serialization

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);

        }
    }
}
