C#序列化与反序列化(Serialize,Deserialize)实例详解

using System.IO;
using System.Runtime.Serialization.Formatters.Binary;
[Serializable]
//如果要想保存某个class中的字段,必须在class前面加个这样attribute(C#里面用中括号括起来的标志符)
public class Person
{
public int age;
public string name;
[NonSerialized] //如果某个字段不想被保存,则加个这样的标志
public string secret;
}

classProgram
{
 staticvoid Main(string[] args)
{
Person person = newPerson();
person.age = 18;
person.name = "tom";
person.secret = "i will not tell you";
FileStream stream =newFileStream(@"c:\temp\person.dat",FileMode.Create);
BinaryFormatter bFormat =newBinaryFormatter();
bFormat.Serialize(stream, person);
stream.Close();
}

classProgram
{
staticvoid Main(string[] args)
{
Person person = newPerson();
FileStream stream =newFileStream(@"c:\temp\person.dat",FileMode.Open);
BinaryFormatter bFormat =newBinaryFormatter();
person = (Person)bFormat.Deserialize(stream);
//反序列化得到的是一个object对象.必须做下类型转换
stream.Close();
Console.WriteLine(person.age + person.name + person.secret);
//结果为18tom.因为secret没有有被序列化.
}
