Public Function TryAddMessage (message As ServiceBusMessage) As Boolean



The message to attempt to add to the batch.


true if the message was added; otherwise, false.


When a batch is sent, it will be locked for the duration of that operation. During this time, no messages may be added to the batch. Calling TryAdd while the batch is being sent will result in an InvalidOperationException until the send has completed.

Occurs when the message has a member in its ApplicationProperties collection that is an unsupported type for serialization. See the ApplicationProperties remarks for details.


When a message is accepted into the batch, changes made to its properties will not be reflected in the batch nor will any state transitions be reflected to the original instance.

Note: Any ReadOnlyMemory<T>, byte array, or BinaryData instance associated with the event is referenced by the batch and must remain valid and unchanged until the batch is disposed.
