[Mono-dev] Embedding Mono - NULL return value in C#

[marcus julius]

Hi,

I call a c++ function from C# using mono.
For instance,

[MethodImplAttribute(MethodImplOptions.InternalCall)]
extern internal static Object get_ai_behavior_object(int id);

When the function returns a NULL object, there is a NullReferenceException. I think it occurs because C# tries to cast null to System.Object. 

Is there a way to avoid this without using try-catch which slows the program or a dummy Null object I need to create?

Thanks,

Mesut,
