C# 操作xml与对象转化用什么方法？

Question

<?xml version="1.0" encoding="UTF-8"?>
<users>
<user id="Rich" name="Rich" password="1" address="33/2 Mary ST Strathfield NSW 2250"/>
<user id="Randy" name="Randy" password="1" address="37/7 Jones ST Summer Hill NSW 2258"/>
<user id="Shelly" name="Shelly" password="1" address="3/2 Kingscross ST city NSW 2250"/>
<user id="Vincent" name="Vincent" password="1" address="36/7 George ST Chippendale NSW 2250"/>
<user id="Jay" name="Jay" password="1" address="33/2 Pancake ST Epping NSW 2250"/>
<user id="Andy" name="Andy" password="1" address="33/2 Jhon ST Telopia NSW 2250"/>
</users>
以上是一个简单的xml文件  定义了一个User的列表
我现在想用一个User类 通过代码把这个xml中的每个<user>结点取出来，放到User类里面也就是说xml与对象的转化  同理，我也需要反过来将User对象的集合转化到一个xml文件中，
请问有没有直接的方法呢？一个个属性读取xml 然后拼凑User对象的方法就免了，因为这种笨办法谁都能想到

.net 提供 xml 的序列化以及反序列化
你可以直接使用 System.Xml.Serialization.XmlSerializer 完成此项功能
DEMO 在：
