c# - 如何模拟C#线程饥饿

Question

我正在尝试引发/导致线程饥饿，以便观察 C# 中的影响。

任何人都可以建议一个(简单的)应用程序，该应用程序可以创建以引起线程饥饿吗？

Answer 1

设置线程优先级和线程亲和度

worker 类(Class)

class PriorityTest
{
    volatile bool loopSwitch;
    public PriorityTest()
    {
        loopSwitch = true;
    }

    public bool LoopSwitch
    {
        set { loopSwitch = value; }
    }

    public void ThreadMethod()
    {
        long threadCount = 0;

        while (loopSwitch)
        {
            threadCount++;
        }
        Console.WriteLine("{0} with {1,11} priority " +
            "has a count = {2,13}", Thread.CurrentThread.Name,
            Thread.CurrentThread.Priority.ToString(),
            threadCount.ToString("N0"));
    }
}

并测试

class Program
{

    static void Main(string[] args)
    {
        PriorityTest priorityTest = new PriorityTest();
        ThreadStart startDelegate =
            new ThreadStart(priorityTest.ThreadMethod);

        Thread threadOne = new Thread(startDelegate);
        threadOne.Name = "ThreadOne";
        Thread threadTwo = new Thread(startDelegate);
        threadTwo.Name = "ThreadTwo";

        threadTwo.Priority = ThreadPriority.Highest;
        threadOne.Priority = ThreadPriority.Lowest;
        threadOne.Start();
        threadTwo.Start();

        // Allow counting for 10 seconds.
        Thread.Sleep(10000);
        priorityTest.LoopSwitch = false;

        Console.Read();
    }
}

代码主要取自 msdn另外，如果你有多核系统，你可能需要设置 thread affinity .您可能还需要创建更多线程才能看到真正的饥饿。
