內容：在winform和opencvsharp的環境下，利用一個button事件控制相機（打開和關閉），并將相機獲取的圖片顯示在picturebox中。

VideoCapture capture;Mat frame;Bitmap image;private Thread camera;int isCameraRunning = 0;private void 打開相機_Click(object sender, EventArgs e){try{if (打開相機.Text.Equals("打開相機")){CaptureCamera();打開相機.Text = "關閉相機";isCameraRunning = 1;}else{capture.Release();打開相機.Text = "打開相機";isCameraRunning = 0;}}catch (NullReferenceException exception){MessageBox.Show(exception.Message);}}private void CaptureCamera(){camera = new Thread(new ThreadStart(CaptureCameraCallback));camera.Start();}private void CaptureCameraCallback(){frame = new Mat();capture = new VideoCapture();capture.Open(0);while (isCameraRunning == 1){bool read_success = capture.Read(frame);if (!read_success){MessageBox.Show("無法讀取攝像頭的幀！！！", "提示：");}else{ //防止狀態切換太快，讀到空值if (frame.Height == 0) continue;image = BitmapConverter.ToBitmap(frame);pictureBox1.Image = image;image = null;}//Cv2.WaitKey(20);}}
