发现一个问题，各位兄弟们看看。偶是新手，多多指教啊。

实体类以及相关接口定义如下：

   public interface IA {
        int UID { get; }

        string Name { get;        set;        }
    }

    public interface IChem : ISerialObject    {
        string RptName { get; set; }
    }

    public class Chem : IChem    {
        public Chem()        {
            id = ++no;
            Name = id.ToString();
            RptName = Name + Name;
        }
        private static int no = 0;
        private int id;
        public int UID        {
            get{           return id;            }

        }

        private string name;
        public string Name        {
            get { return name; }
            set { name = value; }
        }

        private string rptName;
        public string RptName        {
            get { return rptName; }
            set { rptName = value; }
        }

        public static IChem Create()
        {
            return new Chem();
        }
    }

窗口有2个TextBox用来绑定数据源

     private BindingSource bindSrc = new BindingSource();//定义为窗口成员变量

      private void Form1_Load(object sender, EventArgs e)
        {

            BindingList<IChem> curr = new BindingList<IChem>();
            curr.Add( Chem.Create() );
            curr.Add(Chem.Create());

            bindSrc.DataSource = curr;

            ISerialObject d = (ISerialObject)curr[0];
            IChem f = (IChem)d;
            f.Name = "22";
            
            Binding nameBinding = this.textBox1.DataBindings.Add("Text", bindSrc, "RptName", true);
            nameBinding = this.textBox2.DataBindings.Add("Text", bindSrc, "Name", true);//异常 ，

}

我分析了下，主要是如果接口类Name不可见，无法绑定。怎么解决
