XML序列化

今天写文件时,突然忘了这么一个重要的方法..  记下来吧/

 

 

// 调用
DeSerializeDocument("d:\\books.xml");

  public MyRootClass DeSerializeDocument(string filename)  
        {

            XmlSerializer s = new XmlSerializer(typeof(MyRootClass));
             TextReader myRead = new StreamReader(filename);
           MyRootClass obj =  s.Deserialize(myRead) as MyRootClass;
           return obj;
        }

 public void SerializeDocument(string filename)   
        {            // Creates a new XmlSerializer.          

            XmlSerializer s =      new XmlSerializer(typeof(MyRootClass));       
            // Writing the file requires a StreamWriter.          
           
            TextWriter myWriter = new StreamWriter(filename);          
            // Creates an instance of the class to serialize.         
            
            MyRootClass myRootClass = new MyRootClass();                   
            //create items        
            Item item1 = new Item();           
            // Sets the objects' properties.          
            item1.ItemName = "Widget1";        
           
            item1.ItemCode = "w1";      
            item1.ItemPrice = 231;    
            item1.ItemQuantity = 3;          


            Item item2 = new Item();        
            item2.ItemName = "Widget2";            
            item2.ItemCode = "w2";        
            item2.ItemPrice = 800;       
            item2.ItemQuantity = 2;             // Sets the class's Items property to the list.    
            myRootClass.Items.Add(item1);          
            myRootClass.Items.Add(item2);             /* Serializes the class, writes it to 

disk, and closes                the TextWriter. */          
            s.Serialize(myWriter, myRootClass);           
            myWriter.Close();       
        
        }
    }

    [Serializable]
    public class MyRootClass
    {

        public MyRootClass()
        {
            items =new List<Item>();
        }

        private List<Item> items;
        
        public List<Item> Items
        {
            get { return items; }

            set { items = value; }
        }
    }


    public class Item
    {
        public string ItemName;

        public string ItemCode;

        public decimal ItemPrice; 
        
        public int ItemQuantity;
