c# - 如何从 lineX 读取到 lineY C#

Question

我正在尝试解析 .log 文件并得到如下所示的部分内容:

2014-03-31 13:20:42,046 DEBUG 4B414D00000001184917.GetConventionalDataTask - GetCompressedLogResponse received: GetCompressedLogResponse: Id = GetCompressedLog, LoggerType = LoadProfileLogger, NumberOfRegisters = 5, NewLogId = 3281, Info = HeadOfLoggerIncluded

 LogID          RealTimeClock Logger_Status Logger_Data_Quality EnergyA14 EnergyA23 
          [KamDateTimeStatus]      [NoUnit]            [NoUnit]     [kWh]     [kWh] 
------ ---------------------- ------------- ------------------- --------- ---------

  3265 02 2014-03-31T08:15:00          0000            00000000      0.17      0.00 
  3266 02 2014-03-31T08:30:00          0000            00000000      0.17      0.00 
  3267 02 2014-03-31T08:45:00          0000            00000000      0.17      0.00  

2014-03-31 13:20:42,049 DEBUG 4B414D00000001184917.GetConventionalDataTask - Updated timestamp for logger LoadProfileLogger with time 31-03-2014 12:20:42

如何获取 2 个 GetConventionalDataTask 行之间的行，以便程序知道开始读取包含 (GetCompressedLogResponse returned:) 的行到包含 (Updated timestamp for logger) 的行？

这是我能达到的目标:

public static bool IsLoggerStart(string text)
    {
        return text.Contains("GetCompressedLogResponse received:");
    }
    public static bool IsLoggerEnd(string text)
    {
        return text.Contains("Updated timestamp for logger");
    }
    public static string GetLoggerType(string text)
    {
        return GetSubStrings(text, "LoggerType = ", ", ").FirstOrDefault();
    }
    public static string GetNumberOfRegisters(string text)
    {
        return GetSubStrings(text, "NumberOfRegisters = ", ", ").FirstOrDefault();
    }
    public static string GetNewLogId(string text)
    {
        return GetSubStrings(text, "NewLogId = ", ", ").FirstOrDefault();
    }

以及我创建的对象:

class CompressedLogResponse
{
    public LoggerAnnounce LoggerAnnounce { get; set; }
    public List<int> LogID { get; set; }
    public List<DateTime> RealTimeClock { get; set; }
    public List<int> LoggerStatus { get; set; }
    public List<int> LoggerDataQuality { get; set; }
    public List<double> EnergyA14 { get; set; }
    public List<double> EnergyA23 { get; set; }
}
class LoggerAnnounce
{
    public string LoggerType { get; set; }
    public int NumberOfRegisters { get; set; }
    public int NewLogId { get; set; }

}

感谢您提供的任何帮助:)

Answer 1

您可以使用正则表达式获取2个GetConventionalDataTask之间的文本

string input = File.ReadAllText("C:/log.txt");
Match m = Regex.Match(input, @"GetConventionalDataTask\s-\s(.*).GetConventionalDataTask", RegexOptions.Singleline);
Console.WriteLine(m.Groups[1]);
