如何使用反射将事件处理程序附加到事件?

EventInfo.AddEventHandler(...)

//场景当我的解决方案中有所有可用的东西时,零反射场景。

internal class SendCommentsManager
{
    public void Customize(IRFQWindowManager rfqWindowManager)
    {
        rfqWindowManager.SendComment += HandleRfqSendComment;
    }

    private void HandleRfqSendComment(object sender, SendCommentEventArgs args)
    {
        args.Cancel = true;
    }
}

AddEventHandler "Error binding to target method." 例外。

我理解此异常背后的原因,将错误的委托附加到事件。但一定有办法做到这一点。

 internal class SendCommentsManagerUsingReflection
 {
     public void Customize(IRFQWindowManager rfqWindowManager)
     {
         EventInfo eventInfo = rfqWindowManager.GetType().GetEvent("SendComment");
         eventInfo.AddEventHandler(rfqWindowManager, 
             Delegate.CreateDelegate(eventInfo.EventHandlerType, this, "HandleRfqSendComment"));
         //<<<<<<<<<<ABOVE LINE IS WHERE I AM GOING WRONG>>>>>>>>>>>>>>
     }

     private void HandleRfqSendComment(object sender, object args)
     {
         Type sendCommentArgsType = args.GetType();
         PropertyInfo cancelProperty = sendCommentArgsType.GetProperty("Cancel");
         cancelProperty.SetValue(args, true, null);
     }
 }
