.net remoting在wpf中的应用

我做一个remotting的通讯测试，让控制台程序和wpf窗体通讯。具体实现的功能如下：

1、wpf获取信息在控制台上显示

2、控制台启动wpf，以及在屏幕前端显示

首先，我们来看项目结构：

共三个项目，它们分工明确，test是控制台和wpf的公共类库，它定义了双方通讯的接口，以及接口的实现：

 using System;
 using System.Collections.Generic;
 using System.Linq;
 using System.Text;

 namespace test
 {
     public interface IOfficeService
     {
         void Insert(string stream);
     }
     [Serializable]
     public class OfficeServiceImplement : MarshalByRefObject, IOfficeService
     {
         public void Insert(string stream)
         {
             Console.WriteLine(stream);
         }
     }

     public interface IWPFService
     {
         IntPtr GetHandle();
     }
     [Serializable]
     public class WPFServiceImplement : MarshalByRefObject, IWPFService
     {
         public static Func<IntPtr> GetWPFHandle { set; get; }
         public IntPtr GetHandle()
         {
             if (GetWPFHandle != null)
             {
                 return GetWPFHandle();
             }
             return IntPtr.Zero;
         }
     }
 }

wfaKnowledgeWarehouse 是个控制台项目，用来接收从wpf传回来的消息，并打印到屏幕上：

 using System;
 using System.Collections.Generic;
 using System.Linq;
 using System.Text;
 using System.IO;
 using System.Runtime.Remoting.Channels.Http;
 using System.Runtime.Remoting;
 using System.Runtime.Remoting.Channels;
 using System.Runtime.Serialization.Formatters;
 using System.Net.Sockets;
 using System.Net;
 using test;
 using System.Diagnostics;
 using System.Threading;

 namespace wfaKnowledgeWarehouse
 {
     class Program
     {
         public const string CHANNEL_NAME = "ConsoleService";
         public const string OBJECT_URI = "ConsoleService.rem";

         /// <summary>
         /// 二进制信道处理
         /// </summary>
         public static SoapServerFormatterSinkProvider Provider = new SoapServerFormatterSinkProvider()
         {
             TypeFilterLevel = TypeFilterLevel.Full
         };

         static void Main(string[] args)
         {

             //定义一组服务
             var channel = new HttpServerChannel(CHANNEL_NAME, , Provider);
             RemotingConfiguration.RegisterWellKnownServiceType(typeof(OfficeServiceImplement), OBJECT_URI, WellKnownObjectMode.Singleton);

             var consoleInfo = Console.ReadKey();

             if (consoleInfo.Key == ConsoleKey.A)
             {
                 //如果按下A，获取wpf窗体句柄

                 var ServiceUrl = "http://" + IPAddress.Loopback.ToString() + ":{0}/WPFService.rem";
                 var WpfService = Activator.GetObject(typeof(IWPFService), string.Format(ServiceUrl, )) as IWPFService;

                 try
                 {
                     //启动客户端
                     ProcessStartInfo info = new ProcessStartInfo();
                     info.FileName = @"D:\mywork\WordAddInTest2010\WpfTest\WpfTest\bin\Debug\WpfTest.exe";
                     info.Arguments = "";
                     info.WindowStyle = ProcessWindowStyle.Minimized;
                     Process pro = Process.Start(info);

                     Thread.Sleep();

                    var window= WpfService.GetHandle();

                    Console.WriteLine(window.ToInt32());

                    if (Win32APIs.IsIconic(window) != IntPtr.Zero)
                    {
                        Win32APIs.ShowWindow(window, Win32APIs.WindowState.SW_SHOWNOACTIVATE);
                    }

                    Win32APIs.SetForegroundWindow(window);

                 }
                 catch (Exception ex)
                 {
                     Console.WriteLine(ex);
                 }
             }
             Console.Read();
         }
     }
 }

WpfTest 是wpf项目：

 using System;
 using System.Collections.Generic;
 using System.Linq;
 using System.Text;
 using System.Windows;
 using System.Windows.Controls;
 using System.Windows.Data;
 using System.Windows.Documents;
 using System.Windows.Input;
 using System.Windows.Media;
 using System.Windows.Media.Imaging;
 using System.Windows.Navigation;
 using System.Windows.Shapes;
 using System.Net;
 using test;
 using System.Windows.Interop;
 using System.Runtime.Remoting.Channels;
 using System.Runtime.Remoting.Channels.Http;
 using System.Runtime.Remoting;
 using System.Runtime.Serialization.Formatters;
 using System.Threading;
 using System.Windows.Threading;

 namespace WpfTest
 {
     /// <summary>
     /// MainWindow.xaml 的交互逻辑
     /// </summary>
     public partial class MainWindow : Window
     {
         public const string CHANNEL_NAME = "WPFService";
         public const string OBJECT_URI = "WPFService.rem";

         /// <summary>
         /// 二进制信道处理
         /// </summary>
         public static SoapServerFormatterSinkProvider Provider = new SoapServerFormatterSinkProvider()
         {
             TypeFilterLevel = TypeFilterLevel.Full
         };

         public MainWindow()
         {
             InitializeComponent();
         }

         public static IntPtr WindowPtr { set; get; }

         private void Button_Click(object sender, RoutedEventArgs e)
         {
             var ServiceUrl = "http://" + IPAddress.Loopback.ToString() + ":{0}/ConsoleService.rem";
             var WordService = Activator.GetObject(typeof(IOfficeService), string.Format(ServiceUrl, )) as IOfficeService;

             try
             {
                 WordService.Insert("wbq");
             }
             catch (Exception ex)
             {
                 MessageBox.Show(ex.Message);
             }
         }

         public IntPtr GetHandle()
         {
             return WindowPtr;
         }

         private void Window_Loaded(object sender, RoutedEventArgs e)
         {
             WindowPtr = new WindowInteropHelper(this).Handle;
             var channel = new HttpServerChannel(CHANNEL_NAME, , Provider);
             RemotingConfiguration.RegisterWellKnownServiceType(typeof(WPFServiceImplement), OBJECT_URI, WellKnownObjectMode.Singleton);
             WPFServiceImplement.GetWPFHandle = GetHandle;
         }
     }
 }

wpf项目定义了提供了WPFService服务，同时它又使用控制台提供的ConsoleService服务。

小结：想想，我们程序员为老板，为公司提供了一定的技术服务，同时得到一些报酬；老板和公司得到一些技术服务的同时，给程序员付一定的报酬。要和这个社会打交道，大抵如此吧。
