Problem Deserialzing

[bigfoot3d]

The problem I am having with Serialization is the Deserialization side I believe.

I get this SerializationException "Unable to find assembly 'HFHRemoteHelpClientApp, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'."

This is where the error occurs:

At the bottom of both the client and the server I have this serializable class.

[SIZE=2][COLOR=#0000ff]End[/COLOR][/SIZE][SIZE=2][COLOR=#0000ff]Class[/COLOR][/SIZE]

Any ideas?

If you define ClassPacket class in two different assemblies then these two classes are two different classes and can't be serialized between. You have to define this class in a Class Library project and compile it to the dll assembly and reference this by both parties that want to serialize this.

Ok, guess I have to do that then. I didn't want to have a DLL with my EXE file when I was done, but guess I don't have a choice. Either that or don't serialize.

Thanks again for the response.

 

[JohnH]

Either that or use the System.Xml.Serialization.XmlSerializer instead of the BinaryFormatter.

Thank You

John, I took your advice and went ahead with the XML Serialization.
