C#에서 Thread 만들고 종료하기

PC기반제어프로그래밍(C#)/유틸리티 : 2016. 10. 23. 23:19

다른 스레드에서 Abort()를 호출하여 스레드를 종료하는 방법을 사용하면,
스레드의 작업이 완료 여부와 관계없이 스레드가 종료되어 리소스를 정리할 수도 없게 된다.

아래와 같은 방식으로 종료하자. (펌: MSDN)

using System;
using System.Threading;

public class Worker
{
    // This method will be called when the thread is started.
    public void DoWork()
    {
        while (!_shouldStop)
        {
            Console.WriteLine("worker thread: working...");
        }
        Console.WriteLine("worker thread: terminating gracefully.");
    }
    public void RequestStop()
    {
        _shouldStop = true;
    }
    // Volatile is used as hint to the compiler that this data
    // member will be accessed by multiple threads.
    private volatile bool _shouldStop;
}

public class WorkerThreadExample
{
    static void Main()
    {
        // Create the thread object. This does not start the thread.
        Worker workerObject = new Worker();
        Thread workerThread = new Thread(workerObject.DoWork);

workerThread.IsBackground = true;

        // Start the worker thread.
        workerThread.Start();
        Console.WriteLine("main thread: Starting worker thread...");

// Loop until worker thread activates. !..

// 작업자 스레드가 실행되기도 전에 Main함수가 이 스레드를 종료하지 않도록 하기 위해..!
while (!workerThread.IsAlive) ;

        // Put the main thread to sleep for 1 millisecond to
        // allow the worker thread to do some work:
        Thread.Sleep(1);

// Request that the worker thread stop itself:
workerObject.RequestStop();

        // Use the Join method to block the current thread
        // until the object's thread terminates.
        workerThread.Join();
        Console.WriteLine("main thread: Worker thread has terminated.");
    }
}
