C#是不是同时有IDispose和IDisposable这两个接口?
我下面的代码编译有错:

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;



namespace TestIDispose

{

    public class Program : System.IDisposable

    {

        public override void Dispose()

        {

            Dispose(true);

            //GC.SuppressFinalize(this);

            GC.Collect();

        }



        void Dispose(bool disposing)

        {

        }



        ~Program()

        {

            Dispose();

        }



        static void Main(string[] args)

        {

        }

    }

}

错误提示:
