I dont think marshal.sizeof() wroks for managed objects!?
does it?

It works for value types pretty well ;) For reference types you would need
to use unsafe code.

        struct Foo {
            public int bar;
            public int test;
            public string str;
        }
        static void Main(string[] args) {
            int foo;
            Console.WriteLine(Marshal.SizeOf(typeof(int)));
            Console.WriteLine(Marshal.SizeOf(typeof(Foo)));
        }


Cheers,

Greg
