How to pass C# method as a callback to CLI/C++ function? -

i have such method in c++/cli:

void foo(onengineclosecallback callback);

with such callback definition:

typedef void (*onengineclosecallback)( int, string ^ errormessage);

the c++/cli compiles. c# code looks this:

static void oncallback( int code, string errormessage) { system.diagnostics.debug.writeline(errormessage); }

and call:

foo(oncallback); // error

"foo not supported language" (error: cs0570).

so how can pass callback cli/c++?

if neither of going post reply i'll because don't answered questions without answers...
