[Mono-devel-list] Remoting of an ArrayList in Mono .24

[Matt Davey]

Hi,

First off, Mono 0.24 remoting is a massive jump in functionality over
previous version. 0.24 is very cool indeed.

I'm currently trying to get a Windows XP C# console application talking to a
Mono 0.24 server running on RH 8.0 using the new interface support in 0.24.
Eveything works fine apart from when I try to send an ArrayList from the
Windows client to the Mono server.

Client code:

ChannelServices.RegisterChannel(new TcpChannel(0));
IServerObject s =
Activator.GetObject(typeof(IServerObject),"tcp://localhost:8085/Test") as
IServerObject;
ArrayList al = new ArrayList();
al.Add("one");
al.Add("two");
s.Send(al);

server code:

public interface IServerObject
{
void Send(ArrayList al);
}

public class HelloServer: MarshalByRefObject , IServerObject
{

public void Send(ArrayList al)
{
foreach (object o in al)
{
Console.WriteLine(o);
}
}
}

I see no errors on RH, but on the client I get this:

Unhandled Exception: System.Runtime.Remoting.RemotingException: Underlying

If I run the client and server on MS .NET everything works fine.
