c# - RunAsync中的生成角色抛出“对象'CustomActorService.InternalCustomActorService'未实现接口(interface)ID'1830616258'”

我遵循Service Fabric spawn actor on startup中的建议在服务启动时生成几个参与者。我有一个自定义ActorService子类，具有以下RunAsync重写：

internal sealed class InternalCustomActorService : ActorService
{
  protected async override Task RunAsync(CancellationToken cancellationToken)
  {
    await base.RunAsync(cancellationToken);

    for(int i = 0; i < 10; i++)
    {
      ICustomActor proxy = ActorProxy.Create<ICustomActor>(new ActorId(i));
      await proxy.StartAsync();
    }
  }
...

该类在program.cs中注册如下：

    ActorRuntime.RegisterActorAsync<CustomActor>(
       (context, actorType) => new InternalCustomActorService(context, actorType, () => new CustomActor())).GetAwaiter().GetResult();

但是，调用proxy.StartAsync()方法时出现以下异常：

FatalExecutionEngineError occurred

  Message=One or more errors occurred.

我的问题是：我做错了什么？
编辑：我试图添加额外的BootstrapperService无状态服务，并在BootstrapperService.RunAsync中从那里生成参与者：

protected override async Task RunAsync(CancellationToken cancellationToken)
{
  await base.RunAsync(cancellationToken);
  await Task.Delay(10000);

  for (int i = 0; i < 10; i++)
  {
    ICustomActor proxy = ActorProxy.Create<ICustomActor>(new ActorId(i));
    await proxy.StartAsync();
  }
}

尽管如此，调用proxy.StartAsync()抛出的异常与上面的InternalCustomActorService.RunAsync中的异常完全相同。

最佳答案

从自定义参与者服务中删除以下代码：

     protected override IEnumerable<ServiceReplicaListener> CreateServiceReplicaListeners()
 {
   var remotingListener = new ServiceReplicaListener(context => this.CreateServiceRemotingListener(context));
   return new ServiceReplicaListener[] { remotingListener };
 }

这将删除基本ActorService正在设置的ActorRemotingListener。如果要添加其他侦听器，请调用基本createservicereplicalisteners方法，获取侦听器，然后添加自定义侦听器。
