Order of exception handling stack frames on the call stack

Question

What is the order in which exception handling stack frames are pushed onto the call stack in say C#. If i have a method:

private void MyMethod() {
  try {
    DoSomething();  
  }
  catch (Exception ex)
  {
    //Handle
  }
}

Is a separate stack frame created for each exception handler as follows?

DoSomething stackframe<br/>
Exception stackframe<br/>
MyMethod stackframe<br/>

OR

DoSomething stackframe<br />
MyMethod stackframe<br />
Exception stackframe<br />

OR

something else?

No, adding an exception handler doesn't add a new frame to the call stack. It just adds appropriate information so that when an exception is thrown, at each level of the call stack the framework can find the appropriate handler for that exception (if indeed there is an appropriate handler).

It's a little bit like garbage collection, where at any point of execution the GC can work out which local variables should still count as GC roots - essentially there's more to a method than the executable code itself :)
