Hi!
What actions do I have to do in order to get my objects marshaled by value?
For the moment we are using Marshal by reference, so all my object derive
from MarshalByRef.

Thanks in advance!

Classes must be serializable to be able to transport them by value.

I have tried to mark them with:
[Serializable]

but when I try to connect to the object I get this exception:
An unhandled exception of type 'System.Runtime.Remoting.RemotingException'
occurred in mscorlib.dll
Additional information: Trying to create a proxy to an unbound type.

If I derive the object from MarshalByRef everything works fine, except that
I get a reference instead of the object :)

Hi,

[Original message clipped]

probably because one of the fields of the classes you declared
[Serializable] is not serializable (because its type is
not declared [Serializable]).

try using this settings in your App.config. you'll get
the exact exception instead the generic
System.Runtime.Remoting.RemotingException:

<configuration>
<system.runtime.remoting>
<customErrors mode="off" />
</system.runtime.remoting>
</configuration>

Well, it is much easier to get an object marshaled by ref
then by value. the reason: marshal by value expects
that the whole object graph of a certain object is serializable,
because the remoting infrastructure has to transfer a copy
of the data over the wire.

bye
Rob

Sorry, I don't get any other message. The object I try to marshal only has a
private int, a private string member and two public properties.

Do you implement the ISerializable interface or do you only mark your class
as [Serializable]? You might want to post your class code here.

Thanks,

Sam

Hi!
Here is class code.
[Serializable]
public class Customer
{
private int id;
private string name;
public int ID
{
get{return this.id;}
set{this.id = value;}
}
public string Name
{
get{return this.name;}
set{this.name = value;}
}
public Customer()
{
this.id = int.MinValue;
this.name = "";
}
}

So as you can see I only mark it as Serializable.
