關於XML序列化的簡單例子

關於XML序列化的簡單例子：
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }
//選擇儲存路徑
        private void button1_Click(object sender, EventArgs e)
        {
            saveFileDialog1.Filter = "XML檔案|*.xml";
            if (saveFileDialog1.ShowDialog() == DialogResult.OK)
                textBox1.Text=saveFileDialog1.FileName;
        }
//將類序列化到XML檔案
        private void button2_Click(object sender, EventArgs e)
        {
            if (textBox1.Text == "")
                return;
            mydata newdata = new mydata();
            newdata.myname = "小明";
            newdata.mybirthday = "09-31";
            newdata.age = 23;
            newdata.imageByte = Encoding.Default.GetBytes("999adfklasdjfl".ToCharArray());
            XmlSerializer es=new XmlSerializer(typeof(mydata));
            TextWriter writer = new StreamWriter(textBox1.Text);
            es.Serialize(writer, newdata);
            writer.Close();
        }
//還原序列化XML檔案為類
        private void button3_Click(object sender, EventArgs e)
        {
            XmlSerializer sd = new XmlSerializer(typeof(mydata));
            TextReader drr = new StreamReader(textBox1.Text);
            mydata mm;
            mm = (mydata)sd.Deserialize(drr);
            MessageBox.Show("mm.Name="+mm.myname+"\r\n"+
                             "mm.bothday=" + mm.mybirthday + "\r\n" +
                             "mm.age="+mm.age+"\r\n"+
                             "mm.imageByte="+Encoding.Default.GetString(mm.imageByte));
        }
    }
//the class to serializer
    public class mydata
    {
        public string myname;
        public string mybirthday;
        public int age;
        public byte[] imageByte;
    }
