How to get topics list from Kafka using C#

Question

I want to get topics list from Kafka. I'm using kafka-net client but unable to find in documentation about fetching topics list.

Answer 1

You can list all topics using the AdminClient available in Confluent.Kafka package:

using Confluent.Kafka;
using Confluent.Kafka.Admin;

var adminConfig = new AdminClientConfig()
{
   BootstrapServers = "SERVER_URL"
};

using (var adminClient = new AdminClientBuilder(adminConfig).Build())
{
   var metadata = adminClient.GetMetadata(TimeSpan.FromSeconds(10));
   var topicsMetadata = metadata.Topics;
   var topicNames = metadata.Topics.Select(a => a.Topic).ToList();
}
