c# - 当被告知线程不休眠时

Question

我有一个在 C# 中创建线程的方法，该线程运行一个方法(CallCheckLogic - 如下所示)虽然我已经指定要发生 sleep (Thread.Sleep(60000);)方法(例如 ChecksObject.Check1Logic( )) 继续循环，就像 sleep 线程方法被忽略了一样。这对我来说没有逻辑意义，有人能解释为什么会发生这种行为吗？

预期结果: 创建了一个新线程，调用了 CallCheckLogic 方法，该方法本身调用 ChecksObject.Check1Logic >> ChecksObject.Check7Logic，然后是 Thread.Sleep(60000)；被调用，导致线程休眠 60 秒，然后运行循环并再次运行 CallCheckLogic。

private void StartCheckerThread()
{
    Thread t = new Thread(o =>{CallCheckLogic();});t.Start();
    running = true;
}

public void CallCheckLogic()
{
    Checks ChecksObject = new Checks();
    ChecksObject.Check1Logic();
    ChecksObject.Check2Logic();
    ChecksObject.Check3Logic();
    ChecksObject.Check4Logic();
    ChecksObject.Check5Logic();
    ChecksObject.Check6Logic();
    ChecksObject.Check7Logic();

    // This method / delegate parses the outfile of "temp" or rather the results of the tests and turns on / off the appropriate light on the GUI
    LightControlDelegate d1 = new LightControlDelegate(lightControl);
    this.BeginInvoke(d1);
    Thread.Sleep(60000);

    //LoopPorts();
}

ChecksObject.Check1Logic 方法:

public void Check1Logic()
{
    // clean up time! 
    File.Create("temp").Dispose();

    // lets grabs the info from the config!
    var lines = File.ReadAllLines("probe_settings.ini");
    var dictionary = lines.Zip(lines.Skip(1), (a, b) => new { Key = a, Value = b })
                          .Where(l => l.Key.StartsWith("#"))
                          .ToDictionary(l => l.Key, l => l.Value);

    // lets define variables and convert the string in the dictionary to int for the sock.connection method!

    int portno1;
    int.TryParse(dictionary["#PortNo1"], out portno1);

    // Convert hostname to IP, performance issue when using an invalid port on a hostname using the TcpClient class! 
    IPAddress[] addresslist = Dns.GetHostAddresses(hostname2);

    foreach (IPAddress theaddress in addresslist)
    {
        // Attempt to create socket and connect to specified port on host
        TcpClient tcP = new System.Net.Sockets.TcpClient();
        try
        {
            tcP.ReceiveTimeout = 1;
            tcP.SendTimeout = 1;
            tcP.Connect(theaddress, portno1);
            tcP.Close();
            StreamWriter sw = File.AppendText("temp");
            sw.Flush(); 
            sw.WriteLine("Check1=Success");
            sw.Close();
        }
        catch
        {
            StreamWriter sw = File.AppendText("temp");
            sw.WriteLine("Check1=Fail");
            sw.Close();
        }
    }
}

我在这里没有看到任何循环。您的 CallCheckLogic 方法被调用一次，然后它结束并且线程停止执行。 也许在您的 CheckXLogic 之一中存在无限循环，因此您的线程似乎一直在工作，但我可以说 Sleep 调用不太可能存在问题。

尝试在 Sleep 之前和之后添加断点，您将知道这行代码是否执行过。
