C#调用摄像头实现拍照和录像

封装了一个DLL，源码在项目工程里，调用非常简单方便 msxt = new mSheXiangTou(pictureBox1); List temp = null; if ((temp = msxt.GetVideoDevicesNameList) != null) { foreach (string str in temp) { comboBox1.Items.Add(str); } comboBox1.SelectedIndex = 0; } Open.Click += new EventHandler(Open_Click); Close.Click += new EventHandler(msxt.Close_Click); LuXiang.Click += new EventHandler(msxt.LuXiang_Click); Stop.Click += new EventHandler(msxt.TingZhi_Click); PaiZhao.Click += new EventHandler(msxt.PaiZhao_Click); FormClosing += new FormClosingEventHandler(msxt.Form_FormClosing);
