//xml序列化方法  public sealed class ConfigurationManager        {            //单件模式  定义一个私有的构造函数 private 定义一个私有的类的对象            private static HumanResource m_humanResource = null;            private ConfigurationManager() { }            public static HumanResource Get(string path)            {                if (m_humanResource == null)                {                    FileStream fs = null;                    try                    {                        //序列化一个对象 HumanResource                        XmlSerializer xs = new XmlSerializer(typeof(HumanResource));                        fs = new FileStream(path, FileMode.Open, FileAccess.Read);                        m_humanResource = (HumanResource)xs.Deserialize(fs);                        fs.Close();                        return m_humanResource;                    }                    //处理异常                    catch                    {                        if (fs != null)                            fs.Close();                        throw new Exception("Xml deserialization failed!");                    }                }                else                 {                    return m_humanResource;                }                                    }            //将对象序列化成xml文件            public static void Set(string path,HumanResource humanResource)            {                FileStream fs = null;                if (humanResource == null)                {                    throw new Exception("Parameter humanResource is null!");                                }                try                {                    //序列化对象 typeof要序列化对象的列名                    XmlSerializer xs=new XmlSerializer(typeof(HumanResource));                    fs = new FileStream(path,FileMode.Create,FileAccess.Write);                    xs.Serialize(fs, humanResource);                    m_humanResource = null;                    fs.Close();                                    }                catch {                    if (fs != null)                        fs.Close();                    throw new Exception("Xml serialization failed!");                                }                                    }                 }

序列化后产生xml文件格式如下:

         <?xml version="1.0" ?>         <humanResource  record="2">        <worker number="001">       <infoItem name="name">Michale</infoItem>      <infoItem name="sex">male</infoItem>      <infoItem name="age">25</infoItem>                   </worker>        <worker number="002">                       <infoItem name="name">Surce</infoItem>                         <infoItem name="sex">male</infoItem>                        <infoItem name="age">28</infoItem>               </worker>            </humanResource>
