.Net框架中是否有使用spinlock或spinwait的示例？

using System;
using System.Threading;

class Program
{
    static SpinLock spinLock = new SpinLock();

    static void Main()
    {
        // 创建多个线程并发执行
        for (int i = 0; i < 5; i++)
        {
            Thread thread = new Thread(DoWork);
            thread.Start();
        }

        Console.ReadLine();
    }

    static void DoWork()
    {
        bool lockTaken = false;
        try
        {
            // 尝试获取自旋锁
            spinLock.Enter(ref lockTaken);

            // 在临界区内执行操作
            Console.WriteLine($"Thread {Thread.CurrentThread.ManagedThreadId} entered the critical section.");
            Thread.Sleep(1000);
            Console.WriteLine($"Thread {Thread.CurrentThread.ManagedThreadId} exited the critical section.");
        }
        finally
        {
            // 释放自旋锁
            if (lockTaken)
                spinLock.Exit();
        }
    }
}
