UWP：PointerMoved如果正在按下指针

Question

我目前正在尝试将我的WPF控件传输到UWP，并且陷入了PointerMoved事件。虽然我能够检查WPF中鼠标按钮的状态并仅在状态为真时执行我的代码，但我无法弄清楚UWP中的等效项。

我在WPF中有什么

private void MyControl_MouseMove(object sender, MouseEventArgs e)
{
  if (Mouse.LeftButton == MouseButtonState.Pressed)
    { 
       //...
    }
}

我想要的UWP

private void MyControl_PointerMoved(object sender, PointerRoutedEventArgs e)
{
   if("PointerIsBeingPressed")
     {
         //...
     }
}

赞赏每一个做出不同反应的答案或暗示！

Microsoft在documentation中提供了一个示例：

private void Target_PointerMoved(object sender, PointerRoutedEventArgs e)
{
    Windows.UI.Xaml.Input.Pointer ptr = e.Pointer;

    if (ptr.PointerDeviceType == Windows.Devices.Input.PointerDeviceType.Mouse)
    {      
        Windows.UI.Input.PointerPoint ptrPt = e.GetCurrentPoint(Target);
        if (ptrPt.Properties.IsLeftButtonPressed)
        {
            //Handle button press
        }        
    }
}
