学习技术知识一个好的方法是先动手,再深入,
给出一个最简单的Remoting程序示例(C#)如下:
Step1:创建类库(DLL)工程RemotingObjects,类Person代码如下:
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; namespace RemotingObjects { public interface IPerson { String getName(String name); } public class Person : MarshalByRefObject, IPerson { public Person() { Console.WriteLine("[Person]:Remoting Object ‘Person‘ is activated."); } public String getName(String name) { return name; } } }Step2:创建控制台工程RemotingServer(添加项目引用RemotingObjects),类Server代码如下:
using System; using System.Collections.Generic; using System.Linq; using System.Runtime.Remoting; using System.Runtime.Remoting.Channels; using System.Runtime.Remoting.Channels.Tcp; using System.Text; using System.Threading.Tasks; namespace RemotingServer { class Server { static void Main(string[] args) { TcpChannel channel = new TcpChannel(8080); ChannelServices.RegisterChannel(channel, false); RemotingConfiguration.RegisterWellKnownServiceType(typeof(RemotingObjects.Person), "RemotingPersonService", WellKnownObjectMode.SingleCall); System.Console.WriteLine("Server:Press Enter key to exit"); System.Console.ReadLine(); } } }
Step3:创建控制台工程RemotingClient(添加项目引用RemotingObjects及必要类库),类Client代码如下:
(PS:正式应用开发,不需要也不应该直接引用RemotingObjects类库,而应该引用相关Remoting类的接口库。)
using RemotingObjects; using System; using System.Collections.Generic; using System.Linq; using System.Runtime.Remoting.Channels; using System.Runtime.Remoting.Channels.Tcp; using System.Text; using System.Threading.Tasks; namespace RemotingClient { class Client { static void Main(string[] args) { TcpChannel channel = new TcpChannel(); ChannelServices.RegisterChannel(channel, false); IPerson obj = (IPerson)Activator.GetObject(typeof(RemotingObjects.IPerson), "tcp://localhost:8080/RemotingPersonService"); if (obj == null) { Console.WriteLine("Couldn‘t crate Remoting Object ‘Person‘."); } Console.WriteLine("Please enter your name:"); String name = Console.ReadLine(); try { Console.WriteLine(obj.getName(name)); } catch (System.Net.Sockets.SocketException e) { Console.WriteLine(e.ToString()); } Console.ReadLine(); } } }Step4:运行编译出的EXE:RemotingServer.exe和RemotingClient.exe,查看运行结果。
