Question

我有一个在C＃中创建一个运行方法的线程的方法（CallCheckLogic - 如下所示）虽然我已经指定了睡眠（Thread.Sleep（60000）;）方法（例如ChecksObject.Check1Logic（））保持循环，就像忽略睡眠线程方法一样。这对我来说没有逻辑意义，是否有人能够解释为什么会发生这种行为？

预期结果：创建一个新线程，调用CallCheckLogic方法，该方法本身调用ChecksObject.Check1Logic＆gt;＆gt; 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();
        }
    }
}

我在这里看不到任何循环。调用CallCheckLogic方法，然后结束，线程停止执行。也许你的一个CheckXLogic中存在无限循环，所以你的线程似乎一直在工作，但我可以说睡眠呼叫不太可能存在问题。

尝试在Sleep之前和之后添加断点，您将知道是否执行了这行代码。

被告知线程没有睡觉
