[C#] Thread 종료하기

Abort를 호출하여 다른 스레드에서 스레드를 종료하는 방법을 사용하면

스레드의 작업이 완료되었는지 여부와 관계없이 스레드가 종료되어

리소스를 정리할 수도 없다.

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);

        // 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.");
    }
}
