C# WPF项目实战(经典)

目的：输出两台摄像头图像和两路设备图像，每一路设备截图6张

主要知识：

1. 通过SDK调取摄像头图像，并对图像进行剪裁；

2. WPF中定时器DispatcherTimer用法；

3. WPF中跨线程访问控件方法

Dispatcher.Invoke((Action)delegate {}）；

区别于winform中

this.Invoke((Action)delegate {}）；

4.xml操作：

 XmlDocument xmlDoc = new XmlDocument();xmlDoc.Load(AppDomain.CurrentDomain.BaseDirectory + "\\config.xml");XmlNode settingNode = xmlDoc.DocumentElement;XmlElement e = settingNode.SelectSingleNode("DeviceType") as XmlElement;if (e == null){deviceType = "tps2000";}else{deviceType = e.InnerText;}

5. 带多个参数的委托

            DP1 = new DataProcess(DeviceIP1, LocalPort1,0);DP1.ShowEvent1 = DrawControls1;DP1.Start();//启动线程

6.多线程操作

            Thread t1 = new Thread(new ThreadStart(DataRevThread));                  //开启DataRevThreadt1.Name = "DataRevThread";                                            //线程名字t1.Start();t1.IsBackground = true;                                                  //后台运行

7. UDP接收，解码；

8. emgucv使用；

9. 工厂模式：

ModelFactory MF = new ModelFactory();DM = MF.CreateDataModelFactory_v1(sNeed.ToString());

10.信号量线程间同步

Semaphore TaskSemaphoreData = new Semaphore(0, 2560);           //数据缓存队列缓存区TaskSemaphoreRev.WaitOne();                //等待接收队列

11.Bitmap转换为ImageSource

 [System.Runtime.InteropServices.DllImport("gdi32.dll")]public static extern bool DeleteObject(IntPtr hObject);public static ImageSource ChangeBitmapToImageSource(Bitmap bitmap){IntPtr hBitmap = bitmap.GetHbitmap();ImageSource wpfBitmap = System.Windows.Interop.Imaging.CreateBitmapSourceFromHBitmap(hBitmap,IntPtr.Zero,Int32Rect.Empty,BitmapSizeOptions.FromEmptyOptions());if (!DeleteObject(hBitmap)){throw new System.ComponentModel.Win32Exception();}return wpfBitmap;}

12.Queue和list的操作

包括但是不限于以上内容

代码如下：
