C# 序列化与反序列化几种格式的转换

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;}     }

 

 1  LoginObject loginObject = new LoginObject { Account = account, Password = password }; 2             ExTools.Manage.Class.CScriptSerialize Serialize = new Class.CScriptSerialize(); 3             //将object对象转换为string 4              string strJson=Serialize.ScriptSerialize(loginObject); 5            6             //将object对象转换为xml对象 7             string strJson = Serialize.ScriptSerializeToXML(loginObject); 8             9 10             //转换为list对象11              List<LoginObject> list = Serialize.JSONStringToList<LoginObject>(strJson);12             //将一个xml对象转换为object对象13            strJson = strJson.Substring(1, strJson.Length - 1);14             loginObject = Serialize.JSONXMLToObject<LoginObject>(strJson);15             //将字符串转换为dataTable16             DataTable dt = Serialize.JSONStringToDataTable<LoginObject>(strJson);17             //将字符串转换为object对象18             loginObject = Serialize.ScriptDeserialize<LoginObject>(strJson);
