.Net Remoting Walkthrough

Remoting is the process of two pieces of software communicating across application domains.
Start a Class Library call it say ShalvinObject. Create a class that inherits from MarshalByRefObject.

namespace ShalvinObject
{
class RemoteObject : MarshalByRefObject
{
public int Mul(int i, int j)
{
return i * j;
}
}

Now we are going to host the service. This can be done with Console, Windows Forms or Web Service.
Letsuse Windows Forms.
Add to a reference to the previously created dll, ie. ShalvinObject.dll and System.Runtime.Remoting.


using System.Runtime.Remoting;
using System.Runtime.Remoting.Channels;
using System.Runtime.Remoting.Channels.Tcp;

private void Form1_Load(object sender, EventArgs e)
{
TcpChannel c = new TcpChannel(900);
ChannelServices.RegisterChannel(c);
RemotingConfiguration.RegisterWellKnownServiceType(typeof(ShalvinObject.RemoteObject), "Shalvin", WellKnownObjectMode.Singleton);
}

Now for testing the service lets create another Windows Application. Here too set references to ShalvinObject.dll and System.Runtime.Remoting.


using ShalvinObject;
using System.Runtime.Remoting;
using System.Runtime.Remoting.Channels;
using System.Runtime.Remoting.Channels.Tcp;


private void Form1_Load(object sender, EventArgs e)
{
TcpChannel c = new TcpChannel();
ChannelServices.RegisterChannel(c);
object obj = Activator.GetObject(typeof(ShalvinObject.RemoteObject), "tcp://localhost:900/Shalvin");
RemoteObject ro = (RemoteObject)obj;
int intRes = ro.Mul(56, 45);
MessageBox.Show(intRes.ToString());
}
