在C#中同步线程访问和写入

class Program
{
    static object lockObject = new object();
    static int sharedVariable = 0;

    static void Main(string[] args)
    {
        // 创建两个线程
        Thread thread1 = new Thread(Increment);
        Thread thread2 = new Thread(Decrement);

        // 启动线程
        thread1.Start();
        thread2.Start();

        // 等待线程执行完成
        thread1.Join();
        thread2.Join();

        // 输出最终结果
        Console.WriteLine("Shared variable: " + sharedVariable);
    }

    static void Increment()
    {
        for (int i = 0; i < 100000; i++)
        {
            lock (lockObject)
            {
                sharedVariable++;
            }
        }
    }

    static void Decrement()
    {
        for (int i = 0; i < 100000; i++)
        {
            lock (lockObject)
            {
                sharedVariable--;
            }
        }
    }
}
