George,
Short answer: You Don't!!!!
Long answer: You cannot deserialize a class to "me" as by the time the
constructor executes the object has already been created. Deserialization
creates a new object!
A couple of alternatives would be to add a Factory Method to your class that
deserializes an instance of the class and return it.
Public Class cJob
Private m_attr1 As String
Private m_attr2 As String
Public Shared Function FromFile(ByVal filename as string) As cJob
fs = New System.IO.FileStream(filename,
System.IO.FileMode.Open)
Dim sf As New
System.Runtime.Serialization.Formatters.Soap.SoapF ormatter
return DirectCast(sf.Deserialize(fs), cJob)
End
End Class
Note that the above Factory Method is a Shared method (you do not need an
instance of the class to use it) and it returns an instance of the class.
A more involved alternative is to have a class private to cJob that contains
all of cJOb's data, then each method of cJob would delegate to this private
class
Public Class Job
Private Class JobData
Private m_attr1 As String
Private m_attr2 As String
End Class
Private Readonly m_data As JobData
Public Sub New()
m_data = new JobData
End Sub
Public Sub New(ByVal filename as string) fs = New System.IO.FileStream(filename,
System.IO.FileMode.Open)
Dim sf As New
System.Runtime.Serialization.Formatters.Soap.SoapF ormatter
m_data = DirectCast(sf.Deserialize(fs), JobData)
End
End Class
Of course this runs into problems when you attempt to serialize, as you
cannot really serialize the Job object, you need to serialize the JobData
object. I would favor the Factory Method.
Hope this helps

news:10****************************@phx.gbl... I understand this might not be the optimal method of
deserialization, but how can I deserialize a class to
itself? Something like:
Public Sub New(Optional ByVal filename as string =
Nothing)
If Not IsNothing(filename) then
fs = New System.IO.FileStream(filename,
System.IO.FileMode.Open)
Dim sf As New
System.Runtime.Serialization.Formatters.Soap.SoapF ormatter
me = CType(sf.Deserialize(fs), cJob)
End If
End Sub
