Console Writeline with threaded C#

Question

Hello I am trying to make threaded system for my console applications console output.

I did the KonsolStream like that.

public class KonsolStream
{
    ManualResetEvent _pauseEvent = new ManualResetEvent(true);
    ManualResetEvent _shutdownEvent = new ManualResetEvent(false);
    Thread _thread;

    private string _yazi;
    private int _tip;

    public int _Tip
    {
        get => _tip;
        set => _tip = value;
    }
    public string _Yazi
    {
        get => _yazi;
        set => _yazi = value;
    }

    public void KonsolaYaz()
    {
        switch (_Tip)
        {
            case 1:
                //uyarı
                Console.ForegroundColor = ConsoleColor.Red;
                Console.WriteLine(_Yazi);
                Console.ResetColor();
                IstemciDurdur();
                break;
            case 2:
                //başarı
                Console.ForegroundColor = ConsoleColor.Green;
                Console.WriteLine(_Yazi);
                Console.ResetColor();
                IstemciDurdur();
                break;
            case 3:
                //log
                Console.ForegroundColor = ConsoleColor.Yellow;
                Console.WriteLine(_Yazi);
                Console.ResetColor();
                IstemciDurdur();
                break;
            default:
                IstemciDurdur();
                break;
        }
    }
    private void IstemciDurdur()
    {
        _pauseEvent.Reset();
    }
    public void Start()
    {
        _thread = new Thread(DoWork);
        _thread.Start();
    }
    public void Resume()
    {
        _pauseEvent.Set();
    }

    public void DoWork()
    {
        while (true)
        {
            _pauseEvent.WaitOne(Timeout.Infinite);

            if (_shutdownEvent.WaitOne(0))
                break;

            KonsolaYaz();
        }
    }

}
public class KonsolMesaji : KonsolStream
{
    public KonsolMesaji(string yazi,int tip)
    {
        _Yazi = yazi;
        _Tip = tip;
    }
    public void Yaz()
    {
        Start();
    }
}

The Problem is when i start SistemBaslat() The messages are not synchronous. some times it starts with write message. and sometimes its start with Again I want to make the KonsolStream like, When i want to write some output to console i will use this stream lateron.

Answer 1

If you want the order of the message to be kept, you will have to use only one thread reading a single queue and have all the other threads push data into it. The good news is that your code will be much simpler; the bad news is that you have to have access to the queue wherever you want to log (you may create a static logger to ease this).

Edit: Instead of giving you the code, I suggest you check this link: Simple MultiThread Safe Log Class . You should find all your answers.

Answer 2

When reading your question I'm asking myself: do you just want to know about that for academical reasons (ie to learn how logging in a multi-threaded system works) or do you actually want to have multi-threaded logging in a productive application later on?

If your answer is the latter I would suggest using log4net as this can give you exactly what you want with just a little of configuration.

Update
After looking at the problem again I agree with PaulF that there's still a need to tie the results of the threads together and then write the different buckets to the console sequentially. In order to achieve this you could use a (static) instance of a class that holds all the logging messages for each thread (to distinguish the threads you can use the thread id as a key) and waits for the thread to finish, then writes all the log entries of this thread to the console sequentially.
