This is my first article and I hope it helps you all. In this article I am going to show you how you can use xml serialization and deserialization in vb.net using xmlserializer and streamreader/writer.

Let's go ahead...

Open a new solution in vb.net, a windows application...

Put two buttons onto your form. Then open up your code view and write these codes. I am going to explain them...

Imports System.Xml.Serialization

Imports System.IO

Public Class Form1

 

 

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

 

 

        Dim srcustomer As New XmlSerializer(GetType(customer))

        Dim cust As New customer("Ibrahim""Ersoy""Programmer")

        Dim writestream As New StreamWriter("sampledb.xml")

        srcustomer.Serialize(writestream, cust)

 

    End Sub

 

    Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click

 

        Dim deser As New XmlSerializer(GetType(customer))

        Dim streamrd As New StreamReader("sampledb.xml")

        Dim cust1 As customer

        cust1 = deser.Deserialize(streamrd)

        MessageBox.Show(cust1.name & " " & cust1.surname & " is a " & cust1.jobtitle & ".""Deserialization")

 

    End Sub

 

End Class

 

Public Class customer

 

    Public name As String

    Public surname As String

    Public jobtitle As String

 

    Public Sub New()

    End Sub

 

    Public Sub New(ByVal name As StringByVal surname As StringByVal jobtitle As String)

        Me.name = name

        Me.surname = surname

        Me.jobtitle = jobtitle

    End Sub

 

End Class

 

First I am going to explain the first button's  job...

Dim srcustomer As New XmlSerializer(GetType(customer)): As you know we have created a class named customer. This means we create a xmlserializer in which we will be able to use our customer class...

Dim cust As New customer("Ibrahim""Ersoy""Programmer"):  This means we are going add our customer class new data, as we have declared on customer class like customer(Byval name as string... ) bla...bla...

Dim writestream As New StreamWriter("sampledb.xml"): In this code we are creating a xml-file named "sampledb.xml".

srcustomer.Serialize(writestream, cust): In here we are serializing, this means we are adding the datas to our xml-sampledb.

The second button's job:

Dim deser As New XmlSerializer(GetType(customer)): As you know we have created a class named customer. This means we create a xmlserializer in which we will be able to use our customer class...(as same as it is in the first button)

Dim streamrd As New StreamReader("sampledb.xml"):  In this code we are reading our sampledb.xml file...

cust1 = deser.Deserialize(streamrd: In this code we are deserializing so that we will be able to use them with a messagebox.

MessageBox.Show(cust1.name & " " & cust1.surname & " is a " & cust1.jobtitle & ".""Deserialization"):  Here is the Message that shows

Thats all...Imagine Serialization as creating a Xml file, and deserialization as reading the Xml-File...

If u have a problem, pls ask...
