下面小編就為大家?guī)硪黄獪\談C# 序列化與反序列化幾種格式的轉(zhuǎn)換。小編覺得挺不錯(cuò)的，現(xiàn)在就分享給大家，也給大家做個(gè)參考。一起跟隨小編過來看看吧

這里介紹了幾種方式之間的序列化與反序列化之間的轉(zhuǎn)換

首先介紹的如何序列化，將object對(duì)象序列化常見的兩種方式即string和xml對(duì)象;

第一種將object轉(zhuǎn)換為string對(duì)象，這種比較簡(jiǎn)單沒有什么可談的；

public string ScriptSerialize<T>(T t)
    {
      JavaScriptSerializer serializer = new JavaScriptSerializer();
      return serializer.Serialize(t);
    }

第二種將object轉(zhuǎn)換為xml對(duì)象：

public string ScriptSerializeToXML<T>(T t)
    {
      XmlSerializer serializer = new XmlSerializer(typeof(T));
      MemoryStream mem = new MemoryStream();
      XmlTextWriter writer = new XmlTextWriter(mem,Encoding.UTF8);
      XmlSerializerNamespaces ns = new XmlSerializerNamespaces();
      ns.Add("","");
      serializer.Serialize(writer,t,ns);
      writer.Close();
      return Encoding.UTF8.GetString(mem.ToArray());
    }

下面我主要講string對(duì)象反序列化為對(duì)應(yīng)的對(duì)象；

一、將string對(duì)象反序列化為object對(duì)象

public T ScriptDeserialize<T>(string strJson)
    {
      JavaScriptSerializer serializer = new JavaScriptSerializer();
      return serializer.Deserialize<T>(strJson);
    }

二、將string對(duì)象反序列化為list對(duì)象

public List<T> JSONStringToList<T>(string strJson)
    {
      JavaScriptSerializer serializer = new JavaScriptSerializer();
      List<T> objList = serializer.Deserialize<List<T>>(strJson);
      return objList;
    }

三、將string對(duì)象反序列化為datatable對(duì)象

public DataTable JSONStringToDataTable<T>(string strJson)
    {
      DataTable dt = new DataTable();
      if (strJson.IndexOf("[") > -1)//如果大于則strJson存放了多個(gè)model對(duì)象
      {
        strJson = strJson.Remove(strJson.Length - 1, 1).Remove(0, 1).Replace("},{", "};{");
      }
      JavaScriptSerializer serializer = new JavaScriptSerializer();
      string[] items = strJson.Split(';');

      foreach (PropertyInfo property in typeof(T).GetProperties())//通過反射獲得T類型的所有屬性
      {
        DataColumn col = new DataColumn(property.Name,property.PropertyType);
        dt.Columns.Add(col);
      }
      //循環(huán) 一個(gè)一個(gè)的反序列化
      for (int i = 0; i < items.Length; i++)
      {
        DataRow dr = dt.NewRow();
        //反序列化為一個(gè)T類型對(duì)象
        T temp = serializer.Deserialize<T>(items[i]);
        foreach (PropertyInfo property in typeof(T).GetProperties())
        {
          dr[property.Name] = property.GetValue(temp,null);
        }
        dt.Rows.Add(dr);
      }
      return dt;
    }

四、將xml對(duì)象反序列化為object對(duì)象

public T JSONXMLToObject<T>(string strJson)
    {
      XmlDocument xdoc = new XmlDocument();
      try
      {
        xdoc.LoadXml(strJson);
        XmlNodeReader reader = new XmlNodeReader(xdoc.DocumentElement);
        XmlSerializer ser = new XmlSerializer(typeof(T));
        object obj = ser.Deserialize(reader);
        return (T)obj;
      }
      catch
      {
        return default(T);
      }
    }

現(xiàn)在用具體的實(shí)例來如何調(diào)用他們呢?特別要注意的是將xml對(duì)象反序列化objcet對(duì)象

public class LoginObject
  {
     public string Account { get; set;}
     public string Password { get; set;}
   }

LoginObject loginObject = new LoginObject { Account = account, Password = password };
      ExTools.Manage.Class.CScriptSerialize Serialize = new Class.CScriptSerialize();
      //將object對(duì)象轉(zhuǎn)換為string
       string strJson=Serialize.ScriptSerialize(loginObject);
     
      //將object對(duì)象轉(zhuǎn)換為xml對(duì)象
      string strJson = Serialize.ScriptSerializeToXML(loginObject);
      

      //轉(zhuǎn)換為list對(duì)象
       List<LoginObject> list = Serialize.JSONStringToList<LoginObject>(strJson);
      //將一個(gè)xml對(duì)象轉(zhuǎn)換為object對(duì)象
      strJson = strJson.Substring(1, strJson.Length - 1);
      loginObject = Serialize.JSONXMLToObject<LoginObject>(strJson);
      //將字符串轉(zhuǎn)換為dataTable
      DataTable dt = Serialize.JSONStringToDataTable<LoginObject>(strJson);
      //將字符串轉(zhuǎn)換為object對(duì)象
      loginObject = Serialize.ScriptDeserialize<LoginObject>(strJson);
