整理一下 .net 对象序列化注意事项：
1. 字段：必须是 public类型
2.属性：只读或者只写的属性不被序列化，只有 可读可写并且赋值的才可以
序列化：
Someclass obj = new SomeClass();
XmlSerializer ser = new XmlSerializer(typeof(Someclass));
StreamWriter writer = new StreamWriter("ser.xml");
ser.Serialize(writer, obj);
writer.Close();
反序列化
FileStream fs = new FileStream("ser.xml", FileMode.Open);
Someclass newObj = (Someclass)ser.Deserialize(fs);
fs.Close();
对于数组亦可，只需将SomeClass换成SomeClass[]即可。
关于在WCF中的序列化
json:DataContractJsonSerializer支持使用以JavaScript 对象标记作为序列化格式
using System.Runtime.Serialization.Json;
Employee e = new Employee(, "Daniel", "Dong");
FileStream writer = new FileStream("sample.xml", FileMode.Create);
DataContractJsonSerilizer ser = new DataContractJsonSerilizer(typeof(Employee));
ser.Serialize(writer, e);
writer.Close();
序列化Employee类的结果
{"Employee":101, "FirstName":"Daniel", "LastName":"Dong"}
xml: 主要讲两种
DataContractSerializer(作为默认的序列化基础方法因为它是WCF的初始序列化结构)、
XmlSerializer(如果你需要支持已有的类型或者自定义序列化而且它们不被DataContractSerializer支持的话，你可能想要使用XmlSerializer.)
Demo: xmlSerializer
using System.Xml.Serialization;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Serialization;
using System.Diagnostics; namespace Chinaer.WcfDemo.ConsoleClient
{
class Program
{
static void Main(string[] args)
{ Person person = new Person()
{
Age = ,
UserPwd = "",
UserName = "郭志奇",
Date = DateTime.Now
}; using (XmlWriter writer = new XmlTextWriter("person.xml", Encoding.UTF8))
{
XmlSerializer serializer = new XmlSerializer(typeof(Person));
serializer.Serialize(writer, person);
} Process.Start("person.xml");
Console.Read();
} /// <summary>
/// 序列化方法
/// </summary>
/// <typeparam name="T"></typeparam>
/// <param name="instace"></param>
/// <param name="fileName"></param>
public static void Serialize<T>(T instace, string fileName)
{
using (XmlWriter writer = new XmlTextWriter(fileName, Encoding.UTF8))
{
XmlSerializer serializer = new XmlSerializer(typeof(T));
serializer.Serialize(writer, instace);
}
Process.Start(fileName);
}
}
[XmlRoot(ElementName="guozhiqi",Namespace="http://www.guozhiqi.com")]
/// <summary>
/// 定义一个实体类 Person
/// </summary>
public class Person
{
private Guid _id; private DateTime _date;
//注意我们没有默认的构造函数
internal double Age { get; set; } //私有字段 年龄
/// <summary>
/// 通过XmlAttributeAttribute 序列化成xml属性
/// </summary>
[XmlAttribute(AttributeName="GuidID",Namespace="http://guidID")]
public Guid ID
{
get { return _id; }
set
{
_id = value;
}
} //公有的随机数
[XmlElement(ElementName="DateTime",Namespace="http://date")]
public DateTime Date
{
set
{
_date = value;
}
get
{
return _date;
}
} public string UserName { get; set; } public string UserPwd { get; set; }
public Person() { }
public Person(double age, Guid id)
{
this.Age = age; }
} }
序列化结果：
<?xml version="1.0" encoding="utf-8"?> <guozhiqi xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" d1p1:GuidID="00000000-0000-0000-0000-000000000000"
xmlns:d1p1="http://guidID" xmlns="http://www.guozhiqi.com">
<DateTime xmlns="http://date">--21T23::13.8584896+:</DateTime>
<UserName>郭志奇</UserName><UserPwd></UserPwd></guozhiqi>
注意：xmlSerializer，对字段、属性序列化 遵循.net 序列化规则，字段是public，属性是可读可写，并且我们还也可以指定名称及命名空间
