In this article we are going to see how to serialize and deserialize an object as binary data using the binary formatter.
Step 1: Used Namespace
using System; using System.Collections; using System.IO; using System.Runtime.Serialization.Formatters.Binary;
Step 2: Usage
protected void Page_Load(object sender, EventArgs e) { Employees emps = new Employees();
emps.Add(new Employee("1", "Lajapathy")); emps.Add(new Employee("2", "Anand"));
emps.Add(new Employee("3", "Sathiya")); emps.Add(new Employee("4", "Lakshmi")); emps.Add(new Employee("5", "Parthiban")); string pth = @"D:Test.bin"; //Serializing the collection Serialize(emps, pth); //Deserializing the collection Deserialize(pth); }
Step 3: Serializing the Object using Binary Formatter
//Serializing the List public void Serialize(Employees emps, String filename) { //Create the stream to add object into it. System.IO.Stream ms = File.OpenWrite(filename); //Format the object as Binary
BinaryFormatter formatter = new BinaryFormatter(); //It serialize the employee object formatter.Serialize(ms, emps); ms.Flush(); ms.Close(); ms.Dispose(); }
Step 4: Deserializing the Object using Binary Formatter
//Deserializing the List public void Deserialize(String filename) { //Format the object as Binary BinaryFormatter formatter = new BinaryFormatter(); //Reading the file from the server FileStream fs = File.Open(filename, FileMode.Open); object obj = formatter.Deserialize(fs); Employees emps = (Employees)obj; fs.Flush(); fs.Close(); fs.Dispose(); foreach (Employee employee in emps) { Response.Write(employee.Name + "<br/>"); } }
Step 5: Output Path of Serialization:
Step 6: Output of Deserialization:
//Deserializing the List public void Deserialize(String filename) { //Format the object as Binary BinaryFormatter formatter = new BinaryFormatter(); //Reading the file from the server FileStream fs = File.Open(filename, FileMode.Open); object obj = formatter.Deserialize(fs); Employees emps = (Employees)obj; fs.Flush(); fs.Close(); fs.Dispose(); foreach (Employee employee in emps) { Response.Write(employee.Name + "<br/>"); } }
