Subject: Call to base constructor
Print | Individual message | Show original | Report this message | Find messages by this author
Hi!

I have this case where I need to inject code in a constructor AFTER
the call to the base constructor.

This is modifying an existing type so I do not have control over
calling the base constructor.

Is there any way I can search through the instructions and detect the
call to the base constructor.

   L_0000: ldarg.0
   L_0001: call instance void [mscorlib]System.Object::.ctor()
 -> Inject code here ........

Is there any generic way I can solve this so I can make sure my code
is injected after the call to the base constructor?

Regards

Bernhard Richter

That should be pretty simple. When you're modifying a constructor method,
just look for the first instruction after which the evaluation stack is
empty. That should be the constructor delegation call.

(Disclaimer: I'm not way an IL expert, so I'm not 100% sure about this, but
I'd try it this way.)

Except when creating structs with a non default ctor ;)
