How-To read events from an Event Hub partition

To read from a specific partition, the consumer will also need to specify where in the event stream to begin receiving events : azure-sdk-for-net/README.md at main · Azure/azure-sdk-for-net · GitHub

var connectionString = "<< CONNECTION STRING FOR THE EVENT HUBS NAMESPACE >>";
var eventHubName = "<< NAME OF THE EVENT HUB >>";

string consumerGroup = EventHubConsumerClient.DefaultConsumerGroupName;

await using (var consumer = new EventHubConsumerClient(consumerGroup, connectionString, 
                                      eventHubName))
{
    EventPosition startingPosition = EventPosition.Earliest;
    string partitionId = (await consumer.GetPartitionIdsAsync()).First();

    using var cancellationSource = new CancellationTokenSource();
    cancellationSource.CancelAfter(TimeSpan.FromSeconds(45));

    await foreach (PartitionEvent receivedEvent 
        in consumer.ReadEventsFromPartitionAsync(partitionId, startingPosition, 
                                    cancellationSource.Token))
    {
       //...
    }
}
