Question

所以我正在使用Kinect SDK制作一个应用程序，而且进展顺利！我正在尝试制作一个按钮拍照，但我希望延迟拍摄照片的代码让人们有时间摆出姿势。我尝试过使用System.Threading.Thread.Sleep（3000）;但是会发生的事情是整个事情都冻结了（是的，我知道这就是睡眠所做的......）并且无论如何都会使用第一帧。所以现在我正在尝试使用定时器和定时事件，但由于无法使其静态而不断出现错误（Kinect事情）。

public class Timer1
{
    private System.Timers.Timer aTimer;

    public void Main()
    {
        aTimer = new System.Timers.Timer(3000);
        //This is where the problem is. I'm getting "Cannot access a non-static member of outer type 'KinectButton.MainWindow' via nested type 'KinectButton.MainWindow.Timer1'
        aTimer.Elapsed += new ElapsedEventHandler(takepicture);
        aTimer.Interval = 1000;
        aTimer.Enabled = True;
    }
}

[private void takepicture(object sender, ElapsedEventArgs e)
{
    BitmapSource image = (BitmapSource)videoStream.Source;

    image.Save(DateTime.Now.ToString("ddMMyyyy HHmmss") + ".jpg", ImageFormat.Jpeg);
}

private void button7_Click(object sender, RoutedEventArgs e)
{
    //Here I'm also getting "'KinectButton.MainWindow.Timer1' does not contain a definition for 'Enabled'"
    Timer1.Enabled = true;
}

private void Timer1_Tick(object sender, EventArgs e)
{
    //Here I'm getting "'KinectButton.MainWindow.Timer1' does not contain a definition for 'Enabled'" again...
    Timer1.Enabled = false;
}

好吧，如果你们能提供帮助，请告诉我们！

我认为这是一个WPF应用程序？我想你会想要使用Windows.Threading.DispatcherTimer

Private timer As New Windows.Threading.DispatcherTimer

timer.Interval = New TimeSpan(0, 0, 0, 1)
AddHandler timer.Tick, AddressOf timer_Tick
timer.Start()

Private Sub timer_Tick(ByVal Sender As Object, ByVal e As EventArgs)
    'do something
End Sub

是的，我知道它的vb但它应该很容易转换

计时器使用Kinect SDK完成事件
