我有一个使用多个 ISubscribers 到 Redis 当其中一个使用 ISubscribers.UnsubscribeAsync/Unsubscribe/UnsubscribeAll/UnsubscribeAllAsync 所有其他的回调都不再触发。
有人知道为什么会这样吗？为了看它是不是从 Redis ，我正在使用 Redis-Cli 作为目标频道的订户 Redis-Cli 作为目标频道的发布者。
在我的代码中，我启动订户，在某个时候我使用 Unsubscribe 在此目标订户取消订阅后，所有其他回调将停止触发：

从左到右：
redis cli订阅服务器
控制台应用程序输出
redis cli发布服务器
如何繁殖

- subscribe K  ISubscribers to channel
- publish to channel and all ISubscribers callbacks trigger
- ISubscriber T unsubscribes from channel
- remaining ISubscribers stop having their callbacks called

代码

class Program {
        public static string CHANNEL = "chan";
        public static TaskCompletionSource<bool> tcs = new System.Threading.Tasks.TaskCompletionSource<bool>();
        public static TaskCompletionSource<bool> tcs2 = new TaskCompletionSource<bool>();
        public static int INITIAL_COUNT = 3;
        static async Task Main(string[] args) {
            List<ISubscriber> subs = new List<ISubscriber>();

            ConnectionMultiplexer mux = ConnectionMultiplexer.Connect("localhost:6379");
            for (int i = 0; i < INITIAL_COUNT; i++) {
                var sub = mux.GetSubscriber();
                int closuredIdentity = i;
                await sub.SubscribeAsync(CHANNEL, async (chan, msg) => {
                   if(msg=="k" && closuredIdentity == 0) {
                        Console.WriteLine($"Subscriber[{closuredIdentity}] unsubscribes");
                        await sub.UnsubscribeAsync(CHANNEL);
                        tcs.SetResult(true);
                    }
                    Console.WriteLine($"From sub[{closuredIdentity}]:{msg}");
                });
                subs.Add(sub);
            }
            var destroyerSubscriber = subs.FirstOrDefault();
            await tcs.Task;
            Console.WriteLine("Messages post unsubscribe");

            await destroyerSubscriber.SubscribeAsync(CHANNEL, async (chan, msg) => {
                if (msg == "k") {
                    tcs2.SetResult(true);
                }
            });
            await tcs2.Task;
            Console.WriteLine("Hello World!");
        }

    }

正如你从下面看到的，这似乎是一个 StackExchangeRedis 自从 Redis-Cli 订户即使在 .NET subscriber 取消订阅。所有其他 .NET subscribers 的回调停止触发。
