Deserializes a stream into an object graph.
Overload List
Deserializes the specified stream into an object graph.
[Visual Basic] Overloads Public Overridable Function Deserialize(Stream) As Object Implements IFormatter.Deserialize
[C#] public virtual object Deserialize(Stream);
[C++] public: virtual Object* Deserialize(Stream*);
[JScript] public function Deserialize(Stream) : Object;
Deserializes the specified stream into an object graph. The provided HeaderHandler handles any headers in that stream.
[Visual Basic] Overloads Public Overridable Function Deserialize(Stream, HeaderHandler) As Object Implements IRemotingFormatter.Deserialize
[C#] public virtual object Deserialize(Stream, HeaderHandler);
[C++] public: virtual Object* Deserialize(Stream*, HeaderHandler*);
[JScript] public function Deserialize(Stream, HeaderHandler) : Object;
Example
[Visual Basic, C#, C++] Note This example shows how to use one of the overloaded versions of Deserialize. For other examples that might be available, see the individual overload topics.
