.net 2.0

In a form class module (Formtest) this is what I am doing in .NET 2.0:
AppBar.CCInfo.CanApprove

In AppBa there is a struct

the compiler is giving an error as follows:
Accessing a member on 'ChngCtrlUI.frmAppBar.CCInfo' may cause a runtime exception because it is a field of a marshal-by-reference class

Thanks
