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);
