This is what I try to achieve:
*serialize a class to a binary file
*get a BindingList(of class) or List(of class) from the binary file
*display the list in a DataGridView
I get InvalidCastException when I try to get info from the file.
My class:
Imports System.ComponentModel
Imports System.IO
Imports System.Runtime.Serialization
Imports System.Runtime.Serialization.Formatters.Binary
Imports System.Net.Mail
<Serializable()>
Public Class Server
Private _nume As String
Private _adresa As String
Private _port As String
Private _encryption As String
Private _username As String
Private _password As String
Public Property Nume As String
Get
Return _nume
End Get
Set(ByVal value As String)
_nume = value
End Set
End Property
Public Property Adresa As String
Get
Return _adresa
End Get
Set(ByVal value As String)
_adresa = value
End Set
End Property
Public Property Port As String
Get
Return _port
End Get
Set(ByVal value As String)
_port = value
End Set
End Property
Public Property Encryption As String
Get
Return _encryption
End Get
Set(ByVal value As String)
_encryption = value
End Set
End Property
Public Property Username As String
Get
Return _username
End Get
Set(ByVal value As String)
_username = value
End Set
End Property
Public Property Password As String
Get
Return _password
End Get
Set(ByVal value As String)
_password = value
End Set
End Property
Public Sub New()
End Sub
Public Sub New(ByVal nume As String, ByVal adresa As String, ByVal port As String, _
ByVal encryption As String, ByVal username As String, ByVal password As String)
_nume = nume
_adresa = adresa
_port = port
_encryption = encryption
_username = username
_password = password
End Sub
End Class
How I serialize:
*declare an object of class and apped values to eacy member then serialize it
How I deserialize:
ex:
Dim list as new BindingList(Of myclass)
'go to file, open it
list = formatter.Deserialize(filestream) 'and this is the line where it gives me the exception
