当线程被告知这样做时，它没有睡觉

我有一个方法，在c#中创建一个线程，运行一个方法(CallCheckLogic -如下所示)虽然我已经指定了一个睡眠发生(thread . sleep(60000);)的方法(例如checksoobject . check1logic())保持循环，它就像睡眠线程方法被忽略。这对我来说没有逻辑意义，有人能解释一下为什么会发生这种行为吗?

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>> ChecksObject。Check7Logic然后是Thread.Sleep(60000);调用CallCheckLogic，导致线程休眠60秒，然后运行一个循环，CallCheckLogic再次运行。

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。

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();
        }
    }
