#define help..

[Guest]

Can someone please help with converting this c++ to c#. I couldn't find the
macro of CTL_CODE in c#.

#define CF9_PACKET CTL_CODE(FILE_DEVICE_CF9, CF9_IOCTL_INDEX +21,
METHOD_BUFFERED, FILE_ANY_ACCESS)

Thanks in advance,

No, there is no macro in C# , at least now.

The other poster is correct, Macros as they existed in
c/c++ do not exist in c#, that does not mean you cannot
call the code you want to... take a look at
