这里介绍了几种方式之间的序列化与反序列化之间的转换

首先介绍的如何序列化，将object对象序列化常见的两种方式即string和xml对象;

第一种将object转换为string对象，这种比较简单没有什么可谈的；


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

第二种将object转换为xml对象：


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());
    }

下面我主要讲string对象反序列化为对应的对象；

一、将string对象反序列化为object对象


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

二、将string对象反序列化为list对象


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

三、将string对象反序列化为datatable对象


public DataTable JSONStringToDataTable<T>(string strJson)
    {
      DataTable dt = new DataTable();
      if (strJson.IndexOf("[") > -1)//如果大于则strJson存放了多个model对象
      {
        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())//通过反射获得T类型的所有属性
      {
        DataColumn col = new DataColumn(property.Name,property.PropertyType);
        dt.Columns.Add(col);
      }
      //循环 一个一个的反序列化
      for (int i = 0; i < items.Length; i++)
      {
        DataRow dr = dt.NewRow();
        //反序列化为一个T类型对象
        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、将xml对象反序列化为object对象


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);
      }
    }

现在用具体的实例来如何调用他们呢?特别要注意的是将xml对象反序列化objcet对象


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();
      //将object对象转换为string
       string strJson=Serialize.ScriptSerialize(loginObject);
      //将object对象转换为xml对象
      string strJson = Serialize.ScriptSerializeToXML(loginObject);
      //转换为list对象
       List<LoginObject> list = Serialize.JSONStringToList<LoginObject>(strJson);
      //将一个xml对象转换为object对象
      strJson = strJson.Substring(1, strJson.Length - 1);
      loginObject = Serialize.JSONXMLToObject<LoginObject>(strJson);
      //将字符串转换为dataTable
      DataTable dt = Serialize.JSONStringToDataTable<LoginObject>(strJson);
      //将字符串转换为object对象
      loginObject = Serialize.ScriptDeserialize<LoginObject>(strJson);
