2022-09-06 C#: Parse Log Data File

  • I need parse the data from log file, and the data is splited by comma as follows:

Solution

  • File open

    13
    14
    15
    16
    17
    18
    private void Task_OpenLogFile(int idx_EventLog)
    {
        fileName = @".\event_log_feed_"+ (idx_EventLog+1).ToString("D02") + ".csv";
        try
        {
            sr = File.OpenText(fileName);
            VAR_EventLogString = sr.ReadLine(); // 01
            listBox_EvenlogTestItems.Enabled = false; // 不可被點擊
        }
        catch (Exception e)
        {
            // 無法找到 File
            VAR_EventLogState = 0; // Start Send Event Log
            VAR_EventLogCount = 0; // Counter set to zero
            timer_EventLog.Enabled = false; // Enable Timer
            richTextBox_Log.AppendText(fileName + " not exist.\n");
        }
    }
  • Read a line from file
    1
    2
    3
    4
    5
    6
    7
    8
    private int Task_ReadOneEventAndParseData()
    {
        //string str= String.Empty;
        if ((VAR_EventLogString = sr.ReadLine()) == null)
          return (0); // Success
        //richTextBox_Log.AppendText(VAR_EventLogString+"\n");
        return (1);
    }
  • Parse the data and change the corresponed data type from string
