以上为Person类
string path = @"D:\DiduTimes\CsharpSelfDoc\20121006\456.txt";//读取别人序列化后的记事本文档
//比如456记事本中存的是"  >Lesson2, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null Lesson2.Person _name_gender_age_adress_email_typeofblood_job_graduateSchool 绐﹀Ξ濠? 濂? 鍖椾含 douniwan@itcast.cn o 瀛︾敓鍖楀ぇ";可以将引号里的内容粘贴到记事本文档中并命名为456.txt
using (FileStream fs = new FileStream(path, FileMode.Open, FileAccess.Read, FileShare.Read))//可读
{
BinaryFormatter bf = new BinaryFormatter();
p = (Person)bf.Deserialize(fs);//反序列化,用里氏转换为Person类
}
Console.WriteLine(p.Name);
Console.WriteLine(p.Age);
Console.WriteLine(p.Gender);
Console.WriteLine(p.Typeofblood);
Console.WriteLine(p.Adress);
Console.WriteLine(p.Email);
Console.WriteLine(p.Job);
Console.WriteLine(p.GraduateSchool);//输出实例化对象的信息
Console.ReadKey();
序列化时,可写状态,bf.Serialize(fs, p);序列化时,参数除了要实例化后的文件流,还要输入实例化的对象名
反序列化时,可读状态,p = (Person)bf.Deserialize(fs);反序列化,只需要实例化后的文件流,但是需要里氏转换类型,然后用实例化的对象名来接收,通过对象.属性输出显示所存储的值.
