C#序列化

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dataTable
16             DataTable dt = Serialize.JSONStringToDataTable<LoginObject>(strJson);
17             //将字符串转换为object对象
18             loginObject = Serialize.ScriptDeserialize<LoginObject>(strJson);
