ObjectStateFormatter.Serialize Method (Stream, Object)

Serializes an object state graph to the specified Stream object.

Namespace:  System.Web.UI
Assembly:  System.Web (in System.Web.dll)

public void Serialize(
	Stream outputStream,
	Object stateGraph


Type: System.IO.Stream
A Stream to which the ObjectStateFormatter serializes the state of the specified object.
Type: System.Object
The object to serialize.


The specified inputStream is null.

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 override void Save()

    if (ViewState != null || ControlState != null)
        if (Page.Session != null)
            Stream stateStream = GetSecureStream();

            StreamWriter writer = new StreamWriter(stateStream);

            IStateFormatter formatter = this.StateFormatter;
            Pair statePair = new Pair(ViewState, ControlState);

            // Serialize the statePair object to a string.
            string serializedState = formatter.Serialize(statePair);

            throw new InvalidOperationException("Session needed for StreamPageStatePersister.");
