Hi,
First of all, this line won't work:
String.Format("Unhandled AppDomain exception", args);
You need to have {0} somewhere in your string, which will be replaced by
args.ToString(). That's what String.Format() does. I'm not sure that this
will cause a runtime exception, or will just have your extra parameter
ignored, but still figured you should know.
Now, on to your actual problem. The ldarg instruction loads a method
argument. ldarg.2 is a shorthand-form for this, it's used to keep the code
size small.
My advice would be for you to use the MethodBody.ExpandMacros() extension
method is Mono.Rocks.dll when you begin working with a method, and
MethodBody.SimplifyMacros() when you're done working with it.
ExpandMacros() will turn ldarg.2 (which doesn't have an operand, because
it's a short form) to ldarg <ParameterReference>, which will now have an
operand of type ParameterReference. That'll give you all the information you
need.
SimplyMacros() will optimize the instructions again, and will use
shorthand-forms whenever possible.
Hope this helps!
