Getting token from an address

Question

Hi!

I'm trying to get the symbol information for an address I got from .NET callstack.
I read that symbols can be resolved using ISymUnmanagedReader, but it only get a token as input for its "GetMethod" function.
Can I somehow get the matching token to the address I have so I can use that "GetMethod" function?

Or: is there another way to do this?

thanks :)

Answer 1

ISymUnmanagedReader is for getting data from a symbol store; for that I always interpreted that to mean an assembly (and pdb file if it existed).

How did you get the address that you wish to get the type/method for? Are you using a profiler or a debugger?

Answer 2

I'm using the debugging API.
I'm doing something like:
ICorDebugChain* chain = NULL;
ICorDebugFrame* frame = NULL;
ICorDebugFunction* function = NULL;
ICorDebugCode* code = NULL;

thread->GetActiveChain(&chain);
chain->GetActiveFrame(&frame);
frame->GeFunction(&func);
function->GetCode(&code);
CORDB_ADDRESS address = 0;
code->GetAddress(&address);

I know I can get here the token, But I need to save just my addresses.
And I DO want to get the symbols from the PDB file. Do I need to use the "ISymUnmanagedReader" or there is another way?

Answer 3

You can get the token from the ICorDebugFrame or the ICorDebugFunction. Using ISymUnmanagedReader is fine.
