一个将对象保存到文本文档的Demo供大家参考
这里写图片描述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)
{
Student student = new Student()
{
Name = this.name.Text,
Age = Convert.ToInt32(this.age.Text),
Sex = this.sex.Text,
Birthday = Convert.ToDateTime(this.brithday.Text),
};
FileStream fs = new FileStream("newObject.txt",FileMode.Create);
StreamWriter sw = new StreamWriter(fs);
sw.WriteLine(student.Name);
sw.WriteLine(student.Age);
sw.WriteLine(student.Sex);
sw.WriteLine(student.Birthday);
sw.Close();
fs.Close();
}
//读取文本文件
private void button2_Click(object sender, EventArgs e)
{
FileStream fs = new FileStream("newObject.txt", FileMode.Open);
StreamReader sr = new StreamReader(fs);
Student student = new Student()
{
Name = sr.ReadLine(),
Age = Convert.ToInt32(sr.ReadLine()),
Sex = sr.ReadLine(),
Birthday = Convert.ToDateTime(sr.ReadLine()),
};
sr.Close();
fs.Close();
this.age.Text = (student.Age).ToString();
this.name.Text = student.Name;
this.brithday.Text = student.Birthday.ToString();
this.sex.Text = student.Sex;
}
//保存二进制序列化形式
private void button3_Click(object sender, EventArgs e)
{
//二进制序列化
Student student = new Student()
{
Name = this.name.Text,
Age = Convert.ToInt32(this.age.Text),
Sex = this.sex.Text,
Birthday = Convert.ToDateTime(this.brithday.Text),
};
//创建文件流
FileStream fs = new FileStream("newObject.stu", FileMode.Create);
//创建二进制格式化器
BinaryFormatter formatter = new BinaryFormatter();
//调用序列化方法
formatter.Serialize(fs, student);
fs.Close();
}
//读取二进制序列化形式
private void button4_Click(object sender, EventArgs e)
{
FileStream fs = new FileStream("newObject.stu", FileMode.Open);
BinaryFormatter formatter = new BinaryFormatter();
Student student = (Student)formatter.Deserialize(fs);
fs.Close();
this.age.Text = (student.Age).ToString();
this.name.Text = student.Name;
this.brithday.Text = student.Birthday.ToString();
this.sex.Text = student.Sex;
}
}
}
