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>
<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 ：
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：
{
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);
}
}
