基本上，我有两个情节提要，其中一个用于情节提要和其他用于面板.我想在面板输入和面板输出之间等待几秒钟.

在面板中，我有一个完成的事件处理程序，该事件处理程序执行thread.sleep

请紧记，完成的事件得到

如何在不阻止所有内容的情况下等待动画?

Hi,

I'm trying to implement a way of waiting for an storyboard to stop, without blocking the whole app.

Basicly i have two storyboards, one for panels in and other for panels out. I want to wait a couple of seconds between the panels in and the panels out.

In the panels in i have a completed event handler that does thread.sleep

Strangly, the completed event gets triggered before the animation as really reached its end and everything gets blocked.

How can i make a wait without blocking everything?

Thx

Nuno

推荐答案

尝试使用此方法:

Try using this method:

私有 无效 收益( 长 刻度)

private void Yield(long ticks)

{

// 注意:刻度为100纳秒

    // Note: a tick is 100 nanoseconds

长 dtEnd = DateTime .Now.AddTicks(ticks).Ticks;

    long dtEnd = DateTime.Now.AddTicks(ticks).Ticks;

而 ( DateTime .Now.Ticks< dtEnd)

    while (DateTime.Now.Ticks < dtEnd)

{

this .Dispatcher.Invoke(DispatcherPriority.背景(DispatcherOperationCallback) 委托 ( 对象 未使用){ 返回 null ;}， null );

        this.Dispatcher.Invoke(DispatcherPriority.Background, (DispatcherOperationCallback)delegate(object unused) { return null; }, null);

}

}
