中间类using System;using System.Collections.Generic;using System.Text;using System.Runtime.InteropServices;using Jeez.Common.Base; namespace RemoteObject{ //客户端获取到服务端的对象实际是一个对象的引用，必须继承：MarshalByRefObject public class DBServer : System.MarshalByRefObject { public DBServer() { } public static string Uid; public static string Pwd; public static string AllData; public string ReData() { return AllData; } public string ReAll() { return Uid + Pwd; } }}说明1:在Remoting中的远程对象中，如果还要调用或传递某个对象，例如类，或者结构，则该类或结构则必须实现串行化Attribute[SerializableAttribute]：说明2:将该远程对象以类库的方式编译成Dll。这个Dll将分别放在服务器端和客户端，以添加引用说明3:在Remoting中能够传递的远程对象可以是各种类型，包括复杂的DataSet对象，只要它能够被序列化服务端using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Text;using System.Windows.Forms;using System.Net.Sockets;using System.Net;using System.Threading;using System.Runtime.Remoting;using System.Runtime.Remoting.Channels;using System.Runtime.Remoting.Channels.Tcp;using RemoteObject; namespace Server{ public partial class RemoteServer : Form { public RemoteServer() { InitializeComponent(); } public string ConSql; public static string DbName; //实例通道，为tcp传输提供端口 TcpServerChannel channel = new TcpServerChannel(85); bool IsRegister = false; private void Register() //注册 { IPHostEntry ipHost = Dns.Resolve(Dns.GetHostName()); IPAddress ipAddr = ipHost.AddressList[0]; //可以给RemoteObject.DBServer类传递数据....... //注册通道 ChannelServices.RegisterChannel(channel,false); IsRegister = true; //注册远程对象,即激活. RemotingConfiguration.RegisterWellKnownServiceType(typeof(RemoteObject.DBServer), "DBServer", WellKnownObjectMode.SingleCall); } private void CancelRegister() //取消注册 { if (IsRegister == true) { ChannelServices.UnregisterChannel(channel); IsRegister = false; } } }} 客户端using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Text;using System.Runtime.Remoting.Channels;using System.Runtime.Remoting.Channels.Tcp;using System.Runtime.Remoting;using RemoteObject; namespace Client{ public partial class RemoteClient : Form { public RemoteClient() { InitializeComponent(); } TcpClientChannel Tcc = new TcpClientChannel(); public bool IsRegister = false; private void Register(string Ip,string Port) //(Ip:服务端Ip Port:服务端端口) { ChannelServices.RegisterChannel(Tcc,false); IsRegister = true; DBServer remoteobj = (DBServer)Activator.GetObject(typeof(DBServer), "tcp://" + Ip + ":" + Port +"/DBServer"); //返回的数据 string Data = remoteobj.ReData(); string UP = remoteobj.ReAll(); } private void OverRegister() //取消注册 { if (IsRegister == true) { ChannelServices.UnregisterChannel(Tcc); IsRegister = false; } } }}
