C#构建一个简单的分布式应用程序(.net远程处理)-优快云博客

本文介绍了一个简单的.NET远程对象交互示例，包括三个程序集：SimpleRemotingAsm.dll、SimpleRemoteObjectServer.exe 和 SimpleRemoteObjectClient.exe。示例通过 HttpChannel 实现了客户端和服务端之间的远程对象调用。

摘要生成于 C知道，由 DeepSeek-R1 满血版支持，前往体验 >

由3个.NET程序集构成：

SimpleRemotingAsm.dll

SimpleRemoteObjectServer.exe

SimpleRemoteObjectClient.exe

下面是代码

SimpleRemotingAsm控制台程序

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

namespace SimpleRemotingAsm
{

//这个类型在被远程访问时会以引用方式封送(MBR)
public class RemoteMessageObject : MarshalByRefObject
{
public RemoteMessageObject()
{
Console.WriteLine("Constructing RemoteMessageObject!");

}
//这个方法从调用那里获取一个输入字符串
public void DisplayMessage(string msg)
{
Console.WriteLine("Message is:{0}", msg);
}
//这个方法把值返回调用方
public string ReturnMessage()
{
return "Hello from the server";
}
}

}

SimpleRemoteObjectServer控制台程序

using System;
using System.Collections.Generic;
using System.Text;
using System.Runtime.Remoting.Channels;
using System.Runtime.Remoting.Channels.Http;
using System.Runtime.Remoting;

namespace SimpleRemoteObjectServer
{
class Program
{
static void Main(string[] args)
{
Console.WriteLine("*****SimpleRemoteObjectServer started!******");
Console.WriteLine("Hit enter to end");

//注册一个新的信道
HttpChannel c = new HttpChannel(32469);
ChannelServices.RegisterChannel(c, false);

//注册一个WKO类型，使用单例激活

RemotingConfiguration.RegisterWellKnownServiceType(typeof(SimpleRemotingAsm.RemoteMessageObject), "RemoteMsgObj.soap", WellKnownObjectMode.Singleton);
Console.ReadLine();
}
}
}

SimpleRemoteObjectClient控制台程序

using System;
using System.Collections.Generic;
using System.Text;
using System.Runtime;
using System.Runtime.Remoting.Channels;
using System.Runtime.Remoting.Channels.Http;
using System.Runtime.Remoting;
using SimpleRemotingAsm;

namespace SimpleRemoteObjectClient
{
class Program
{
static void Main(string[] args)
{
Console.WriteLine("*****SimpleRemoteObjectClient started!******");
Console.WriteLine("Hit enter to end");
//注册一个新的信道
HttpChannel c = new HttpChannel();
ChannelServices.RegisterChannel(c,false);

//注册一个WKO类型
object remoteObj = Activator.GetObject(typeof(SimpleRemotingAsm.RemoteMessageObject),"http://localhost:4313/RemoteMsgObj.soap");
//现在使用远程对象
RemoteMessageObject simple = (RemoteMessageObject)remoteObj;
simple.DisplayMessage("Hello from the client");
Console.WriteLine("Server says:{0}",simple.ReturnMessage());
Console.ReadLine();

}
}
}
