silverlight4提供了摄像头机麦克风访问的API，尝试了一下，还不错。现在将简单的程序记录一下 sl前台呢，有两个控件，一个是用于显示摄像头捕捉到的内容，另一个是个按钮用来启动摄像头。代码 < Rectangle Height ="169" HorizontalAlignment ="left" Margin ="37,21,0,0" Name ="rectangle1" Stroke

sl前台呢，有两个控件，一个是用于显示摄像头捕捉到的内容，另一个是个按钮用来启动摄像头。

代码

< Rectangle Height ="169" HorizontalAlignment ="Left" Margin ="37,21,0" Name ="rectangle1" stroke ="Black" strokeThickness ="1" VerticalAlignment ="Top" Width ="236" />
< Button Content ="Button" Height ="23" HorizontalAlignment ="Left" Margin ="120,196,0" Name ="button1" VerticalAlignment ="Top" Width ="75" Click ="button1_Click" />

后台呢，是给摄像头的内容传递到rectangle的方法。

代码

Capturesource source = new Capturesource();
            if (source != null )
            {
                source.Stop();

                source.VideoCaptureDevice = CaptureDeviceConfiguration.GetDefaultVideoCaptureDevice();
                VideoBrush vidBrush = new VideoBrush();
                vidBrush.Setsource(sourc E);
                this .rectangle1.Fill = vidBrush;
                if (CaptureDeviceConfiguration.AllowedDeviceAccess || CaptureDeviceConfiguration.requestDeviceAccess())
                {
                    source.Start();
                }
            }

使用模拟摄像头做的效果
