ActiveXMessageFormatter Class

Serializes or deserializes primitive data types and other objects to or from the body of a Message Queuing message, using a format that is compatible with the MSMQ ActiveX Component.

Namespace: System.Messaging
Assembly: System.Messaging (in system.messaging.dll)

public class ActiveXMessageFormatter : IMessageFormatter, ICloneable
public class ActiveXMessageFormatter implements IMessageFormatter, ICloneable
public class ActiveXMessageFormatter implements IMessageFormatter, ICloneable
Not applicable.

The ActiveXMessageFormatter is compatible with messages sent using Message Queuing COM components, allowing interoperability with applications that use the MSMQ COM control.

The ActiveXMessageFormatter can serialize most primitives, as well as objects that implement the IPersistStream OLE interface. It can deserialize the same set of primitives, but requires further effort when deserializing a COM object (for example, an object created using Visual Basic 6.0) that implements IPersistStream. The object to deserialize must be in memory by first importing the object into a .NET Framework application.

When an application sends a message to the queue using an instance of the MessageQueue class, the formatter serializes the object into a stream and inserts it into the message body. When reading from a queue using a MessageQueue, the formatter deserializes the message data into the Body property of a Message.

ActiveX serialization is very compact, which makes using the ActiveXMessageFormatter and MSMQ COM control a very fast method of serialization.
