Remarks

The body of a Message instance can only be accessed or written once. If you wish to access a Message instance more than once, you should use the MessageBuffer class to completely store an entire Message instance into memory.

A MessageBuffer instance is constructed by calling CreateBufferedCopy of a Message instance. A new MessageBuffer is then created and returned, which assumes ownership of the Message and reads the entire content into memory.

To retrieve a copy of a Message from the MessageBuffer, you must call the CreateMessage method of the MessageBuffer. This returns an identical copy of the original Message instance you provided.

You can control the maximum size of the buffer by setting BufferSize to the maximum number of bytes desired. This number does not necessarily cover any transient allocations related to building the buffer or properties attached to the message.

You should always close a MessageBuffer instance by calling Close when finished working with it. This ensures the underlying Message (the message passed into the constructor) instance is also closed, which frees system resources.
