XmlSerializer序列化实体类来操作xml文件

  

     在.net当中使用XmlSerializer类可以将实体类进行序列化，可以比较方便的操作xml文件。

     其中xml文件中不同的节点对应不同的实体类，相同有序的节点对应着实体类的集合类。demo如下:

     books.xml 文件 ：

<? xml version = " 1.0 "  encoding = " utf-8 "   ?>
< books >
   < book bookname = " c++语言编程 "  author = " AAAA "  Date = " 2009 " ></ book >
   < book bookname = " Java语言编程 "  author = " BBBB "  Date = " 2009 " ></ book >
   < book bookname = " C#语言编程 "  author = " CCCC "  Date = " 2009 " ></ book >
</ books >

      与之相对应的实体类及操作

     Books.cs ：

Books.cs
    [XmlRoot("books")]
    public class Books:List<Book>
    {
         public static Books LoadConfig(string file)
        {
            XmlSerializer xs = new XmlSerializer(typeof(Books));
            StreamReader sr = new StreamReader(file);
            Books config = xs.Deserialize(sr) as Books;
            sr.Close();

            return config;
        }
        public void SaveConfig(string file)
        {
            XmlSerializer xs = new XmlSerializer(typeof(Books));
            StreamWriter sw = new StreamWriter(file);
            xs.Serialize(sw, this);
            sw.Close();
        }
    }


    [XmlType("book")] // used for books.Items
    public class Book
    {
        private string _bookname;
        [XmlAttribute("bookname")]
        public string BookName
        {
            get { return this._bookname; }
            set { this._bookname = value; }
        }
        private string _author;
        [XmlAttribute("author")]
        public string Author
        {
            get { return this._author; }
            set { this._author = value; }
        }
        private string _date;
        [XmlAttribute("Date")]
        public string Date
        {
            get { return this._date; }
            set { this._date = value; }
        }
    }

主程序调用：

Form1
    public partial class Form1 : Form
    {
        private Books books = null;
        string xmlpath = "";
        public Form1()
        {
            InitializeComponent();
            xmlpath = Application.StartupPath + @"\books.xml";
            books = Books.LoadConfig(xmlpath);
        }

        private void btnDisplay_Click(object sender, EventArgs e)
        {
            this.bindingXmlSource.DataSource = books;
            this.dgvShowData.DataSource = bindingXmlSource;
        }

        private void btnSave_Click(object sender, EventArgs e)
        {
            books = this.bindingXmlSource.DataSource as Books;
            books.SaveConfig(xmlpath);
        }
    }
