 DoubleAnimation 漸隱漸現動畫     （如果不需要動畫，只想用這個介面顯示的框架，只需要把ChangeFrmMain方法裡面的程式碼                換成   this.frmMain.Navigate(content);  就可以了    frmMain 是一個Frame控制元件

        private void ChangeFrmMain(object content)
        {
            this.content = content;
            try
            {
                if (Content != null)
                {
                    this.IsHitTestVisible = false;
                    DoubleAnimation da = new DoubleAnimation(0.3d, new Duration(TimeSpan.FromMilliseconds(300)));
                    da.Completed += FadeOutCompleted;
                    this.BeginAnimation(OpacityProperty, da);
                }
            }
            catch
            {

            }
        }

        private void FadeOutCompleted(object sender, EventArgs e)
        {
            (sender as AnimationClock).Completed -= FadeOutCompleted;

            this.IsHitTestVisible = true;

            Dispatcher.BeginInvoke(DispatcherPriority.Loaded,
                (ThreadStart)delegate ()
                {
                    DoubleAnimation da = new DoubleAnimation(1.0d, new Duration(TimeSpan.FromMilliseconds(200)));
                    this.BeginAnimation(OpacityProperty, da);
                });

            this.frmMain.Navigate(content);
        }
