语言转换下,该怎么处理

语言转换下
以下代码是C#中实现了调用COM组件的接口ICAMenu，然后调用它的两个函数AddMenu和doFunction,
求转换为VB语言的

C# code

    //[InterfaceType(ComInterfaceType.InterfaceIsDual)]    public interface Cshaddmen : ICAMenu//接口继承    {         void AddMenu(out object pMenuIndex, out string pName);//函数声明         void doFunction(object para);    }     [Guid("5CAE1D52-83BC-4ad4-AC6D-AEB2E357C886")]    [ProgId("ClbMenu.CSetMen")]    public class CSetMen :Cshaddmen  //使用继承后的接口Cshaddmen     {        public CSetMen()        {                 }        public void AddMenu(out object pMenuIndex, out string pName)        {            short[] aa = new short[2] { 5, 0};            pMenuIndex = aa;            pName = "c# menu";        }        public void doFunction(object para)        {        }    }
