定义服务器端Controlinfo类型

本文是我在书上抄的
我们需要在服务器端定义一个表示控件信息的类:ControInfo,完整代码如下.
Public class ControlInfo
{      
        private string _name;
        private string _description;
        private int _id;

        [DataObjectField(true, true)]
        public int Id
        {
            get { return _id; }
            set { _id = value; }
        }
        [DataObjectField(false)]
        [DefaultValue("New Control")]
        publish string Name
        {
            get { return _name; }
            set { _name = value; }
        }
        [DataObjectField(false)]
        [DefaultValue("Default Description")]
        public string Description
        {
            get { return _description; }
            set { _description = value; }
        }
        public ControlInfo()
        {
            _id = -1;
        }
        public ControlInfo(int id, string name, string description)
        {
            _id = id;
            _name = name;
            _description = description;
        }
