Remoting事件序列一：客户端触发服务器端事件

最近常有网友问我关于Remoting事件的问题，我也正好有些时间，于是决定写两篇关于Remoting事件的入门随笔，希望对新手有所帮助．．谢谢

随笔一：客户端触发服务器端事件

通讯类：

using System;
using System.Collections; 
using System.Runtime.Remoting;
using System.Runtime.Remoting.Channels;
using System.Runtime.Remoting.Channels.Tcp;
using System.Runtime.Remoting.Channels.Http;

using System.Runtime.Serialization.Formatters; 

namespace RemotingSamples 
{

    public class Server
    {
        public static void Main(string [] args) 
        {

            BinaryServerFormatterSinkProvider serverProvider = new BinaryServerFormatterSinkProvider();
            BinaryClientFormatterSinkProvider clientProvider = new BinaryClientFormatterSinkProvider();
            serverProvider.TypeFilterLevel = TypeFilterLevel.Full;  

            IDictionary props=new Hashtable(); 
            props["port"]=8085;  

            TcpChannel chan1 = new TcpChannel(props,clientProvider,serverProvider);


            ChannelServices.RegisterChannel(chan1);



            RemotingConfiguration.RegisterWellKnownServiceType
                (
                typeof(HelloServer),
                "SayHello",
                WellKnownObjectMode.Singleton
                );


            

            System.Console.WriteLine("Press Enter key to exit");
            System.Console.ReadLine();

        }

    }
}

服务器端代码：

using System;
using System.Collections; 
using System.Runtime.Remoting;
using System.Runtime.Remoting.Channels;
using System.Runtime.Remoting.Channels.Tcp;
using System.Runtime.Remoting.Channels.Http;

using System.Runtime.Serialization.Formatters; 

namespace RemotingSamples 
{

    public class Server
    {
        public static void Main(string [] args) 
        {

            BinaryServerFormatterSinkProvider serverProvider = new BinaryServerFormatterSinkProvider();
            BinaryClientFormatterSinkProvider clientProvider = new BinaryClientFormatterSinkProvider();
            serverProvider.TypeFilterLevel = TypeFilterLevel.Full;  

            IDictionary props=new Hashtable(); 
            props["port"]=8085;  

            TcpChannel chan1 = new TcpChannel(props,clientProvider,serverProvider);


            ChannelServices.RegisterChannel(chan1);



            RemotingConfiguration.RegisterWellKnownServiceType
                (
                typeof(HelloServer),
                "SayHello",
                WellKnownObjectMode.Singleton
                );


            

            System.Console.WriteLine("Press Enter key to exit");
            System.Console.ReadLine();

        }

    }
}

客户端代码：

using System;
using System.Collections; 
using System.Runtime.Remoting;
using System.Runtime.Remoting.Channels;
using System.Runtime.Remoting.Channels.Tcp;
using System.Runtime.Remoting.Channels.Http;
using System.IO;
using System.Runtime.Serialization.Formatters; 

namespace RemotingSamples 
{
    public class Client
    {
        public static void Main(string[] args)
        {

            BinaryServerFormatterSinkProvider serverProvider = new BinaryServerFormatterSinkProvider();
            BinaryClientFormatterSinkProvider clientProvider = new BinaryClientFormatterSinkProvider();
            serverProvider.TypeFilterLevel = TypeFilterLevel.Full;  
            //使用TCP通道得到远程对象
            IDictionary props = new Hashtable();
            props["port"] = 0;
            TcpChannel chan1 = new TcpChannel(props, clientProvider, serverProvider);
            ChannelServices.RegisterChannel(chan1);
            HelloServer obj1 = (HelloServer)Activator.GetObject(
                typeof(RemotingSamples.HelloServer),
                "tcp://localhost:8085/SayHello");
            if (obj1 == null)
            {
                System.Console.WriteLine(
                    "Could not locate TCP server");
            }


            obj1.myevent += new MyEventHandler(obj1.eventmethod);


            Console.WriteLine(
                "Client1 TCP HelloMethod {0}",
                obj1.HelloMethod("Caveman1"));

            Console.ReadLine();
        }
    }
}

代码很简单，我就不做描述了，有问题直接留言，我会尽快做出回复．．
