Title Body

Ok here it goes, i'm using oracle's ContentAccess library in C#, the library is programmed in C. I use some functions of the library to extract text from diffrent files. the c library uses async communication by function pointers (Delegates). i have 1 class and 1 struct that is needed to use the functions, the struct is called BaseIO and contains functions pointers that points to my code in C# to read files. everything is fine, until cli moves my class, and i get an MemoryAccessException. here is the class, struct and function signature: [UnmanagedFunctionPointerAttribute(CallingConvention.Cdecl)] public delegate DAERR CloseDelegate(IntPtr hfile); [UnmanagedFunctionPointerAttribute(CallingConvention.Cdecl)] public delegate DAERR ReadDelegate(IntPtr hfile, IntPtr dataPtr, UInt32 size, IntPtr count); [UnmanagedFunctionPointerAttribute(CallingConvention.Cdecl)] public delegate DAERR WriteDelegate(IntPtr hfile, IntPtr dataPtr, int size, IntPtr count); [UnmanagedFunctionPointerAttribute(CallingConvention.Cdecl)] public delegate DAERR SeekDelegate(IntPtr hfile, int wFrom, int dwOffset); [UnmanagedFunctionPointerAttribute(CallingConvention.Cdecl)] public delegate DAERR TellDelegate(IntPtr hfile, IntPtr dwOffset); [UnmanagedFunctionPointerAttribute(CallingConvention.Cdecl)] public delegate DAERR GetInfoDelegate(IntPtr hfile, UInt32 dwInfoId, IntPtr pInfo); [UnmanagedFunctionPointerAttribute(CallingConvention.Cdecl)] public delegate DAERR Seek64Delegate(IntPtr hfile, ushort wFrom, Int64 dwOffset); [UnmanagedFunctionPointerAttribute(CallingConvention.Cdecl)] public delegate DAERR Tell64Delegate(IntPtr hfile, Int64 dwOffset); struct BaseIO { public CloseDelegate IOCLOSEPROC; public ReadDelegate IOREADPROC; public WriteDelegate IOWRITEPROC; public SeekDelegate IOSEEKPROC; public TellDelegate IOTELLPROC; public GetInfoDelegate IOGETINFOPROC; public IntPtr IOOPENPROC; public Seek64Delegate IOSEEK64PROC; publi
