Public Function UnsafeDeserialize (serializationStream As Stream, handler As HeaderHandler) As Object

Parameters

serializationStream: Stream

The stream from which to deserialize the object graph.

handler: HeaderHandler

The HeaderHandler that handles any headers in the serializationStream. Can be null.

Returns

Object

The deserialized object or the top object (root) of the object graph.

Attributes: ComVisibleAttribute SecurityCriticalAttribute

Exceptions

ArgumentNullException

The serializationStream is null.

SerializationException

The serializationStream supports seeking, but its length is 0.

Remarks

Warning

BinaryFormatter is insecure and can't be made secure. For more information, see the BinaryFormatter security guide.

Headers are used only for specific remoting applications.

For successful deserialization, the current position in the stream must be at the beginning of the object graph.

Important

Calling this method with untrusted data is a security risk. Call this method only with trusted data. For more information, see Validate All Inputs.
