Assemblies / Serialization

Question

Hello.. I am trying to solve a problem but I'm not really sure what to call what I am want do as I am fairly new to C# .net. I have a Windows Service which basically controls threading and nothing else. This service calls another .dll (Base Class) which I have added as a reference to the Windows Service. Now this Base Class will call other .dlls or assemblies on the fly (for example I am pulling the name of the .dll out of a table in the database). I want to be able to carry all the properties and values from the Base Class to the new .dll called. I believe serialization is what I am looking for but every example I've found works just with one solution with mulitple classes not multiple solutions (.dll's). Make sense? thanks for your help.

You shouldn't use serialisation in your case because you deal with separate solutions that means separate application domains. use the MarshalByref class to comunicate between objects in a sparate domains. suppose that you have application client that consumes an object myclass located in other application first make use of the System.Net; and System.Remoting name spaces then derive your object from MarshalByRefObject like this // This is a type that will be // marshaled by reference (MBR) if accessed remotely. public class myclass: MarshalByRefObject { public myclass() { } // This method takes an input string from the caller. public void DisplayMessage(string message) { Console.WriteLine(Message is: {0} message);} // This method returns a value to the caller. public string ReturnMessage() { return Hello from the server!; } } } inorder to transfert this object you have to build a third parti witch is in fact the server that communicates the object to the client using System; using System.Runtime.Remoting; using System.Runtime.Remoting.Channels; using System.Runtime.Remoting.Channels.Http; but don't forget to make of the assembly that holds my class in the server one I mean in addition to those above namesapce you have to in clude using namespace that contains of myclass using System; using System.Runtime.Remoting; using System.Runtime.Remoting.Channels; using System.Runtime.Remoting.Channels.Http; using ........; /*Assembly of my class*/ ; add this code to the server main method // Register a new HttpChannel HttpChannel c = new HttpChannel(14000);// you can use ports of your choice but they must not be used by other programs like 80 for http or 25 smtp ChannelServices.RegisterChannel(c); // Here singleton activation is used. RemotingConfiguration.RegisterWellKnownServiceType( typeof(SimpleRemotingAsm.RemoteMessageObject) RemoteMsgObj.soap WellKnownObjectMode.Singleton); Console.ReadLine(); in your application that consumes that data use this code to consume myclass object data using System; using System.Runtime.Remoting; using System.Runtime.Remoting.Channels; using System.Runtime.Remoting.Channels.Http; using ........; /*Assembly of my class*/ Console.WriteLine(***** SimpleRemoteObjectClient started! *****); Console.WriteLine(Hit enter to end.); // Create a new HttpChannel. HttpChannel c = new HttpChannel(); ChannelServices.RegisterChannel(c); // Get a proxy to remote WKO type. object rmtObj = Activator.GetObject( typeof(SimpleRemotingAsm.myclass) http://localhost:14000/myclass.soap); // Now use the remote object. myclass data = (myclass)rmtObj; simple.DisplayMessage(Hello from the client!); Console.WriteLine(Server says: {0} data.ReturnMessage()); Console.ReadLine();
