Remoting在客户端服务器怎么实现?
一道面试题原题!
------解决方案--------------------
第一步:建议server端程序:
1 项目—新建—控制台程序--
using System;
using System.Runtime.Remoting;
using System.Runtime.Remoting.Channels;
using System.Runtime.Remoting.Channels.Tcp;
using System.Security.Permissions;
public class Server
{
[SecurityPermission(SecurityAction.Demand)]
public static void Main(string[] args)
{
TcpChannel serverChannel = new TcpChannel(8081);// 8081为为端口号
ChannelServices.RegisterChannel(serverChannel, true);//注册通道
//注册远程对象
RemotingConfiguration.RegisterWellKnownServiceType(typeof(RemoteTest), "proname", WellKnownObjectMode.Singleton);
Console.WriteLine("Press any KEY to exit the server and stop the channel.");
Console.ReadLine();
serverChannel.StopListening(null); //停止监听
ChannelServices.UnregisterChannel(serverChannel); //注销通道
}
}
第二步:建议client端程序:
项目—新建—控制台程序---
using System;
using System.Runtime.Remoting;
using System.Runtime.Remoting.Channels;
using System.Runtime.Remoting.Channels.Tcp;
using System.Security.Permissions;
public class Client
{
[SecurityPermission(SecurityAction.Demand)]
public static void Main(string[] args)
{
TcpChannel clientChannel = new TcpChannel(); //创建通道
ChannelServices.RegisterChannel(clientChannel,true);//注册通道
//获取远程对象
//(1) WellKnown激活模式调用RemotingConfiguration的静态方法RegisterActivatedClientType()。
/*WellKnownClientTypeEntry remoteType = new WellKnownClientTypeEntry(typeof(RemoteTest), "tcp://192.168.168.165:9090/RemoteObject.rem");
RemotingConfiguration.RegisterWellKnownClientType(RemoteTest);
RemoteTest obj2 = new RemoteTest(); */
//客户端激活模式()调用Activator进程的GetObject()方法
RemoteTest obj2 = (RemoteTest)Activator.GetObject(typeof(RemoteTest), "tcp://192.168.168.165:8081/ proname ");
person m = new person("TempUser", "men", "19");
m = obj2.getInfo(m);
Console.WriteLine(m.name);
Console.Read();
}
}
注意看上面代码,两段程序代码里面反复出现RemoteTest,person等字眼,一看就知道这两个是大家自己定义的类,马上我们建立它,“tcp://192.168.168.165:8081/proname”,其中,tcp代表的tcp协议,如果是http当然就应该上http协议了,后面是IP地址和端口号,即服务器端的地址和端口号,后面的proname叫做远程对象服务名,我们暂且不记它,只要保持一致就可以了,其实在程序中对应ApplicationName属性的内容。
回到主题上来,刚才的RemoteTest,person等类都没有,直接编译肯定出错,怎么办,马上解决。
第二步:建议远程服务对象:
项目—新建—控制台程序
注意,这次建立的不需要运行,直接编译成dll文件即可,然后在服务器端和客户端分别添加引用即可,代码如下:
using System;
using System.Runtime.Remoting;
// Remote object.
public class RemoteTest : MarshalByRefObject
{
private int clientCount = 0;
public int ReCount(int i)
{
clientCount = (clientCount++)+i;
return (clientCount);
}
public string HelloWorld(string name)
{
Console.WriteLine("GOOD MORNING!");
return "Hi," + name;
}
public person getInfo(person m)
{
Console.WriteLine("THERE HAVE ONE PERSON INFOMATION HAS RESIVED!");
Console.WriteLine(m.name+"-"+m.age+"-"+
