How can I walk the method call to an Action, Func, or Delegate in introspector for a custom rule?

Question

I'm writing a custom rule to verify the constructor of any control type calls initialize component.

But when I hit these 2 edge cases:

public Form1(int? testInt,bool testBool,bool testBool2)
        : this(false)
    {
        Action init = ( ) => InitializeComponent( );
        init();
    }
    public Form1(int? testInt, bool testBool, bool? testBool2)
        : this(false)
    {
        Action init = InitializeComponent;
        init( );
    }

I can't seem to walk the init call to see that initializeComponent is getting called in these constructors. I know this is an edge case, and unlikely to happen, but I want to learn how to do it.

The reflector IL looks like this:

.method public hidebysig specialname rtspecialname instance void .ctor(valuetype [mscorlib]System.Nullable`1<int32> testInt, bool testBool, bool testBool2) cil managed
{
.maxstack 3

    [0] class [mscorlib]System.Action init,
    [1] class [mscorlib]System.Action CS$<>9__CachedAnonymousMethodDelegateb)

}

}

I'm walking the constructors as such:

        private Dictionary<Method, bool> _methodContainsInitCall;
public void VisitConstructorsRecursive(Method method, Method initializer)
    {
        Debug.Assert(_methodContainsInitCall.ContainsKey(method));
        var toVisit = new List<Method>( );
        foreach (var instruction in method.Instructions.Where(x => x.OpCode==OpCode.Call || x.OpCode== OpCode.Callvirt))
        {

            if (instruction.Value is Method)
            {
                //&&((Method)instruction.Value).FullName.Contains(".#ctor")
                var callMethod =(Method)instruction.Value;
                if (callMethod.FullName.StartsWith("System.Windows.Forms.Form.#ctor"))
                    continue;
                if (callMethod.IsStatic==false) //can not call instance method InitializeComponent in static method
                {
                    toVisit.Add(callMethod);
                }

                //
                //TestLibrary.Form1.#ctor(System.String)
            }
            if (instruction.Value is Method&&((Method)instruction.Value).FullName.EndsWith(".InitializeComponent"))
            {
                if (_constructorFoundInitializeCall.ContainsKey(method))
                    _constructorFoundInitializeCall[method]=true;
                _methodContainsInitCall[method]=true;
                return;
            }

        }
        foreach (var methodCall in toVisit)
        {
            if (_methodContainsInitCall.ContainsKey(methodCall))
            {
                if (_methodContainsInitCall[methodCall])
                {
                    _constructorFoundInitializeCall[initializer]=true;
                    return;
                }
            }
            else
            {
                _methodContainsInitCall.Add(methodCall, false);
                VisitConstructorsRecursive(methodCall, initializer);
            }


        }
    }

when the virtual call to Action.Invoke() happens, it is flagged as virtual and method.Instructions.Count ==0 as well as method.Body.Count==0

so where is my instruction to call the initialize component hiding that I can verify it is actually being called?
