我有两个接口（一个用于订阅者，一个用于发布者）：

第一个应该对允许引发事件的客户端可见

   public interface IClientLogicEvents
   {
      IRaiseEvent<CallStateChangedEventArgs> CallStateChanged { get; }
   }

第二个应该对订阅和处理这些事件的客户端可见

   public interface IHandleOnlyClientLogicEvents : IClientLogicEvents
   {
      ISubscribeEvent<CallStateChangedEventArgs> CallStateChanged { get; }
   }

事件界面看起来像这样

   public interface ISubscribeEvent<out TEventArgs> where TEventArgs : EventArgs
   {
      void Subscribe(Action<object, TEventArgs> handler);
      void Unsubscribe(Action<object, TEventArgs> handler);
   }

    public interface IRaiseEvent<TEventArgs> : ISubscribeEvent<TEventArgs> where TEventArgs : EventArgs
   {
      void Raise(object sender, TEventArgs args);
   }

现在我想要一个实现这两个接口（IClientLogicEvents 和 IHandleOnlyClientLogicEvents）的类。

像这样：

public sealed class ClientLogicEvents : IClientLogicEvents, IHandleOnlyClientLogicEvents

或者：

 public sealed class ClientLogicEvents : IHandleOnlyClientLogicEvents

现在的问题当然是我需要实现该属性两次（对于每个接口），这需要一个额外的字段来存储它。

    public sealed class ClientLogicEvents : IClientLogicEvents, IHandleOnlyClientLogicEvents, IDisposable
   {
      /// <summary>
      /// The internal call state changed event.
      /// </summary>
      private readonly CustomEvent<CallStateChangedEventArgs> _callStateChangedEvent;

      public ClientLogicEvents()
      {
         _callStateChangedEvent = new CustomEvent<CallStateChangedEventArgs>();
      }

      /// <summary>
      /// Gets the invokeable call state changed event.
      /// </summary>
      IRaiseEvent<CallStateChangedEventArgs> IClientLogicEvents.CallStateChanged { get { return _callStateChangedEvent; } }

      /// <summary>
      /// Gets the subscribe only call state changed event.
      /// </summary>
      ISubscribeEvent<CallStateChangedEventArgs> IHandleOnlyClientLogicEvents.CallStateChanged { get { return _callStateChangedEvent; } }
   }

但我想为属性实现保存这么多代码（因为我有 200 个事件）。这是否可能以某种方式。我有类似的东西

    public sealed class ClientLogicEvents : IClientLogicEvents, IHandleOnlyClientLogicEvents, IDisposable
   {
      /// <summary>
      /// Gets the invokeable call state changed event.
      /// </summary>
      public IRaiseEvent<CallStateChangedEventArgs> CallStateChanged { get; private set; }
   }

?

您不能拥有一个满足来自两个接口的约束的属性，因为单个属性不能同时具有两种类型（IRaiseEvent<CallStateChangedEventArgs>和ISubscribeEvent<CallStateChangedEventArgs>）。

您在问题底部的示例未实现IHandleOnlyClientLogicEvents接口。
