c# - 没有连接可用于服务此操作 : ZRANGEBYSCORE redis

Question

我总是收到这个错误

asp.net核心2.0

StackExchange.Redis.StrongName 1.2.6

3 redis server 1 master 2 replica

仅从副本读取并写入主副本

像这样初始化连接管理器

 public  static class X
    {
        static string connectionString;

        public static void InitializeConnectionString(string cnxString)
        {
            if (string.IsNullOrWhiteSpace(cnxString))
                throw new ArgumentNullException(nameof(cnxString));

            connectionString = cnxString;
        }

        private static readonly Lazy LazyConnection = new Lazy(() =>
        {
            var connection = ConnectionMultiplexer.Connect(connectionString);
            connection.PreserveAsyncOrder = false;
            return connection;

        });

        public static ConnectionMultiplexer SafeCoonect
        {
            get
            {
                return LazyConnection.Value;
            }
        }
      }
