c#对象保存Demo

一个将对象保存到文本文档的Demo供大家参考

namespace saveObjectWinForm
{   
    [Serializable]
    class Student
    {
        public string Name { get; set; }
        public int Age { get; set; }
        public string Sex { get; set; }
        public DateTime Birthday { get; set; }
    }
}

namespace saveObjectWinForm
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }
        //保存到文本文件
        private void button1_Click(object sender, EventArgs e)

        }
        //保存二进制序列化形式
