如何在Confluent.Kafka中获得一个主题的所有‘`PartitionTopic`s’的列表？

using Confluent.Kafka;
using System;

class Program
{
    static void Main(string[] args)
    {
        string bootstrapServers = "your-bootstrap-servers"; // Kafka服务器地址

        // 配置Kafka生产者的参数
        var config = new ProducerConfig
        {
            BootstrapServers = bootstrapServers,
            ClientId = "my-client-id"
        };

        using (var producer = new ProducerBuilder<Null, string>(config).Build())
        {
            string topicName = "your-topic-name"; // 目标主题名称

            // 获取主题的元数据信息
            Metadata metadata = producer.GetMetadata(true);

            // 遍历主题列表，找到目标主题
            foreach (var topic in metadata.Topics)
            {
                if (topic.Topic.Equals(topicName))
                {
                    // 获取目标主题的所有分区
                    foreach (var partition in topic.Partitions)
                    {
                        Console.WriteLine($"Partition Id: {partition.PartitionId}");
                        Console.WriteLine($"Leader: {partition.Leader}");
                        Console.WriteLine($"Replicas: {string.Join(",", partition.Replicas)}");
                        Console.WriteLine($"In Sync Replicas: {string.Join(",", partition.InSyncReplicas)}");
                        Console.WriteLine($"Offline Replicas: {string.Join(",", partition.OfflineReplicas)}");
                        Console.WriteLine();
                    }

                    break; // 找到目标主题后退出循环
                }
            }
        }
    }
}
