我可以用开关启动线程但不能结束它们

标签: c# multithreading switch-statement

我想根据运行程序的计算机的线程数启动一些线程。

我尝试过切换,但似乎无法结束线程。

这是我的主线程并且不起作用,它表示线程在第二个开关上脱离了上下文

我可以添加任何内容,还是应该使用其他方法?

答案 0 :(得分:1)

在尝试复杂的事情之前,你真的需要学习更多C#的基础知识。你有一个非常聪明和非常基本的代码的有趣组合。您似乎已经从其他地方复制并粘贴了许多内容。

您遇到的基本问题是您在第一个Thread Rolls6 = new Thread(Rolling2);语句的范围内声明了线程变量(switch (processorCount))。当谈到第二个时,这些变量不存在。您可以简单地将变量声明移到方法中更高的位置,以使它们对两者都可见,但这将是一个错误。调用Thread.Abort是一种非常糟糕的做法。你真的需要让线程正常终止的东西。

简而言之,你的线程应该看看它们什么时候结束,他们应该做出相应的反应。

此代码的基本方式是:

private static void Rolling(CancellationToken ct)
{
    while (true)
    {
        if (ct.IsCancellationRequested)
        {
            Console.WriteLine("Done with thread " + n);
            break;
        }
        /* Do Stuff Here, But Let The Code Loop Back */
    }
}

代码会不断检查CancellationToken以查看是否已设置IsCancellationRequested

这是如何彻底结束一个线程。

现在我已经摆脱了所有这些Rolling{n}方法,并用一个带有签名void Rolling(int n, int numberOfDie, int numberOfSides, double percent, CancellationToken ct)的方法替换它们。我试图摆脱全局变量(通常很糟糕)并遵循CancellationToken模式。

启动线程我已经获得了switch语句。线程创建现在看起来像这样:

        CancellationTokenSource[] ctss =
            Enumerable
                .Range(1, processorCount)
                .Select(n =>
                {
                    var cts = new CancellationTokenSource();
                    var t = new Thread(() =>
                        Rolling(n, numberOfDie, numberOfSides, percent, cts.Token));
                    t.Start();
                    return cts;
                })
                .ToArray();

要取消代码刚刚变为的所有线程:

        foreach (var cts in ctss)
        {
            cts.Cancel();
        }

...然后ct.IsCancellationRequested方法中的Rolling变为真,他们将自行关闭。

这就是你应该采取的方法。

这是您的完整代码:

private static System.Object lockThis = new System.Object();
public static ConsoleColor oldColor = Console.ForegroundColor;
private static int seed = Environment.TickCount;
private static readonly ThreadLocal<Random> random = new ThreadLocal<Random>(() => new Random(Interlocked.Increment(ref seed)));

    var x = GetValue("How Many Die Would You Like To Roll?", 1);
    if (x.HasValue)
    {
        var y = GetValue("How Many Sides Do You Want Each Die To Have?", 2);
        if (y.HasValue)
        {
            int numberOfDie = x.Value;
            int numberOfSides = y.Value;
            double percent = 100 * Math.Pow(1.0 / numberOfSides, numberOfDie);

            Console.WriteLine("With " + numberOfDie + ", " + numberOfSides + " Sided Die, You Have An " + percent + '%' + " Chance of Getting A Yahtzee With Any Given Roll");

            Console.WriteLine("Press Any Key To Commence");
            Console.ReadLine();

            int processorCount = System.Math.Min(Environment.ProcessorCount, 8);

            CancellationTokenSource[] ctss =
                Enumerable

                    .Select(n =>
                    {
                        var cts = new CancellationTokenSource();
                        var t = new Thread(() =>
                            Rolling(n, numberOfDie, numberOfSides, percent, cts.Token));
                        t.Start();
                        return cts;
