以指定的时间间隔 c# 运行方法

我有一个按钮，按下该按钮时可以获取远程PC上各种Windows服务的状态。我想每分钟自动刷新此按钮，以便始终显示服务的最新状态。

我尝试设置计时器，但不断收到错误"跨线程操作无效：控制从创建它的线程以外的线程访问的'btnRefreshServices'

任何帮助表示赞赏

    private void btnRefreshServices_Click(
        object sender,
        EventArgs eventArgs)
    {
        this.btnRefreshServices.Enabled = false;
        // Setting up progress bar in a separate thread to update the progress bar
        // This is necessary so that the dialog doesn't freeze while the progress bar is reporting its progress
        this.prgbServiceStatus.Minimum = 1;
        this.prgbServiceStatus.Maximum = 11;
        this.prgbServiceStatus.Step = 1;
        this.prgbServiceStatus.Value = 1;
        this.prgbServiceStatus.Increment(1);
        this.prgbServiceStatus.PerformStep();
        var _backgroundWorker = new BackgroundWorker();
        _backgroundWorker.ProgressChanged += ProgressChanged;
        _backgroundWorker.DoWork += DoWork;
        _backgroundWorker.WorkerReportsProgress = true;
        _backgroundWorker.RunWorkerAsync();
        _backgroundWorker.RunWorkerCompleted += new  RunWorkerCompletedEventHandler(RunWorkerCompleted);
    }
    private void DoWork(
        object sender,
        DoWorkEventArgs doWorkEventArgs)
    {
        // Get the current status of each Windows service and reflect the progress in the progress bar
        // NOTE: If you add a new service, divide the number of services by 100 and update each call to report progress
        ((BackgroundWorker)sender).ReportProgress(15);
        CurrentStatus(
            this.grdResults,
            ServerA,
            ServiceName,
            RowIndexA);
        ((BackgroundWorker)sender).ReportProgress(25);
        CurrentStatus(
            this.grdResults,
            ServerB,
            ServiceNameB,
            RowIndexB);
        ((BackgroundWorker)sender).ReportProgress(35);

}

我为计时器使用了类似此代码的代码

    Timer myTimer = new Timer();
    myTimer.Elapsed += new ElapsedEventHandler(DisplayTimeEvent);
    myTimer.Interval = 1000; // 1000 ms is one second
    myTimer.Start();
    public static void DisplayTimeEvent(object source, ElapsedEventArgs e)
    {
       // code here will run every second
    }

使用Emile Pels代码，我能够解决我的问题。

    public frmServicesManager()
    {
        InitializeComponent();
        // The interval in milliseconds (1000 ms = 1 second)
        const double interval = 5000.0;
        // Create a new timer
        new System.Timers.Timer()
            {
                Enabled = true,
                Interval = interval
            }.Elapsed += TimerCallback;
    }
    private void TimerCallback(
        object sender, 
        ElapsedEventArgs elapsedEventArgs)
    {
        // SignalTime is now of type DateTime and contains the value indicating when the timer's Elapsed event was raised
        var _signalTime = elapsedEventArgs.SignalTime;
        // Create a new Action
        var _setButtonClick = new Action<DateTime>(dateTime => this.btnRefreshServices.PerformClick());
        // Check if we can access the control from this thread
        if (this.btnRefreshServices.InvokeRequired)
        {
            // We can't access the label from this thread,so we'll call invoke so it is executed from the thread the it was created on
            this.btnRefreshServices.Invoke(_setButtonClick, _signalTime);
        }
    }

myButton.Invoke(new Action<string>((text) => myButton.Text = text), "New button text");

//The interval in milliseconds (1000 ms = 1 second)
const double interval = 1000.0;
//Create a new timer
new System.Timers.Timer()
{
    Enabled = true, //Start it right away
    Interval = interval //Set the interval
}.Elapsed += TimerCallback; //Register a handler for the elapsed event

private void TimerCallback(object sender, System.Timers.ElapsedEventArgs e)
{
    const string baseString = "The event was raised at {0}";
    //signalTime is now of type DateTime and contains the value 
    //indicating when the timer's Elapsed event was raised
    var signalTime = e.SignalTime;
    //Create a new Action - delegate - which takes a string argument
    var setLabelText = new Action<DateTime>(dt =>
    {
        //If the amount of seconds in the dt argument is an even number,
        //set the timeLabel's forecolor to red; else, make it green
        timeLabel.ForeColor = dt.Second % 2 == 0 ? Color.Red : Color.Green;
        //Format the baseString to display the time in dt
        timeLabel.Text = string.Format(baseString, dt.ToLongTimeString());
    });
    //Check if we can access the control from this thread
    if (timeLabel.InvokeRequired) {
        //We can't access the label from this thread,
        //so we'll call invoke so it is executed from
        //the thread the it was created on
        timeLabel.Invoke(setLabelText, signalTime);
    }
    else {
        //The label's text can be set from this thread,
        //we'll just call the delegate without Invoke()
        setLabelText(signalTime);
    }
}

System.Windows.Forms.Timer myTimer = new System.Windows.Forms.Timer();
myTimer.Tick += DisplayTimeEvent;
myTimer.Interval = 1000; // 1000 ms is one second
myTimer.Start();
public static void DisplayTimeEvent(object source, EventArgs e)
{
   // code here will run every second
