选择拍照的摄像头：

        private void Camlist()
        {
            videoDevices = new FilterInfoCollection(FilterCategory.VideoInputDevice);
            
            if (videoDevices.Count == 0)
            {
                MessageBox.Show("未找到摄像头设备");
            }
            foreach (FilterInfo device in videoDevices)
            {
                Cameralist.Items.Add(device.Name);
            }
        }

Cameralist是下拉框把摄像头列表添加到里面

 //选择要调用的摄像头，捕获视频并展示到videoSourcePlayer1
        private void Device_Click(object sender, EventArgs e)
        {
            Indexof = Cameralist.SelectedIndex;
            if (Indexof < 0)
            {
                MessageBox.Show("请选择一个摄像头");
                return;
            }
            this.pictureBox1.Visible = false;
            this.videoSourcePlayer1.Visible = true;
            //videoDevices[Indexof]确定出用哪个摄像头了。
            videoSource = new VideoCaptureDevice(videoDevices[Indexof].MonikerString);
            //设置下像素，这句话不写也可以正常运行：
            //videoSource.VideoResolution = videoSource.VideoCapabilities[Indexof];
            //在videoSourcePlayer1里显示
            videoSourcePlayer1.VideoSource = videoSource;
            videoSourcePlayer1.Start();
        }

videoSourcePlayer1是Aforge控件，网上能找到Dll导入到c#中，控件是dll拖到工具箱里才会有
