推荐答案

双击事件。你可以改变间隔时间。

Double click event. you can change the interval time.

piCanv.PreviewMouseLeftButtonUp += new  MouseButtonEventHandler(Canvas_PreviewMouseLeftButtonUp);
int priviewTimestamp = -1;
const int iDoubleClickInterval = 500;
private void Canvas_PreviewMouseLeftButtonUp(object sender, MouseButtonEventArgs e)
{
    if (priviewTimestamp > 0)
    {
        if (e.Timestamp - priviewTimestamp < iDoubleClickInterval)
        {
            //this is the double click event
            //raise the double click event here or handle it here
        }
        priviewTimestamp = e.Timestamp;
    }
    else
        priviewTimestamp = e.Timestamp;
}
