C# WPF项目实战(经典)

wpf经典编程实例

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：

  1. XmlDocument xmlDoc = new XmlDocument();
  2.                 xmlDoc.Load(AppDomain.CurrentDomain.BaseDirectory + "\\config.xml");
  3.                 XmlNode settingNode = xmlDoc.DocumentElement;
  4.  
  5.  
  6.                 XmlElement e = settingNode.SelectSingleNode("DeviceType") as XmlElement;
  7.                 if (e == null)
  8.                 {
  9.                     deviceType = "tps2000";
  10.                 }
  11.                 else
  12.                 {
  13.                   deviceType = e.InnerText;
  14.                 }

5. 带多个参数的委托

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

6.多线程操作

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

7. UDP接收，解码；

8. emgucv使用；

9. 工厂模式：

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

10.信号量线程间同步

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

11.Bitmap转换为ImageSource

  1. [System.Runtime.InteropServices.DllImport("gdi32.dll")]
  2.         public static extern bool DeleteObject(IntPtr hObject);
  3.  
  4.  
  5.         public static ImageSource ChangeBitmapToImageSource(Bitmap bitmap)
  6.         {
  7.             IntPtr hBitmap = bitmap.GetHbitmap();
  8.             ImageSource wpfBitmap = System.Windows.Interop.Imaging.CreateBitmapSourceFromHBitmap(
  9.                 hBitmap,
  10.                 IntPtr.Zero,
  11.                 Int32Rect.Empty,
  12.                 BitmapSizeOptions.FromEmptyOptions());
  13.  
  14.  
  15.             if (!DeleteObject(hBitmap))
  16.             {
  17.                 throw new System.ComponentModel.Win32Exception();
  18.             }
  19.             return wpfBitmap;
  20.         }

12.Queue和list的操作

包括但是不限于以上内容

代码如下：
