利用XmlSerializer类的特性读写WITSML

随着XML的越来越流行，读写XML成为了一项基本的技能。在.Net平台下，XmlSerializer类可以将对象模型直接序列化为XML文件，并支持反向序列化。这样的特性无疑给程序员带来了极大的便利。

在石油行业，WITSML(井场信息传输标准标记语言)日益取代WITS，为新一代传输标准奠定了语言基础。如何读写WITSML迫在眉睫。

这里将结合这样的技术和这样的需求，给出一个简单的示例，供相关人士参考批评。

1. 需要引入System.IO和System.Xml.Serialization两个命名空间。
2. 建立相应的类。
3. 为对象赋值。
4. 创建序列化对象
5. 生成并写入XML文件
6. 读取并获取XML文件中的对象
7. 输出

代码示例如下：
