一个委托的多个事件

注意；正在发布伪代码示例。。。请参阅下面的示例文本(我告诉过你这将是一个滑稽的混乱！(

Class Enter
{
  public event EnterDelegate EnterDelegateEvent;
  public event ExitDelegate ExitDelegateEvent;
  public Enter(EventEventArgs e)
  {
     // do something
     EnterOrder(e);
     ExitEventArgs ev = new ExitEventArgs(string ticker, double prices.. etc);
     ExitEvent(ev);
      // update order status etc.
  }
  private double EnterOrder()
  {
     double ent = 0.00
     if (EnterDelegateEvent != null)
     {
         ent = EnterDelegateEvent(this, e);
         return ent;
     }
     else { return e.lo;  }
  }
   public double ExitEvent(ExitEventArgs e)
   {
     // do something
     ExitEvent(ev);
   }
   private double ExitEvent()
   {
     double ext = 0.00
     if (ExitDelegateEvent != null)
     {
         ext = ExitDelegateEvent(this, e);
         return ext;
     }
     else { return e.Hi;  }
   }
}  // end Enter Class

Class EventHandlers
{
   public double SendEnter(EventArgs e)
   {
       // send enter to order server here
       return price;
   }
   public double SendExit(EventArgs e)
   {
       // send exit to order server here
       return price
   }
}

Orders Class
{
   Enter ent = new Enter();
   public GetOrders()
   {
      // get order data
      // create order event
      EnterEventArgs ev = new EnterEventArgs(ticker, price, data...etc);
      ent.Enter(ev);
    }
}
Orders.aspx.cs
{
    EventHandlers evt = new EventHandlers();
    Enter ent = new Enter();
    Orders ord = new Orders();
    Private void login()
    {
       // log into Orders Server
       ent.EnterDelegateEvent += EnterDelegate(evt.SendEnter);
       ent.ExitDelegateEvent += ExitDelegate(evt.SendExit);
    }
    private void logout()
    {
        // delete / remove delegate event handlers;
    }
    // initiate orders example event
    private void btnclick_GetOrders()
    {
       ord.GetOrders();
    }
}

除了运行上面的GetOrders，我还需要从GetBackTest((运行另一组订单。。这有时需要同时进行，因此当它运行EnterOrder((例程时，EventDelegate需要返回if(EventDelegate==null(｛return e.price；｝

不是使用EventHandler方法。。。

Class Backtest
{
    Enter ent = new Enter();
   // kickoff enter order just as Orders Class does
    // this class needs to NOT use the Event Delegate as Orders class does
}

有没有一种简单的方法可以打开和关闭DelegateEvents，并确保只实例化其中一个？？如果我将Delegate事件设置为Static，那么backtest类将使用eventhandler方法。
