在日常開發中，我們會經常遇到螢幕錄製的需求。在C#中可以通過Expression Encoder的SDK實現這樣的需求。首先需要下載Expression Encoder SDK，實現代碼：

        private ScreenCaptureJob job = null;        public MainWindow()        {            InitializeComponent();            job = new ScreenCaptureJob();            job.CaptureMouseCursor = false;        }        private void BtnPlay_Click(object sender, RoutedEventArgs e)        {            BtnPause.IsEnabled = true;            BtnStop.IsEnabled = true;            BtnPlay.IsEnabled = false;            if(job.Status == RecordStatus.NotStarted)            {                job.CaptureRectangle = Screen.PrimaryScreen.WorkingArea;                job.OutputPath = "D:/ScreenCapture";             }            job.Start();        }        private void BtnPause_Click(object sender, RoutedEventArgs e)        {            BtnPlay.IsEnabled = true;            BtnPause.IsEnabled = false;            job.Pause();        }        private void BtnStop_Click(object sender, RoutedEventArgs e)        {            BtnPlay.IsEnabled = true;            BtnPause.IsEnabled = false;            BtnStop.IsEnabled = false;            job.Stop();        }        private void OnClosing(object sender, System.ComponentModel.CancelEventArgs e)        {            if (job.Status == RecordStatus.Running)            {                MessageBoxResult result =                    System.Windows.MessageBox.Show("Capturing in Progress. Are You Sure You Want To Quit?", "Capturing",                    MessageBoxButton.YesNo);                if (result == MessageBoxResult.No)                {                    e.Cancel = true;                    return;                }                job.Stop();                job.Dispose();            }        }
