這里介紹了幾種方式之間的序列化與反序列化之間的轉(zhuǎn)換
首先介紹的如何序列化，將object對(duì)象序列化常見(jiàn)的兩種方式即string和xml對(duì)象;
第一種將object轉(zhuǎn)換為string對(duì)象，這種比較簡(jiǎn)單沒(méi)有什么可談的；
public string ScriptSerialize<T>(T t)
{
JavaScriptSerializer serializer = new JavaScriptSerializer();
return serializer.Serialize(t);
}
第二種將object轉(zhuǎn)換為xml對(duì)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(duì)象反序列化為對(duì)應(yīng)的對(duì)象；
一、將string對(duì)象反序列化為object對(duì)象
public T ScriptDeserialize<T>(string strJson)
{
JavaScriptSerializer serializer = new JavaScriptSerializer();
return serializer.Deserialize<T>(strJson);
}二、將string對(duì)象反序列化為list對(duì)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(duì)象反序列化為datatable對(duì)象
public DataTable JSONStringToDataTable<T>(string strJson)
{
DataTable dt = new DataTable();
if (strJson.IndexOf("[") > -1)//如果大于則strJson存放了多個(gè)model對(duì)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(guò)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(huán) 一個(gè)一個(gè)的反序列化
for (int i = 0; i < items.Length; i++)
{
DataRow dr = dt.NewRow();
//反序列化為一個(gè)T類型對(duì)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(duì)象反序列化為object對(duì)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(xiàn)在用具體的實(shí)例來(lái)如何調(diào)用他們呢?特別要注意的是將xml對(duì)象反序列化objcet對(duì)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(duì)象轉(zhuǎn)換為string
4 string strJson=Serialize.ScriptSerialize(loginObject);
5
6 //將object對(duì)象轉(zhuǎn)換為xml對(duì)象
7 string strJson = Serialize.ScriptSerializeToXML(loginObject);
8
9
10 //轉(zhuǎn)換為list對(duì)象
11 List<LoginObject> list = Serialize.JSONStringToList<LoginObject>(strJson);
12 //將一個(gè)xml對(duì)象轉(zhuǎn)換為object對(duì)象
13 strJson = strJson.Substring(1, strJson.Length - 1);
14 loginObject = Serialize.JSONXMLToObject<LoginObject>(strJson);
15 //將字符串轉(zhuǎn)換為dataTable
16 DataTable dt = Serialize.JSONStringToDataTable<LoginObject>(strJson);
17 //將字符串轉(zhuǎn)換為object對(duì)象
18 loginObject = Serialize.ScriptDeserialize<LoginObject>(strJson);

難過(guò)

圍觀
無(wú)聊
