I am trying to figure out an optimal way to parse the following DataStage job log into a C# object:

        Finished Job DS_JOB_NAME.RANDMONINVOCATIONID.

I've defined the following class:

public class JobLog
{
        public int EventId { get; set; }
        public DateTime Time { get; set; }
        public string Type { get; set; }
        public string User { get; set; }
        public string MessageId { get; set; }
        public string InvocationId { get; set; }
        public string Message { get; set; }
}

I was thinking to split the log by \r\n and check if the line contains the word Event Id then assign the value to the EventId property, and so on. My problem is with the message property, since it can include multiple lines. How should the logic be here?

    private void ParseLog()
    {
            var log = GetSampleLog()
                    .Split("\r\n");

            foreach (var line in log)
            {
                    if (line.Contains("Event Id:", StringComparison.InvariantCultureIgnoreCase))
                    {
                            var logObj = new JobLog
                            {
                                    EventId = int.Parse(line.Split(":")[1])
                            };
                    }
            }
    }

This is my solution :

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.IO;
using System.Globalization;

namespace ConsoleApplication51
{
    class Program
    {
        const string FILENAME = @"c:\temp\test.txt";
        static void Main(string[] args)
        {
            string line = "";
            StreamReader reader = new StreamReader(FILENAME);

            List<Event> events = new List<Event>();
            Event _event = null;
            string[] splitArray = null;
            Boolean getMessages = false;
            while ((line = reader.ReadLine()) != null)
            {
                line = line.Trim();
                if (line.Length > 0)
                {
                    if (line.StartsWith("Event Id"))
                    {
                        splitArray = line.Split(new char[] { ':' });
                        _event = new Event();
                        events.Add(_event);
                        _event.eventID = splitArray[1].Trim();
                        getMessages = false;
                        continue;
                    }
                    if (line.StartsWith("Time"))
                    {
                        int startOfDate = line.IndexOf(":") + 6;
                        string date = line.Substring(startOfDate).Trim();
                        _event.date = DateTime.ParseExact(date,"MMM dd HH:mm:ss yyyy", CultureInfo.InvariantCulture);
                        continue;

                    if (line.StartsWith("Type"))

                        _event.type = splitArray[1].Trim();
                        continue;

                    if (line.StartsWith("User"))

                        continue;
                    }
                    if (line.StartsWith("Message Id"))
                    {
