winform里面怎么重写DateTimePicker控件?

Question

Value是DateTime,它是一个值类型,不可以为空的.
如果真要这样,应该可以写为
    class MyDateTimePicker:DateTimePicker
    {
        public new Object Value
        {
            get { return this.Value; }
            set
            {
                if (value != null)
                {
                    base.Value = (DateTime)value;
                }
                else
                    this.Value = value;
            }
        }
    }
