[Mono-list] Can someone analyze this code and tell me what happens

[Steve Lessard]

My initial guess without the info requested by Alex is that the exception thrown has something to do with not being able to serialize your dataStruct instance. In that case the likely cause of the problem is that the dataStruct class is not decorated with the [Serializable] attribute.
