Is it possible to get parameters' values for each frame in call stack in .NET

Question

I\'m talking about managed .NET code. If we run any program and attach VS to it we can see parameters\' values for each method in call stack. I\'d like to create a logging s

Answer 1

Parameters values aren't stored in StackFrame instance. In fact, they aren't recorded/logged at all, unless you choose to do it explicitly.

One obvious way to log theses values is to use AOP. It would certainly imply a cost, but in conjunction with a logging framework and the right log level, it may be an alternative. You could also choose to instrument only some types/methods in your basecode, where exceptions are more likely to be thrown. I would probably choose Postsharp for its static weaving capabilities, to emit log calls.

Anyway, it's far from being an ideal solution, but I'm afraid you won't have many options if you're stuck in the managed world.

Answer 2

Your best option is probably to insert the required trace code in the relevant methods. That way you can attach trace listeners and dump values when needed.

I know it is not what you're asking for, but it is one way to get the data.

Alternatively, you can debug the application using WinDbg. The !clstack/!dso commands will let you inspect parameters and stack objects.
