     也可以在類中添加帶這樣標記的屬性,而後在xml中會以 Gather_Article的屬性出現 <Gather_Article Url="" Coding=""

  [XmlAttribute("Url")]
        public string Url
        {
            get;
            set;
        }
        [XmlAttribute("Coding")]
        public string Coding
        {
            get;
            set;
        }
