本文展示了如何在C#的WinForm环境下使用摄像头进行图像抓取和录制。通过创建`Pick`类调用avicap32.dll库，实现了在Form1加载时启动摄像头，并提供了抓图和停止功能。点击按钮`b_pic`可以进行拍摄，选择路径保存图片，并能在窗体中显示。

using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Text; using System.Windows.Forms; using webcam; using PickHead; namespace test_avicap { public partial class Form1 : Form { // WebCamera wc; Pick pick; public Form1() { InitializeComponent(); } private void Form1_Load(object sender, EventArgs e) { //b_play.Enabled = false; //b_stop.Enabled = true; //panelPreview.Size = new Size(330, 330); //wc = new WebCamera(panelPreview.Handle, panelPreview.Width, panelPreview.Height); //wc.StartWebCam(); int left=0; int top=0; int width=352; int height=288; pick = new Pick( panelPreview.Handle, left,top, width, height ); pick.Start(); } private void b_play_Click(object sender, EventArgs e) { //b_play.Enabled = false; //b_stop.Enabled = true; //panelPreview.Size = new Size(330, 330); //wc = new WebCamera(panelPreview.Handle, panelPreview.Width, panelPreview.Height); //wc.StartWebCam(); int left = 0; int top = 0; int width =352; int height = 288; pick = new Pick(panelPreview.Handle, left, top, width, height); pick.Start(); } private void b_stop_Click(object sender, EventArgs e) { //wc.CloseWebcam(); pick.Stop(); } protect
