Answering "Which method called me?" at the run-time in .NET? Or is CallStack data readable by the code?

Question

Presume that there are methodA() , methodB() and methodC().

And methodC() is called at the run-time.

Is is possible to know methodC() is called from what method?

I was thinking if CallStack can be read at the run-time for some checks? If yes, I think it should not be a big deal.

Any ideas?

Thanks!

Answer 1

Use the StackTrace and StackFrame classes. For example:

  StackTrace stackTrace = new StackTrace();          
  StackFrame[] stackFrames = stackTrace.GetFrames();

  foreach (StackFrame stackFrame in stackFrames)
  {
    string method = stackFrame.GetMethod().Name;
    // do some stuff with method
  }

Answer 2

Yes, the call stack can be read at runtime using StackTrace.Get­Frames.
