Public Function TryAdd (eventData As EventData) As Boolean
Parameters
- eventData
- EventData
The event to attempt to add to the batch.

Exceptions
When a batch is published, it will be locked for the duration of that operation. During this time,
no events may be added to the batch. Calling TryAdd
while the batch is being published will
result in an InvalidOperationException until publishing has completed.
Occurs when the eventData
has a member in its Properties collection that is an
unsupported type for serialization. See the Properties remarks for details.
Remarks
When an event 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.
