将业务实体组件序列化为二进制格式

        EmployeeEntity employee = new EmployeeEntity();
        employee.EmployeeNumber = "1234";
        employee.FirstName = "lincoln";
        employee.LastName = "lee";
        employee.InputDateTime = DateTime.Now;
        EmployeeEntity employee1 = new EmployeeEntity();
        employee1.EmployeeNumber = "2222";
        employee1.FirstName = "isabel";
        employee1.LastName = "lv";
        employee1.InputDateTime = DateTime.Now;
        employee1.Nickname = "darling";

// 创建 BinaryFormatter 对象，用于序列化 EmployeeEntity 类型的对象

        BinaryFormatter formatter = new BinaryFormatter();

        // 将 EmployeeEntity 对象序列化为名为“MyBinaryEmployeeEntity.dat”的二进制文件

        FileStream stream = File.Create("MyBinaryEmployee.dat");
        formatter.Serialize(stream, employee);
        formatter.Serialize(stream, employee1);
        stream.Close();

        IFormatter formatter1 = new BinaryFormatter();
        Stream stream1 = new FileStream("MyBinaryEmployee.dat", FileMode.Open, FileAccess.Read, FileShare.Read);
        EmployeeEntity obj;
        while(stream1.Position!=stream1.Length)
            obj = (EmployeeEntity)formatter1.Deserialize(stream1);
        
        stream1.Close();

其中EmployeeEntity的定义如下

EmployeeEntity
[Serializable]
    public class EmployeeEntity
    {
        Private Member#region Private Member

        private string employeeNumber;

        private string employmentStatus;

        private string nickname;

        private string lastName;

        private string firstName;

        private DateTime inputDateTime;

        #endregion



        Public Accessor#region Public Accessor

        public string EmployeeNumber
        {

            get { return employeeNumber; }

            set { employeeNumber = value; }

        }

        public string EmploymentStatus
        {

            get { return employmentStatus; }

            set { employmentStatus = value; }

        }

        public string Nickname
        {

            get { return nickname; }

            set { nickname = value; }

        }

        public string LastName
        {

            get { return lastName; }

            set { lastName = value; }

        }

        public string FirstName
        {

            get { return firstName; }

            set { firstName = value; }

        }

        public DateTime InputDateTime
        {

            get { return inputDateTime; }

            set { inputDateTime = value; }

        }

        #endregion



        Supplement methods#region Supplement methods

        public string Fullname
        {

            get { return firstName + " " + lastName; }

        }

        #endregion



        public EmployeeEntity()
        {

            //

            // TODO: Add constructor logic here

            //

        }
    }
