c# - 如何在 Servicestack.Redis 中使用 "New Managed Pub/Sub Server"取消订阅 channel

Question

在New Managed Pub/Sub Server他们的文档展示了如何在 pubsubserver 的初始化中订阅 channel 。但是，您如何在程序稍后需要时取消订阅特定 channel ？

我的代码:

using ServiceStack.Redis;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading;

namespace va.communication
{
    class Program
    {
        static void Main(string[] args)
        {
            var clientsManager = new PooledRedisClientManager();

            //subscribe to channels 'messages' and 'queue'
            var redisPubSub = new RedisPubSubServer(clientsManager, "messages","queue")
            {
                OnUnSubscribe = (channel) =>
                {
                    Console.WriteLine("Unsubscribed from channel '{0}'", channel);
                },
                OnMessage = (channel, msg) =>
                {
                    Console.WriteLine("Received '{0}' from channel '{1}'", msg, channel);
                }
            };
            redisPubSub.Start();

            //...
            //other code which takes ~5s after which i want to unsubscribe from 'messages'
            Thread.Sleep(5000); 
            //...

            //no longer require channel 'messages'. what to do here?

            while (true) ;//continue with other code
        }
    }
}

调用 Stop() 或 Dispose() 将取消订阅并停止收听订阅的 channel 。如果您想稍后再次开始收听，请使用 Stop() ；如果您已完成 RedisPubSubManager，请使用 Dispose() 。
