C#语言中的XmlSerializer类的Serialize(Stream,Object)方法举例详解

在对象和 XML 文档之间进行序列化和反序列化操作。 XmlSerializer 使您能够控制如何将对象编码为 XML。

命名空间:   System.Xml.Serialization
程序集:  System.Xml（位于 System.Xml.dll）

下面举个例子说明：

// This is the class that will be serialized.
public class OrderedItem
{
   public string ItemName;
   public string Description;
   public decimal UnitPrice;
   public int Quantity;
   public decimal LineTotal;

   // A custom method used to calculate price per item.
   public void Calculate()
   {
      LineTotal = UnitPrice * Quantity;
   }
}

如何把这个类转换成一个xml文件呢，这时候就需要 XmlSerializer类来处理了。

它的Serialize(Stream,?Object)这个方法，就是用来把一个user类的对象转换成xml文档的。

我们来看一个例子：

using System;
using System.IO;
using System.Xml.Serialization;public class Test{
   public static void Main(string[] args)
   {
      Test t = new Test();
      // Write a purchase order.
      t.SerializeObject("simple.xml");
   }

   private void SerializeObject(string filename)
   {
      Console.WriteLine("Writing With Stream");

      XmlSerializer serializer =
      new XmlSerializer(typeof(OrderedItem));
      OrderedItem i = new OrderedItem();
      i.ItemName = "Widget";
      i.Description = "Regular Widget";
      i.Quantity = 10;
      i.UnitPrice = (decimal) 2.30;
      i.Calculate();

      // Create a FileStream to write with.
      Stream writer = new FileStream(filename, FileMode.Create);
      // Serialize the object, and close the TextWriter
      serializer.Serialize(writer, i);
      writer.Close();
   }
}

所生成的xml文件如下格式：

<?xml version="1.0"?>
 <OrderedItem xmlns:inventory="http://www.cpandl.com" xmlns:money="http://www.cohowinery.com">
   <inventory:ItemName>Widget</inventory:ItemName>
   <inventory:Description>Regular Widget</inventory:Description>
   <money:UnitPrice>2.3</money:UnitPrice>
   <inventory:Quantity>10</inventory:Quantity>
   <money:LineTotal>23</money:LineTotal>
 </OrderedItem>
