namespace 对象的序列化与反序列化

{

public partial class Form1 : Form

{

public Form1()

{

InitializeComponent();

}

private void Form1_Load(object sender, EventArgs e)

{

}

private void button1_Click(object sender, EventArgs e)

{

Student student = new Student()

{

Name = textBox1.Text.Trim(),

Age = Convert.ToInt32(textBox2.Text.Trim()),

Birthday = Convert.ToDateTime(textBox3.Text)

};

FileStream fs = new FileStream(@"D:\用户目录\Desktop\2.txt", FileMode.Create);

BinaryFormatter bf = new BinaryFormatter(); //创建2进制格式化器

bf.Serialize(fs,student);

fs.Close();

//StreamWriter sw = new StreamWriter(fs, Encoding.UTF8);

//sw.WriteLine(student.Name);

//sw.WriteLine(student.Age);

//sw.WriteLine(student.Birthday);

//sw.Close();

//fs.Close();

//MessageBox.Show("成功写入");

}

private void button2_Click(object sender, EventArgs e)

{

FileStream fs = new FileStream(@"D:\用户目录\Desktop\2.txt", FileMode.Open);

BinaryFormatter bf = new BinaryFormatter();//定义了一个二进制格式化器

Student student = (Student)bf.Deserialize(fs);//将文件对象fs的用二进制格式化器反序列化；因为反序列化之后的对象是Object类型的，在这里将他强制类型转换为Student类型

textBox1.Text = student.Name;

textBox2.Text = student.Age.ToString();

textBox4.Text = student.Birthday.ToString();

fs.Close();

// StreamReader sr = new StreamReader(fs);

//textBox1.Text=sr.ReadLine();

//textBox2.Text = sr.ReadLine();

//textBox3.Text = sr.ReadLine();

// sr.Close();

// fs.Close();

}
