C# 序列化與反序列化幾種格式的轉換

第一種將object轉換爲string對象，這種比較簡單沒有什麼可談的；

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

第二種將object轉換爲xml對象：

 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對象反序列化爲對應的對象；

一、將string對象反序列化爲object對象

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

二、將string對象反序列化爲list對象

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

三、將string對象反序列化爲datatable對象

  public DataTable JSONStringToDataTable<T>(string strJson)
        {
            DataTable dt = new DataTable();
            if (strJson.IndexOf("[") > -1)//如果大於則strJson存放了多個model對象
            {
                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 一個一個的反序列化
            for (int i = 0; i < items.Length; i++)
            {
                DataRow dr = dt.NewRow();
                //反序列化爲一個T類型對象
                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對象反序列化爲object對象

 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);
            }
        }

現在用具體的實例來如何調用他們呢?特別要注意的是將xml對象反序列化objcet對象

 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             //將object對象轉換爲string
 4              string strJson=Serialize.ScriptSerialize(loginObject);
 5           
 6             //將object對象轉換爲xml對象
 7             string strJson = Serialize.ScriptSerializeToXML(loginObject);
 8            
 9 
10             //轉換爲list對象
11              List<LoginObject> list = Serialize.JSONStringToList<LoginObject>(strJson);
12             //將一個xml對象轉換爲object對象
13            strJson = strJson.Substring(1, strJson.Length - 1);
14             loginObject = Serialize.JSONXMLToObject<LoginObject>(strJson);
15             //將字符串轉換爲dataTable
16             DataTable dt = Serialize.JSONStringToDataTable<LoginObject>(strJson);
17             //將字符串轉換爲object對象
18             loginObject = Serialize.ScriptDeserialize<LoginObject>(strJson);
