订阅类别流，事件永远不会出现在订阅客户端

作为GetEventStore的第一次用户并阅读了文档，我遇到了一个问题，事件从未出现在我的订阅客户端上。订阅类别流，事件永远不会出现在订阅客户端

这可能是由于我错过了一个配置步骤。

有了这个控制台应用程序客户端：

public class EventStoreSubscriptionClient : ISubscriptionClient 
{ 
    private const string GroupName = "liner"; 
    private const string StreamName = "$ce-happening"; 

    private readonly IProvideEventStoreConnection _eventStoreConnection; 
    private readonly UserCredentials _userCredentials; 

    private EventStorePersistentSubscriptionBase EventStorePersistentSubscriptionBase { get; set; } 

    public EventStoreSubscriptionClient(IProvideEventStoreConnection eventStoreConnection, UserCredentials userCredentials) 
    { 
     _eventStoreConnection = eventStoreConnection; 
     _userCredentials = userCredentials; 
    } 

    public void Connect() 
    { 
     var connection = _eventStoreConnection.ConnectAsync().Result; 
     EventStorePersistentSubscriptionBase = connection.ConnectToPersistentSubscription(
       StreamName, 
       GroupName, 
       EventAppeared, 
       SubscriptionDropped, 
       _userCredentials, 
       10, 
       false 
     ); 
    } 

    private void SubscriptionDropped(EventStorePersistentSubscriptionBase subscription, SubscriptionDropReason reason, Exception ex) 
    { 
     Connect(); 
    } 

    private async void EventAppeared(EventStorePersistentSubscriptionBase subscription, ResolvedEvent resolvedEvent) 
    { 
     Console.WriteLine("Event appeared: " + resolvedEvent.Event.EventId); 
    } 

    public void Dispose() 
    { 
     EventStorePersistentSubscriptionBase.Stop(TimeSpan.FromSeconds(15)); 
    } 
}

一旦启动这个控制台应用程序，连接云罚款http://myserver:1113。在我的事件商店，我能看到的管理面板有竞争消费者标签此流/组的连接：
