XML序列化

实体类:

[System.Xml.Serialization.XmlRootAttribute("ProductSample")]//此行注释掉仍能正常串行化
    public class Product
    {
        private int prodId;
        private string prodName;
        private int catId;
        private Decimal unitPrice;
        private bool discont;
        private int disc;

        //added the Discount attribute
        [XmlAttributeAttribute(AttributeName = "Discount")]
        public int Discount
        {
            get { return disc; }
            set { disc = value; }
        }

        [XmlElementAttribute()]//此行注释掉仍能正常串行化
        public int ProductID
        {
            get { return prodId; }
            set { prodId = value; }
        }
        [XmlElementAttribute()]
        public string ProductName
        {
            get { return prodName; }
            set { prodName = value; }
        }
        [XmlElementAttribute()]
        public int CategoryID
        {
            get { return catId; }
            set { catId = value; }
        }
        [XmlElementAttribute()]
        public Decimal UnitPrice
        {
            get { return unitPrice; }
            set { unitPrice = value; }
        }
        [XmlElementAttribute()]
        public bool Discontinued
        {
            get { return discont; }
            set { discont = value; }
        }
    }

序列化与反序列化测试:

public class Test
    {
        /**//// <summary>
        /// 序列化实体对象
        /// </summary>
        public static void Write()
        {
            Product product = new Product();

            //set some properties
            product.ProductID = 200;
            product.CategoryID = 100;
            product.Discontinued = false;
            product.ProductName = "Serialize Objects";
            product.UnitPrice = 1000;

            // 串行化
            TextWriter tw = new StreamWriter("product.xml");
            XmlSerializer xs = new XmlSerializer(typeof(Product));
            
            xs.Serialize(tw, product);    // 序列化对象
            tw.Close();
        }
        /**//// <summary>
        /// 从Xml文件中获取实体对象
        /// </summary>
        public static void Read()
        {
            TextReader tr = new StreamReader("product.xml");
            XmlSerializer xs = new XmlSerializer(typeof(Product));
            Product product = (Product)xs.Deserialize(tr);    // 反序列化对象
            //Console.WriteLine(product.ProductName);
        }
        static void Main()
        {
            Test.Write();
            Test.Read();
        }

序列化成的XML文件(product.xml)

<?xml version="1.0" encoding="utf-8"?>
<ProductSample xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" Discount="0">
  <ProductID>200</ProductID>
  <ProductName>Serialize Objects</ProductName>
  <CategoryID>100</CategoryID>
  <UnitPrice>1000</UnitPrice>
  <Discontinued>false</Discontinued>
</ProductSample>
