Hi,

I'm extending a serializable class I made. The new class adds some features
that cannot be serialized automatically, this means that I have to implement
the ISerializable interface for my new class. What happens is that I do
serialize what I have written within the GetObjectData method, but now I do
not get to automatically serialize the data from my parent class.
Is there a way to serialize automatically the properties from my parent
class and then to serialize manually only what I have added in the derived
class?

Here's a sample of the code:

[Serializable]

public class OperDataSocketIn : Operator, ISerializable

{

    [NonSerialized]

    private DataSocket dataSocketIn;

    ...

    private OperDataSocketIn( SerializationInfo info, StreamingContext
context)

    {

        dataSocketIn =new DataSocket();

        dataSocketIn.Url= info.GetString("Url");

    }

    void ISerializable.GetObjectData(SerializationInfo info,
StreamingContext context)

    {

        info.AddValue("Url", dataSocketIn.Url);

    }

    ...

}

Using this code after deserializing I get an object that has empty values
except for dataSocketIn.Url.

Thanks, Mark Saccomandi
