序列化与反序列化

继承BinaryFormatter()类

        [Serializable]//允许这个对象序列化
        public class Person
        {
            public int Id { get; set; }
            public string Name { get; set; }
            public int Age { get; set; }
        }

序列化

            BinaryFormatter binaryFormatter = new BinaryFormatter();

            if (!File.Exists("person.bin"))//判断是否读取到这个文件
            {
                Person person = new Person()//给对象赋值
                {
                    Id = 1,
                    Name = "Test",
                    Age = 23
                };
                //将对象序列化为二进制数据

                using (FileStream stream = new FileStream("person.bin", FileMode.Create))
                {
                    binaryFormatter.Serialize(stream, person);
                    
                }

                
            }

反序列化

            //从文件反序列化
            using (FileStream stream1 = new FileStream("person.bin", FileMode.Open))
            {

                Person person1 = (Person)binaryFormatter.Deserialize(stream1);
                
                //var person1 = binaryFormatter.Deserialize(stream1);
                Console.WriteLine("111");
                Console.WriteLine(person1);
                ListViewItem item = new ListViewItem();
                item.SubItems[0].Text = person1.Id.ToString();
                item.SubItems.Add(person1.Name);
                item.SubItems.Add(person1.Age.ToString());
                listView1.Items.Add(item);
            }
