WP7中对本地XML文件的序列化与反序列化

 

1、两个用于序列化和反序列化的类  

 public class Family
    {
        public string FamilyName { get; set; }
        public int FamilyNum { get; set; }

    }

 public class Student
    {
        public int StuID { get; set; }

        public string StuName { get; set; }

        public string StuSchool { get; set; }

        public Family Fa { get; set; }    //属性Fa是Family类的对象
    }

2.XMLFile.Xml 文件的内容

<?xml version="1.0"?>
<ArrayOfStudent xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <Student>
    <StuID>1</StuID>
    <StuName>曹伟</StuName>
    <StuSchool>思远IT</StuSchool>
    <Fa>
      <FamilyName>FamilyOne</FamilyName>
      <FamilyNum>3</FamilyNum>
    </Fa>
  </Student>
  <Student>
    <StuID>2</StuID>
    <StuName>雷敏</StuName>
    <StuSchool>义宏小学</StuSchool>
    <Fa>
      <FamilyName>FamilyTwo</FamilyName>
      <FamilyNum>5</FamilyNum>
    </Fa>
  </Student>
  <Student>
    <StuID>3</StuID>
    <StuName>陈龙</StuName>
    <StuSchool>车胤中学</StuSchool>
    <Fa>
      <FamilyName>FamilyThree</FamilyName>
      <FamilyNum>6</FamilyNum>
    </Fa>
  </Student>
</ArrayOfStudent> 

3、PubXmlSerialize.cs

 public class PubXmlSerialize
    {
        /// <summary>
        /// 对象序列化成 XML String
        /// </summary>
        public static string XmlSerialize<T>(T obj)
        {
            string xmlString = string.Empty;
            XmlSerializer xmlSerializer = new XmlSerializer(typeof(T));
            using (MemoryStream ms = new MemoryStream())
            {
                xmlSerializer.Serialize(ms, obj);
                ms.Position = 0;
                xmlString = new StreamReader(ms).ReadToEnd();

            }
            return xmlString;
        }

        /// <summary>
        /// XML String 反序列化成对象
        /// </summary>
        public static T XmlDeserialize<T>(string xmlString)
        {
            T t = default(T);
            XmlSerializer xmlSerializer = new XmlSerializer(typeof(T));
            using (Stream xmlStream = new MemoryStream(Encoding.UTF8.GetBytes(xmlString)))
            {
                using (XmlReader xmlReader = XmlReader.Create(xmlStream))
                {
                    Object obj = xmlSerializer.Deserialize(xmlReader);
                    t = (T)obj;
                }
            }
            return t;
        }
    }

一、一般对象集的序列化与反序列化

 List<Student> sss = new List<Student>
                {
                  new Student{StuID=1,StuName="张三",StuSchool="school1",Fa=new Family(){FamilyName="name1",FamilyNum=3}},
                  new Student{StuID=1,StuName="李四",StuSchool="school2",Fa=new Family(){FamilyName="name2",FamilyNum=4}}

                };

            string strXml = PubXmlSerialize.XmlSerialize<List<Student>>(sss);                           //序列化
            List<Student> students = PubXmlSerialize.XmlDeserialize<List<Student>>(strXml);  //反序列化

二、Windows Phone7中对本地xml文件的操作

            注:获得本地xml文件学将xml文件的属性"建置动作"设置为Resource

            Stream  str = App.GetResourceStream(new Uri("/PhoneAppSerivable;component/XMLFile.xml", UriKind.Relative)).Stream;
            XDocument doc = XDocument.Load(str);    //加载本地xml文件

        
            List<Student> students = PubXmlSerialize.XmlDeserialize<List<Student>>(doc.ToString());   //反序列化为对象
         

三、使用linq对xml文件进行遍历
            var v = from t in doc.Descendants("Student")
                    select new Student
                    {
                        StuID = int.Parse(t.Element("StuID").Value),
                        StuName = t.Element("StuName").Value,
                        StuSchool = t.Element("StuSchool").Value,
                        Fa = new Family
                        {
                            FamilyName = t.Element("Fa").Element("FamilyName").Value,
                            FamilyNum = int.Parse(t.Element("Fa").Element("FamilyNum").Value),
                        }
                    };
            students = v.ToList();

****:如果XML文件中引用了命名空间，则会出现“xml文件格式不正确”的错误，我们需要得到xml后将命名空间用Replace函数替换为空即可。
