序列化和反序列 asp.net c#

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/>");     } }
