Deserializes the stream into an object graph with any headers in that stream being handled by the given System.Runtime.Remoting.Messaging.HeaderHandler.
The top object of the deserialized graph (root).
Headers are used only for specific remoting applications. The System.Runtime.Remoting.Messaging.HeaderHandler parameter is one of two ways to return headers from a stream in SOAP Remote Procedure Call (RPC) format. The other way is to use the SoapFormatter.TopObject property.
For successful deserialization, the current position in the stream must be at the beginning of the object graph.
TimeSpan objects are serialized according to the ISO 8601: 1998 section 5.5.3.2.1 "Alternative" standard.
