Question

我是Akka.NET的新手。我最近开始做我的大学项目并遇到了一个奇怪的问题。我在两个不同的桌面应用程序中有两个ActorSystems。在第一个ActorSystem中，我使用Akka.Remote在两个actor之间发送消息ZippedAddressListMessage。

public class ZippedAddressListMessage
    {
        public ZippedAddressListMessage(List<string> list)
        {
            this.Values = list.AsReadOnly();
        }

        public IReadOnlyCollection<string> Values { get; private set; }

    }

这很好用，但是当我尝试将此消息发送到其他ActorSystem时，我得到了大量的错误： screenshot #1 of the console window with the error

然而，如果我发送一个只包含一个整数的简单消息，那么一切都很好。可能存在序列化问题，但我无法弄清楚它是如何解决的。我到处搜索，但仍未找到答案。拜托，您能解释一下如何解决这个问题吗？

}

}

更新： 这里是开头错误的屏幕截图。 screenshot #2 of the console window with the error 它写道，System.String []的格式与JSON序列化不兼容。

Answer 1

问题解决了！问题是关于序列化器：我使用的是Newtonsoft.Json序列化器。在向远程ActorSystem发送消息时，它不能序列化列表。 Newtonsoft解释说System.String []是不兼容的类型。

解决方案是安装Hyperion序列化程序： http://getakka.net/docs/Serialization#how-to-setup-wire-as-default-serializer
