Question

我有这段代码：

foreach (var s in linesTxt)
{
    if (!myList.Contains(s))
    {
        myList.Add(s);
        if (!String.IsNullOrWhiteSpace(s))
        {
            Processor(s);
        }
    }
}

将每个详细信息放在一个.txt文件中，每行一个数据。

这是线程部分：

public void Processor(string Sample)
{
    //Process p = Process.GetCurrentProcess();
    ThreadStart Thread1 = new ThreadStart(() => firstFunc(Sample));
    ThreadStart Thread2 = new ThreadStart(() => secondFunc(Sample));
    ThreadStart Thread3 = new ThreadStart(() => thirdFunc(Sample));
    ThreadStart Thread4 = new ThreadStart(() => fourthFunc(Sample));
    ThreadStart Thread5 = new ThreadStart(() => fifthFunc(Sample));
    ThreadStart Thread6 = new ThreadStart(() => sixthFunc(Sample));
    ThreadStart Thread7 = new ThreadStart(() => seventhFunc(Sample));
    ThreadStart Thread8 = new ThreadStart(() => eightFunc(Sample));
    ThreadStart Thread9 = new ThreadStart(() => ninthFunc(Sample));
    ThreadStart Thread10 = new ThreadStart(() => tenthFunc(Sample));
    ThreadStart Thread11 = new ThreadStart(() => eleventhFunc(Sample));
    ThreadStart Thread12 = new ThreadStart(() => twelveFunc(Sample));
    ThreadStart Thread13 = new ThreadStart(() => thirteenFunc(Sample));
    Thread[] mainThread = new Thread[13];
    mainThread[0] = new Thread(Thread1);
    mainThread[1] = new Thread(Thread2);
    mainThread[2] = new Thread(Thread3);
    mainThread[3] = new Thread(Thread4);
    mainThread[4] = new Thread(Thread5);
    mainThread[5] = new Thread(Thread6);
    mainThread[6] = new Thread(Thread7);
    mainThread[7] = new Thread(Thread8);
    mainThread[8] = new Thread(Thread9);
    mainThread[9] = new Thread(Thread10);
    mainThread[10] = new Thread(Thread11);
    mainThread[11] = new Thread(Thread12);
    mainThread[12] = new Thread(Thread13);
    foreach (Thread myThread in mainThread)
    {
        //ThreadPool.SetMaxThreads(26, 26);
        //p.Refresh();
        //Console.WriteLine("Before start: {0}", p.Threads.Count);
        myThread.Start();
    }
}

firstFunc, secondFunc ....包含selenium c＃代码。

注意：我已尝试使用ThreadPool.SetMaxThreads但未成功。

例如，如果txt文件包含20个数据，那么我的电脑不会响应，但如果它只包含5个或更少，那么即使我遇到一些滞后也能正常工作。

我想要的是能够处理txt文件中的任意数量的数据。

更新

firstFunc包含：

                    var driverService1 = PhantomJSDriverService.CreateDefaultService();
                    driverService1.HideCommandPromptWindow = true;
                    var driver1 = new PhantomJSDriver(driverService1);
                    driver1.Navigate().GoToUrl("http://sample.com");
                    driver1.FindElement(By.Id("urlInput")).SendKeys(Domain);
                    driver1.FindElement(By.ClassName("convert-url")).Click();
                    var wait1 = new WebDriverWait(driver1, TimeSpan.FromSeconds(10));
                    wait1.Until(ExpectedConditions.ElementExists(By.XPath("//*[@class='alert alert-success alert-dismissible fade in']//p//input")));
                    System.Threading.Thread.Sleep(2000);
                    val1 = driver1.FindElement(By.XPath("//*[@class='alert alert-success alert-dismissible fade in']//p//input")).GetAttribute("value");
                    if (Results.InvokeRequired)
                    {
                        Results.Invoke(new MethodInvoker(delegate { Results.Items.Add(DomainSearch + " => " + "http://sample.com => " + val1); }));
                    }
                    driver1.Quit();
                    driverService1.Dispose();

您可以简单地使用Parallel：

var options = new ParallelOptions();
options.MaxDegreeOfParallelism = 5;

Parallel.Invoke(options,
  () => firstFunc(Sample),
  () => secondFunc(Sample),
  () => thirdFunc(Sample),
  ...
);

或Task.Factory：

ThreadPool.SetMaxThreads(5, 1000);

Task[] tasks = new Task[3] {
    Task.Factory.StartNew(() => firstFunc(Sample)),
    Task.Factory.StartNew(() => secondFunc(Sample)),
    Task.Factory.StartNew(() => thirdFunc(Sample)),
    ...
};

Task.WaitAll(tasks);
