AForge.net如何加到C#工程里边

首先用到e类库下载地址 然后引用e,e.Controls(这个是控件，可以添加到工具箱中),e.Imaging,e.Video,e.Video.DirectShow; 然后直接上代码 [csharp] view plain copy print?

private?FilterInfoCollection?videoDevices;??

private?VideoCaptureDevice?videoSource;??

public?int?selectedDeviceIndex?=?0;??

private FilterInfoCollection videoDevices;

? ? ? ?private VideoCaptureDevice videoSource;

? ? ? ?public int selectedDeviceIndex = 0; 下面是获取设备 [csharp] view plain copy print?

public?FilterInfoCollection?GetDevices()??

{??

try??

{??

//枚举所有视频输入设备??

videoDevices?=?new?FilterInfoCollection(FilterCategory.VideoInputDevice);??

if?(videoDevices.Count?!=?0)??

{??

LogClass.WriteFile("已找到视频设备.");??

return?videoDevices;??

}??

else??

return?null;??

}??

catch?(Exception?ex)??

{??

LogClass.WriteFile("error:没有找到视频设备！具体原因："?+?ex.Message);??

return?null;??

}??

}??

public FilterInfoCollection GetDevices()

??????? {

??????????? try

??????????? {

??????????????? //枚举所有视频输入设备

??????????????? videoDevices = new FilterInfoCollection(FilterCategory.VideoInputDevice);

??????????????? if (videoDevices.Count != 0)

??????????????? {

??????????????????? LogClass.WriteFile("已找到视频设备.");

??????????????????? return videoDevices;

??????????????? }

??????????????? else

??????????????????? return null;

??????????? }

??????????? catch (Exception ex)

??????????? {

??????????????? LogClass.WriteFile("error:没有找到视频设备！具体原因：" + ex.Message);

??????????????? return null;

??????????? }

??????? } 选择设备，然后连接摄像头 [csharp] view plain copy print?

<p>?///?<summary>??

///?连接视频摄像头??

///?</summary>??

///?<param?name="deviceIndex"></param>??

///?<param?name="resolutionIndex"></param>??

///?<returns></returns>??

public?VideoCaptureDevice?VideoConnect(int?deviceIndex?=?0,?int?resolutionIndex?=?0)??

{??

if?(videoDevices.Count?<=?0)??

return?null;??

selectedDeviceIndex?=?deviceIndex;??

videoSource?=?new?VideoCaptureDevice(videoDevices[deviceIndex].MonikerString);</p><p>????????????return?videoSource;??

}</p>??

<p>?/// <summary>

??????? /// 连接视频摄像头

??????? /// </summary>

??????? /// <param name="deviceIndex"></param>

??????? /// <param name="resolutionIndex"></param>

??????? /// <returns></returns>

??????? public VideoCaptureDevice VideoConnect(int deviceIndex = 0, int resolutionIndex = 0)

??????? {

??????????? if (videoDevices.Count <= 0)

??????????????? return null;

??????????? selectedDeviceIndex = deviceIndex;

??????????? videoSource = new VideoCaptureDevice(videoDevices[deviceIndex].MonikerString);</p><p>??????????? return videoSource;

??????? }</p> [csharp] view plain copy print?

//抓图，拍照，单帧??

public?void?GrabBitmap(string?path)??

{??

if?(videoSource?==?null)??

return;??

g_Path?=?path;??

videoSource.NewFrame?+=?new?NewFrameEventHandler(videoSource_NewFrame);??

}??

//抓图，拍照，单帧

public void GrabBitmap(string path)

? ? ? ?{

? ? ? ? ? ?if (videoSource == null)

? ? ? ? ? ? ? ?return;

? ? ? ? ? ?g_Path = path;

? ? ? ? ? ?videoSource.NewFrame += new NewFrameEventHandler(videoSource_NewFrame);

? ? ? ?} [csharp] view plain copy print?

void?videoSource_NewFrame(object?sender,?e.Video.NewFrameEventArgs?eventArgs)??

{??

Bitmap?bmp?=?(Bitmap)eventArgs.Frame.Clone();??

string?fullPath?=?path?+?"temp\";??

if?(!Directory.Exists(fullPath))??

Directory.CreateDirectory(fullPath);??

string?img?=?fullPath?+?DateTime.Now.ToString("yyyyMMdd?hhmmss")?+?".bmp";??

bmp.Save(img);??

void videoSource_NewFrame(object sender, e.Video.NewFrameEventArgs eventArgs)

? ? ? ?{

? ? ? ? ? ?Bitmap bmp = (Bitmap)eventArgs.Frame.Clone();

? ? ? ? ? ?string fullPath = path + "temp\";

? ? ? ? ? ?if (!Directory.Exists(fullPath))

? ? ? ? ? ? ? ?Directory.CreateDirectory(fullPath);

? ? ? ? ? ?string img = fullPath + DateTime.Now.ToString("yyyyMMdd hhmmss") + ".bmp";

? ? ? ? ? ?bmp.Save(img); [csharp] view plain copy print?

//如果这里不写这个，一会儿会不停的拍照，??

videoSource.NewFrame?-=?new?NewFrameEventHandler(videoSource_NewFrame);??

}??

//如果这里不写这个，一会儿会不停的拍照，

? ? ? ? ? ?videoSource.NewFrame -= new NewFrameEventHandler(videoSource_NewFrame);

? ? ? ?} 这样就完成了操作摄像头的工作 但是发现一个问题，如果要拍照得到的照片先要处理在保存，这里就有问题了，所以需要在界面前台中添加控件，医用e.Controls,然后添加到工具箱，然后将VideoSourcePlayer控件拖到窗体中，想要得到单张图像处理： Bitmap bmp = videoSourcePlayer1.GetCurrentFrame(); 这样就可以拿来处理了，e类库是非常的强大，这里只是冰山一角，文章不足之处还请大家多多指正，欢迎提出宝贵意见和建议。谢谢。。。
