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);
