Any object state graph that is serialized with the Serialize method can be deserialized with the Deserialize method. The Serialize(Stream, Object) method is used to serialize an object state graph to a binary Stream object.
The following code example demonstrates how a class retrieves an ObjectStateFormatter instance to serialize view state and control state to a stream using the Serialize(Stream, Object) method. This code example is part of a larger example provided for the PageStatePersister class.
' ' Persist any ViewState and ControlState. ' Public Overrides Sub Save() If Not (ViewState Is Nothing) OrElse Not (ControlState Is Nothing) Then If Not (Page.Session Is Nothing) Then Dim stateStream As Stream stateStream = GetSecureStream() ' Write a state string, using the StateFormatter. Dim writer As New StreamWriter(stateStream) Dim formatter As IStateFormatter formatter = Me.StateFormatter Dim statePair As New Pair(ViewState, ControlState) Dim serializedState As String serializedState = formatter.Serialize(statePair) writer.Write(serializedState) writer.Close() stateStream.Close() Else Throw New InvalidOperationException("Session needed for StreamPageStatePersister.") End If End If End Sub 'Save
