Serializing can be used to directly write the data properties of the Tutorial class to a file. Deserialization is used to read the data from the file and construct the Tutorial object again. This sample show serialize and deserialize by use binary format. 1. Import this 2 names space Imports System.Runtime.Serialization.Formatters.Binary Imports System.IO 2. The class or object that you want implement must insert attribute Serializable. <system.serializable() >Public Class Person Private m_sFirstName As String Private m_sLastName As String Public Sub New() End Sub Public Property FirstName() As String Get Return Me.m_sFirstName End Get Set(ByVal value As String) Me.m_sFirstName = value End Set End Property Public Property LastName() As String Get Return Me.m_sLastName End Get Set(ByVal value As String) Me.m_sLastName = value End Set End Property Public ReadOnly Property FullName() As String Get Return Me.m_sFirstName & "" "" & Me.m_sLastName End Get End Property End Class 3. Sample code show how to do this. ' Create object instance Dim pPerson As New Person() pPerson.FirstName = ""TOM"" pPerson.LastName = ""BROWN"" ' Create file by FileStream class Dim fs As FileStream = New FileStream(""c:\test.bin"", FileMode.OpenOrCreate) ' Creat binary object Dim bf As New BinaryFormatter() ' Serialize object to file bf.Serialize(fs, pPerson) fs.Close() ' Open file and deserialize to object again Dim fsRead As New FileStream(""C:\test.bin"", FileMode.Open) Dim objTest As Object = bf.Deserialize(fsRead) fsRead.Close()
