Schedules a set of messages to appear on Service Bus at a later time.
public virtual System.Threading.Tasks.Task<System.Collections.Generic.IReadOnlyList<long>> ScheduleMessagesAsync(System.Collections.Generic.IEnumerable<Azure.Messaging.ServiceBus.ServiceBusMessage> messages, DateTimeOffset scheduledEnqueueTime, System.Threading.CancellationToken cancellationToken = default);abstract member ScheduleMessagesAsync : seq<Azure.Messaging.ServiceBus.ServiceBusMessage> * DateTimeOffset * System.Threading.CancellationToken -> System.Threading.Tasks.Task<System.Collections.Generic.IReadOnlyList<int64>>
override this.ScheduleMessagesAsync : seq<Azure.Messaging.ServiceBus.ServiceBusMessage> * DateTimeOffset * System.Threading.CancellationToken -> System.Threading.Tasks.Task<System.Collections.Generic.IReadOnlyList<int64>>Public Overridable Function ScheduleMessagesAsync (messages As IEnumerable(Of ServiceBusMessage), scheduledEnqueueTime As DateTimeOffset, Optional cancellationToken As CancellationToken = Nothing) As Task(Of IReadOnlyList(Of Long))Parameters
- messages
- IEnumerable<ServiceBusMessage>
The set of messages to schedule.
- scheduledEnqueueTime
- DateTimeOffset
The UTC time at which the message should be available for processing
- cancellationToken
- CancellationToken
An optional CancellationToken instance to signal the request to cancel the operation.
Returns
The sequence number of the message that was scheduled.
Exceptions
Occurs when one of the messages has a member in its ApplicationProperties collection that is an
unsupported type for serialization. See the ApplicationProperties remarks for details.
Remarks
Although the message will not be available to be received until the scheduledEnqueueTime, it can still be peeked before that time. Messages can also be scheduled by setting ScheduledEnqueueTime and using SendMessageAsync(ServiceBusMessage, CancellationToken), SendMessagesAsync(IEnumerable<ServiceBusMessage>, CancellationToken), or SendMessagesAsync(ServiceBusMessageBatch, CancellationToken).
When scheduling, the result is atomic; either all messages that belong to the set were successful or all have failed. Partial success is not possible.
