Applies to
Receive(Int32)
Receives Event Hubs event data, up to the specified count.
public System.Collections.Generic.IEnumerable<Microsoft.ServiceBus.Messaging.EventData> Receive (int maxCount);member this.Receive : int -> seq<Microsoft.ServiceBus.Messaging.EventData>Public Function Receive (maxCount As Integer) As IEnumerable(Of EventData)Parameters
- maxCount
- Int32
The maximum amount of event data the user is willing to accept in one call.
Returns
Returns the received
EventData collection. The collection is either empty if no event is returned within the specified time, or all events up to maxCount are returned.
Exceptions
Thrown if the service encounters a transient error.
Thrown if the client has a problem connecting to the service.
Thrown if the current namespace is placing too much load on the system.
Thrown if another receiver with a higher Epoch value is connected as the current receiver to the same partition specified by PartitionId.
Remarks
Service does not wait for maxCount events to be filled before returning to user. It returns as soon as there are any events available.
Applies to
Receive(TimeSpan)
Receives Event Hubs event data with the specified timeout value.
public Microsoft.ServiceBus.Messaging.EventData Receive (TimeSpan waitTime);member this.Receive : TimeSpan -> Microsoft.ServiceBus.Messaging.EventDataPublic Function Receive (waitTime As TimeSpan) As EventDataParameters
- waitTime
- TimeSpan
