 
    10:12:28.571 INFO McReplay:StatusEvent: 0C0000004576656E74496E666F207631260000000A000000484C4D494E464F207631C0A80A0100007F0000010000010100000000000100000046658FDC5008000000303331333030303115000000

    10:12:28.571 INFO McReplay:StatusEvent verbose: event:03130001, msg:'Wait for post process',  submsg:'Exit Wait for post process Stage No2, Y-axis(Front Side), (Rear Lane),  ID:                '
    10:12:28.571 INFO INFO McEvent (ExitWaitPostProcess) Stage: 2 

我的正则表达式应该如何提取 McReplay 之后的内容，直到以时间戳开头的第一行。我在文件中出现了几次，我需要所有这些。

我想到了类似的东西

               new Regex(@"^(\d\d:\d\d:\d\d\.\d\d\d) INFO McReplay:(.*?)(\d\d:\d\d:\d\d\.\d\d\d)",
                           RegexOptions.Singleline | RegexOptions.Multiline);

似乎我对这部分有疑问(.*?)(\d\d:\d\d:\d\d\.\d\d\d)

我应该在这里解决什么？

这将找到所有出现

     List<string> results = new List<string>();
     MatchCollection mc = Regex.Matches("yourstring", "McReplay:(.+?)[0-9]{2}:[0-9]{2}:[0-9]{2}", RegexOptions.Singleline);
     foreach (Match item in mc)
     {
        results.Add(item.Result("$1"));
     }
