找不到類型或名稱空間名稱“ BasicAckEventHandler”（您是否缺少using指令或程序集引用？）

Question

我試圖在C＃中實現發布者確認，並嘗試在SO上找到以下代碼。

https://stackoverflow.com/a/18211367/3139595

_rabbitMqChannel.BasicAcks += new BasicAckEventHandler(_rabbitMqChannel_BasicAcks);
_rabbitMqChannel.BasicNacks += new BasicNackEventHandler(_rabbitMqChannel_BasicNacks);

_rabbitMqChannel.ExchangeDeclare(ExchangeName, ExchangeTypeVal.ToString());
_rabbitMqChannel.QueueDeclare(QueueName, QueueDurable, QueueExclusive, QueueDelete, null);
_rabbitMqChannel.QueueBind(QueueName, ExchangeName, RoutingKey);
and here is how the event handlers methods will look like...

private void _rabbitMqChannel_BasicNacks(IModel model, BasicNackEventArgs args)
{
    throw new NotImplementedException();
}

private void _rabbitMqChannel_BasicAcks(IModel model, BasicAckEventArgs args)
{
    throw new NotImplementedException();
}

這個答案似乎對他有用，但是我遇到了以下錯誤。

The type or namespace name 'BasicAckEventHandler' could not be found (are you missing a using directive or an assembly reference?) 

我正在使用Rabbitmqdotnet dll的當前版本：rabbitmq-dotnet-client-3.6.5-dotnet-4.5

難道他們也從最新版本中退出BasicAckEventHandler嗎？ 還是我在那里缺少任何東西？

注意：我有以下使用聲明

using RabbitMQ.Client;
using RabbitMQ.Client.Events;

在3.5.0中，RabbitMqdotNet家伙用EventHandler替換了BasicAckEventHandler類型，請參閱我最終如何編寫發布者。 感謝@Chris Dunaway的評論，這使我指向了此鏈接
