序列化与反序列化

建立Man.cs

using System.Xml.Serialization;

 

///<summary>

///Man 的摘要说明

///</summary>

 

  [Serializable]

 

    public class Man

    {

 

    

 

         public Man() {

        

        

         }

       [XmlElement("Man_Age")]

         public int Age

         {

             get;

             set;

 

         }

 

         public string Name

         {

             get;

             set;

         }

 

         public string tel

         {

             get;

             set;

         }

        public Man(int Age, string Name ,string tel)

        {

 

            this.Age = Age;

            this.Name = Name;

            this.tel = tel;

 

        }

        public string Show()

        {

 

          return String.Format(" Name : {0}  Age: {1}  tel  :{2}", this.Name, this.Age,this.tel);

        }

        public void AddData(int Age, string Name, string tel)

        {

            this.Age = Age;

            this.Name = Name;

            this.tel = tel;

 

        }

    }

 

1.二进制格式序列化 

  首先引入

using System.Runtime.Serialization.Formatters.Binary;

 

然后通过

 

 

        string Path = "C:\\man.text";

 

        Man m=new Man (18,"小王1","18618618618");

 

        FileStream fs = new FileStream(Path, FileMode.Create);

        BinaryFormatter formatter = new BinaryFormatter();

        formatter.Serialize(fs,m);

        fs.Close();

 

二进制序列化反序列化

 

  

  

        string Path = "C:\\man.text";

        Man m = null;

        FileStream fs = new FileStream(Path,FileMode.Open);

        BinaryFormatter formatter = new BinaryFormatter();

        m = formatter.Deserialize(fs) as Man ;//

        fs.Close();

        return  m.Show();

 

 

 

2.XML序列化

    

 

   

        string Path = "C:\\man.xml";

 

        Man m = new Man();

        m.AddData(18, "小王333", "18618618618");

 

        using (StreamWriter fs = new StreamWriter (Path))

        {

 

            XmlSerializer xmlSerializer = new XmlSerializer(m.GetType());

        

            xmlSerializer.Serialize(fs, m);

         

         

 

        }

xml反序列化

 

        string Path = "C:\\man.xml";

        Man m = new Man ();

        FileStream fs = new FileStream(Path,FileMode.Open);

        XmlSerializer xmlSerializer = new XmlSerializer(m.GetType());

       

       

        m = xmlSerializer.Deserialize(fs) as Man ;//

        fs.Close();

        return  m.Show();

插曲：  可以通过       [NonSerialized]  对对象中的的部分数据取消序列化 做到部分暴露

       如果声明一个类 而没有共有字段 那么这个类进行xml序列化的时候  将无法把数据写入xml文件

 public class XMLserializeHelp
    {

        public static void Serialize<T>(string path, T t) where T:class
        {
            using (StreamWriter sw = new StreamWriter(path))
            {
                XmlSerializer xml = new XmlSerializer(t.GetType());
                xml.Serialize(sw, t);
            }
        }

        public static T Deserialize<T>(string path) where T:class
        {
            T t = default(T);
            FileStream fs = new FileStream(path, FileMode.Open);
            XmlSerializer xmlSerializer = new XmlSerializer(t.GetType());
            t = xmlSerializer.Deserialize(fs) as T;
            fs.Close();
            return t;
        }
    }

 反序列化输出XML：

  反序列化基类：

  

 public class BaseApi : System.Web.UI.Page
    {
         /// <summary>
        /// 反序列化
        /// </summary>
        /// <param name="type"></param>
        /// <param name="xml"></param>
        /// <returns></returns>
        public static object Deserialize(Type type,string strXml) 
        {

            using (StringReader sr = new StringReader(strXml))
            {
                XmlSerializer xmldes = new XmlSerializer(type);
                return xmldes.Deserialize(sr) ;
            }
        }
        

        /// <summary>
        /// 序列化
        /// </summary>
        /// <param name="type">类型</param>
        /// <param name="obj">对象</param>
        /// <returns></returns>
        public static string Serializer(object obj,Type type)
        {
        
            MemoryStream Stream = new MemoryStream();
            XmlSerializer xml = new XmlSerializer(type);
            try
            {
                //序列化对象
                xml.Serialize(Stream, obj);
            }
            catch (InvalidOperationException)
            {
                throw;
            }
            Stream.Position = 0;
            StreamReader sr = new StreamReader(Stream);
            string str = sr.ReadToEnd();
            sr.Dispose();
            Stream.Dispose();
            return str;
        }

    }

定义 输出XML格式对象，同时指定字段  输出 <![CDATA[ ]]> 格式

 [Serializable]
    public class News
    {
        public News() { }
        public int id { get; set; }
        public string title { get; set; }
        [XmlIgnore]
        public string content { get; set; }
        [XmlElement("text_content")]
        public XmlNode text_content 
        {
            get
            {
                return new XmlDocument().CreateCDataSection(this.content);
            }
            set
            {
                this.content = value.Value;
            }
        }
    }

输出：

 public partial class news_api : BaseApi
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            string method = Request.QueryString["method"];
            switch (method)
            {
                case "get_content":
                    get_content(int.Parse(Request.QueryString["id"]));
                    break;
            }
        }

        public void get_content(int id)
        {
            News model = new News();
            model.content = "rhythmk";
            model.id = id;
            model.title = "测试XML ";
            Response.ContentType = "text/xml";
            Response.Write(Serializer(model,typeof(News)));
            Response.End();

        }
    }

 备注:

调整了基类方法写法：

  /// <summary>
        /// 反序列化
        /// </summary>
        /// <param name="type"></param>
        /// <param name="xml"></param>
        /// <returns></returns>
        public static T Deserialize<T>(string strXml) where T:class
        {

            using (StringReader sr = new StringReader(strXml))
            {
                XmlSerializer xmldes = new XmlSerializer(typeof(T));
                return xmldes.Deserialize(sr) as T;
            }
        }
        

        /// <summary>
        /// 序列化
        /// </summary>
        /// <param name="type">类型</param>
        /// <param name="obj">对象</param>
        /// <returns></returns>
        public static string Serializer<T>(object obj)
        {

            T t = (T)obj;
            MemoryStream Stream = new MemoryStream();
            XmlSerializer xml = new XmlSerializer(t.GetType());
            try
            {
                //序列化对象
                xml.Serialize(Stream, obj);
            }
            catch (InvalidOperationException)
            {
                throw;
            }
            Stream.Position = 0;
            StreamReader sr = new StreamReader(Stream);
            string str = sr.ReadToEnd();
            sr.Dispose();
            Stream.Dispose();
            return str;
        }
