OfficeSession Class

public sealed class OfficeSession : IDisposable

Public NotInheritable Class OfficeSession
	Implements IDisposable

// By default, the office decoder will create a new session for each document decoded.
// This leads to performance degradation if the same decoder is used to decode several files.
// To remedy this, the OfficeSession class was created, which encapulates a set of running Office
// applications, leaving them open for as long as they are needed.
// The session implements IDisposable, and must be disposed or have the Close method called when it is no longer needed.

    // With the OfficeDecoder created using the session, we now decode images as usual.
    // The decoder will now use the Office applications provided by the OfficeSession.
