在.NET框架中，C#是一种常用的编程语言，用于开发各种应用程序，包括Windows桌面应用。WinForms是C#中用于创建图形用户界面（GUI）的库，它提供了丰富的控件和功能来构建桌面应用。本教程将详细介绍如何在C# WinForms应用中调用电脑摄像头，以实现基本的视频捕捉和显示功能。你需要引入必要的库。在C#项目中，添加对`System.Drawing`和`System.Windows.Forms`命名空间的引用，它们包含了处理图像和用户界面的基础类。同时，为了访问摄像头，还需要引用`System.Media`和`AForge.Video`库。`AForge.Video`是一个开源库，提供了与视频设备交互的功能。 1. **安装AForge库** - 在Visual Studio中，右键点击项目，选择“管理NuGet程序包”。 - 搜索“AForge.Net”，安装该包。这将自动安装所有必要的依赖项，如AForge.Video。 2. **创建WinForms界面** - 在设计视图中，添加一个`PictureBox`控件，用于显示摄像头捕获的视频流。 - 可以考虑添加其他控件，如`Button`来启动和停止视频捕获。 3. **初始化摄像头** - 使用`VideoCaptureDevice`类来表示摄像头。在`Form_Load`事件处理程序中，列举可用的摄像头设备，并允许用户选择一个。 ```csharp private VideoCaptureDevice videoSource; private List<VideoCaptureDevice> cameras; private void Form_Load(object sender, EventArgs e) { cameras = new FilterInfoCollection(FilterCategory.VideoInputDevice).ToList(); if (cameras.Count > 0) { // 显示摄像头列表让用户选择 // ... // 初始化第一个摄像头 videoSource = new VideoCaptureDevice(cameras[0].MonikerString); } } ``` 4. **配置摄像头参数** - 设置视频源的帧率、分辨率等参数。例如，可以使用`VideoSource.VideoResolution`属性。 ```csharp videoSource.VideoResolution = videoSource.VideoCapabilities[0]; ``` 5. **处理视频流** - 添加`videoSource_NewFrame`事件处理程序，当摄像头捕获到新帧时，将帧数据转换为`Bitmap`并显示在`PictureBox`中。 ```csharp private void videoSource_NewFrame(object sender, NewFrameEventArgs eventArgs) { Bitmap bitmap = (Bitmap)eventArgs.Frame.Clone(); pictureBox.Image = bitmap; } // 注册事件处理器 videoSource.NewFrame += videoSource_NewFrame; ``` 6. **启动和停止视频捕获** - 在按钮的点击事件中，使用`Start()`和`Stop()`方法控制摄像头的开启和关闭。 ```csharp private void btnStart_Click(object sender, EventArgs e) { if (videoSource != null && !videoSource.IsRunning) { videoSource.Start(); } } private void btnStop_Click(object sender, EventArgs e) { if (videoSource != null && videoSource.IsRunning) { videoSource.SignalToStop(); videoSource.NewFrame -= videoSource_NewFrame; } } ``` 7. **释放资源** - 记得在适当的时候释放摄像头资源，防止内存泄漏。例如，在`Form_Closing`事件中。 ```csharp private void Form_FormClosing(object sender, FormClosingEventArgs e) { if (videoSource != null && videoSource.IsRunning) { videoSource.SignalToStop(); videoSource.Dispose(); } } ``` 以上就是使用C# WinForms调用电脑摄像头的基本步骤。通过这些知识，你可以创建一个简单的视频预览应用。不过，实际项目可能还需要处理更多细节，比如错误处理、用户交互优化、视频录制等功能。随着对.NET和AForge库的深入理解，你可以构建更复杂的多媒体应用。
