IStateFormatter.Serialize Method (Object)
.NET Framework (current version)
Serializes ASP.NET Web server control state to string form.
Assembly: System.Web (in System.Web.dll)
Parameters
- state
-
Type:
System.Object
The object that represents the view state of the Web server control to serialize to string form.
Use the Serialize method to transform an object state graph to string form. Reconstitute a state object from the string using the Deserialize method.
The following code example demonstrates how the Serialize method persists view state information to a file. The Save method of the StreamPageStatePersister class uses the IStateFormatter interface inherited from the PageStatePersister class to serialize view state. This code example is part of a larger example provided for the IStateFormatter interface.
' ' 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
