在WCF服务中使用表单控件 [英] Use Form Controls Into WCF Service

问题描述

我编写了一个程序，该程序具有两个控制台应用程序(组件A和B)和一个WCF服务库.
我将A和B连接在一起，因此消息可以从A传输到B或从B传输到A(WCF双工).
为此，我将WCF服务库的引用添加到A& B项目.
现在，我想将这些控制台应用程序更改为WinForm应用程序，但是我不能这样做
因为在控制台应用程序中，我们有console.writeline()，它可以在WCF服务库中使用，但是在WinForm中，MessageBox不能在WCF服务中使用.
我也无法添加A&的引用B到Wcf服务，因为它产生循环依赖性错误

这是带有控制台应用程序的项目:

在Project A Program.cs文件中:

I Wrote a program that has two Console application(assusme A & B) and a WCF Service Library.
I connected A and B together so message can be transfer from A to B or B to A(WCF Duplex).
To Do this i added the reference of WCF Service Library to both A & B project.
Now I Want To Change these Console Applications To WinForm application but i cannot do that
because in console application we have console.writeline() that it Can be use in WCF Service Library But In WinForm,MessageBox Cannot be use in WCF Service.

Also I Cannot Add Reference Of A & B to Wcf Service Because it makes Circular Dependency Error

This Is The Project With Console Applications :

In Project A Program.cs file :

 internal static void StartService()
{
   myServiceHost = new ServiceHost(typeof(WCF.MessageService));

   myServiceHost.Open();
}

internal static void StopService()
{
   if (myServiceHost.State != CommunicationState.Closed)
      myServiceHost.Close();
}

static void Main()
{
   StartService();
   Console.WriteLine("Service running; press return to exit");
   Console.ReadLine();
   StopService();
   Console.WriteLine("stopped");
}

在Project B Program.cs文件中:

In Project B Program.cs file:

    class ClientCallback : IMyMessageCallback
 {
   public void OnCallback(string message)
   {
      Console.WriteLine("message from the server: {0}", message);
   }
 }

 class Program
 {
   static void Main()
   {
      Console.WriteLine("Client - wait for service");
      Console.ReadLine();

      WSDualHttpBinding binding = new WSDualHttpBinding();
      EndpointAddress address =
            newEndpointAddress("http://localhost:8731/Design_Time_Addresses/MessageService/Service1/");

      ClientCallback clientCallback = new ClientCallback();
       InstanceContext context = new InstanceContext(clientCallback);

      DuplexChannelFactory<IMyMessage> factory =
         new DuplexChannelFactory<IMyMessage>(context, binding, address);

      IMyMessage messageChannel = factory.CreateChannel();

      messageChannel.MessageToServer("From the client");

      Console.WriteLine("Client - press return to exit");
      Console.ReadLine();

   }
}

在IMYMessage.cs文件(WCF服务库)中:

In IMYMessage.cs File (WCF Service Library):

   public interface IMyMessageCallback
{
  [OperationContract(IsOneWay = true)]
  void OnCallback(string message);
}

[ServiceContract(CallbackContract = typeof(IMyMessageCallback))]
public interface IMyMessage
{
  [OperationContract]
  void MessageToServer(string message);
}

在MessageService.cs文件(WCF服务库)中:

In MessageService.cs File(WCF Service Library) :

 public class MessageService : IMyMessage
{
  public void MessageToServer(string message)
  {
     Console.WriteLine("message from the client: {0}", message);
     IMyMessageCallback callback =
           OperationContext.Current.
                 GetCallbackChannel<IMyMessageCallback>();

     callback.OnCallback("message from the server");

     new Thread(ThreadCallback).Start(callback);
   }

   private void ThreadCallback(object callback)
   {
     IMyMessageCallback messageCallback = callback as IMyMessageCallback;
     for (int i = 0; i < 10; i++)
     {
        messageCallback.OnCallback("message " + i.ToString());
        Thread.Sleep(1000);
     }
  }
}

为什么不将基于控制台的日志记录替换为 Log4Net [^ ]

Why not replace your console based logging with Log4Net[^]
