Hi,

I like to get help on how to animate PictureBox moving to show car movement,I used timer and relocate the control box, but the animation is moving to fast.

Would any one help me to do that please..

Thanks in Advance.

推荐答案

避免使用计时器.而是使用单独的线程，使用System.Threading.Thread.Sleep定期更新坐标并稍有延迟，然后使用System.Windows.Forms.Control.Invoke或BeginInvoke通知UI线程.要使之平滑，请使用System.DataTime.Now或System.Diagnostics.Stopwatch在每个迭代中使用实时计算坐标.

关于调用:

您无法从非UI线程调用与UI相关的任何操作.相反，您需要使用System.Windows.Threading.Dispatcher的Invoke或BeginInvoke方法(对于Forms或WPF)或System.Windows.Forms.Control(仅对于Forms).

在我过去的答案中，您将找到有关其工作原理的详细说明和代码示例:
Control.Invoke()与Control.BeginInvoke() [ ^ ]，

现在，也许您根本不需要PictureBox.我不确定它是否对您有帮助.您可以使用自定义控件直接为事物设置动画.这是这样的:

Avoid using timer. Instead, use the separate thread, update the coordinates periodically with some delay using System.Threading.Thread.Sleep and notify UI thread using System.Windows.Forms.Control.Invoke or BeginInvoke. To make is smooth, use real time for calculation of coordinate in each iteration using System.DataTime.Now or System.Diagnostics.Stopwatch.

About invocation:

You cannot call anything related to UI from non-UI thread. Instead, you need to use the method Invoke or BeginInvoke of System.Windows.Threading.Dispatcher (for both Forms or WPF) or System.Windows.Forms.Control (Forms only).

You will find detailed explanation of how it works and code samples in my past answers:
Control.Invoke() vs. Control.BeginInvoke()[^],

Now, maybe you don''t need PictureBox at all. I''m not sure it helps you. You can animate things directly using custom Control. This is how:
