私有字段未发生二进制序列化 [英] Binary Serialization not happening for Private field

问题描述

我假设在二进制序列化中，我们可以序列化任何成员，无论它们是私有的，公共的，内部的还是受保护的，我知道的唯一条件是它应该具有默认的构造函数，以便进行序列化和反序列化.但是，在下面的示例中，我们无法对私人领域的工资进行服务

Hi I am assuming in Binary Serialization we can serialize any members irrespective of whether they are private or public or internal or protected, the only condition I am aware is that it should have a default constructor in order serialize and de-serialize. However in my below example we are not able to seriliaze private field salary

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Runtime.Serialization;
using System.Runtime.Serialization.Formatters.Binary;
using System.IO;
namespace BinarySerilization
{
    [Serializable]
    class Employee
    {

        public int Empid { get; set; }
        public String Empname { get; set; }
        public String Emplocation { get; set; }
        private int Empsalary;

        public int EmpSalary { get; set; }

    }



    class Program
    {
        static void Main(string[] args)
        {

            Employee emp = new Employee(); { emp.Empid = 101; emp.Empname = "xyz"; emp.Emplocation = "Bangalore"; emp.Empsalary = 50000; };
            IFormatter formattter = new BinaryFormatter();
            Stream str = new FileStream(@"C:\Users\XXXX_XX\Documents\Testing\new.txt", FileMode.Open, FileAccess.Write);
            formattter.Serialize(str, emp);
            str.Close();


            ////De-Serlization
            //IFormatter formatter = new BinaryFormatter();
            //Stream str = new FileStream(@"C:\Users\XXXX_XX\Documents\Testing\new.txt", FileMode.Open, FileAccess.Read);
            //Employee emp = formatter.Deserialize(str) as Employee;
            //Console.WriteLine(emp.Empid+"\t"+emp.Empname+"\t"+emp.Emplocation+"\t"+emp.Empsalary);

        }
    }
}

推荐答案

Class Employee根本不访问后备字段-

Class Employee doesn''t access the backing field at all -

class Employee
{

    public int Empid { get; set; }
    public String Empname { get; set; }
    public String Emplocation { get; set; }
    private int Empsalary;

    //This has no ties to the private field - the compiler will generate a (separate) backing field for it
    //public int EmpSalary { get; set; } 

   //This actually uses the backing field 
   public int EmpSalary 
   { 
      get {return Empsalary; }
      set { Empsalary = value;}
   } 
}

OT:同样，它调用字段Empsalary会造成混淆，尤其是对于首字母大写.我个人会使用_empSalary，尽管很多人会建议empSalary

OT: Also it calling the field Empsalary is confusing, especially with the lead capital. Personally I''d use _empSalary, though many people would suggest empSalary
