C# Remoting

Remoting可建立的Channel有(1)TCP Channel. (2)Http Channel. (3)IPC Channel

.Net 1.1 : TCP Channel、Http Channel.
.Net 2.0 : 之後多了IPC Channel 使用Windows程式間通信系統(IPC:Inter process Communication)

Remoting 的使用流程
1.建立Remoting 物件
2.在Server建立使用Remoting物件的Channel
3.在Client使用Remoting

//------------------ Example --------------------//
1.建立Remoting物件

1.1 建立Interface

1.2.實作Remoting物件

using System; using System.Collections; namespace G5.RemotingEvent.ICommon { public delegate void PAEventHandler(Hashtable fax); public interface IG5Business { void SendPA(Hashtable fax); } }

using System; using System.Collections; using G5.RemotingEvent.ICommon; namespace G5.RemotingEvent.RemoteObj { public class G5Business:MarshalByRefObject,IG5Business { // 建立Event public static event PAEventHandler PASendedEvent; #region public void SendPA(Hashtable fax) { if (PASendedEvent != null) { PASendedEvent(fax); } } #endregion public override object InitializeLifetimeService() { return null; } } }

2.在Server建立使用Remoting物件的Channel

2.1 using //using System.Runtime.Remoting.Channels.Http; //using System.Runtime.Remoting.Channels.Tcp; using System.Runtime.Remoting.Channels.Ipc; 2.2 建立Channel // IPC Channel IpcChannel channel = new IpcChannel("G5Channel"); ChannelServices.RegisterChannel(channel); RemotingConfiguration.RegisterWellKnownServiceType(typeof (G5Business), "G5Loader", WellKnownObjectMode.Singleton); //TCP Channel //TcpServerChannel channel = new TcpServerChannel(3210); //ChannelServices.RegisterChannel(channel, false); //RemotingConfiguration.RegisterWellKnownServiceType(typeof(G5Business), "G5Loader", WellKnownObjectMode.Singleton); // Http Channel // HttpChannel channel = new HttpChannel(8080); // ChannelServices.RegisterChannel(channel); // RemotingConfiguration.RegisterWellKnownServiceType(typeof(G5Business),"G5Business.soap",WellKnownObjectMode.Singleton); G5Business.PASendedEvent += new PAEventHandler(OnPASended);

3.在Client使用Remoting

1.using //using System.Runtime.Remoting.Channels.Http; //using System.Runtime.Remoting.Channels.Tcp; using System.Runtime.Remoting.Channels.Ipc; 2.使用Channel private IG5Business faxBus = null; // IPC Channel string stringIpc = "ipc://G5Channel/G5Loader"; faxBus = (IG5Business)Activator.GetObject(typeof(IG5Business), stringIpc); //TCP Channel //string stringTcp = "tcp://localhost:3210/TestLoader"; //faxBus = (IG5Business)Activator.GetObject(typeof(IG5Business), stringTcp); //Http Channel //HttpChannel channel = new HttpChannel(0); //ChannelServices.RegisterChannel(channel); //faxBus = (IG5Business)Activator.GetObject(typeof(IG5Business), // http://localhost:8080/G5Business.soap);
