C#.Net2.0 DLL in Delphi2007 nutzen (Com)?

[winx]

Das ist nur ein Ausschnitt aus der Klasse, die komplette ist hier:

Code:

using System;
using System.Collections.Generic;
using System.Text;
using System.Runtime.InteropServices;

namespace DotNetDLL
{
    [ComVisible(true)]
    public class DotNetClass
    {
        /// <summary>
        /// Der Int Wert der Klasse
        /// </summary>
        private int m_ValueInt = 0;

        /// <summary>
        /// Der String der Klasse
        /// </summary>
        private readonly string m_ValueString = String.Empty;

        /// <summary>
        /// Das utilitiy Objekt
        /// </summary>
        private Utility m_Util = new Utility();

        
        /// <summary>
        /// Standardkonstruktor
        /// </summary>
        public DotNetClass()
        {
            m_ValueString = "Hallo";
            m_ValueInt = 7;
            m_Util = new Utility();

        }


        /// <summary>
        /// Konstuktor 2
        /// </summary>
        /// <param name="m_ValueInt">Zahl</param>
        /// <param name="m_ValueString">String</param>
        /// <param name="m_Util">Objekt</param>
        public DotNetClass(int m_ValueInt, string m_ValueString, Utility m_Util)
        {
            this.m_ValueInt = m_ValueInt;
            this.m_ValueString = m_ValueString;
            this.m_Util = m_Util;
        }



        /// <summary>
        /// Der Int Wert der Klasse
        /// </summary>
        public int ValueInt
        {
            get { return m_ValueInt; }
            set { m_ValueInt = value; }
        }


        /// <summary>
        /// Der String der Klasse
        /// </summary>
        public string ValueString
        {
            get { return m_ValueString; }
        }


        public int add(int a,int b)
        {
            return a + b;
        }
    }
}

also daran kanns nicht liegen
