按下并释放按钮

Question

我希望按钮的功能如下：

if button is down(mouse button is hold down)
{
   bool trySmthing = true;
}

if button is up
{
   bool trySmthing = false;
}

我尝试了KeyUp和KeyDown个事件，但他们没有给出正确的结果。

显然，重点必须放在你的申请中;可以找到一个关于通过C＃中的.NET框架处理鼠标事件的教程here。记录为here的MouseDown事件和记录为here的MouseUp事件特别令人感兴趣。

Answer 2

这应该有所帮助：Micosoft Library for C# Mouse-events

void MouseUpHandler(Object sender, RoutedEventArgs args)
{
// This method is called whenever the PreviewMouseUp event fires.
}

void MouseDownHandler(Object sender, RoutedEventArgs args)
{
// This method is called whenever the PreviewMouseDown event fires.
}
