I think it should work too.


Here is my solution:

import tango.io.Stdout;
public class FooBar {
        public int b = 8;
}

void main() {

        int c;
        FooBar foo = new FooBar();
        asm {
                mov  EBX,[foo];
                mov ECX,dword ptr[EBX+8];
                mov c,ECX;
        }
        Stdout("c: ")(c).newline;
}
