搜了一下可以用 AggregateException 来集中抛出异常。

protected void OnMyEvent()
{
    EventHandler handler = MyEvent;
    if (handler != null)
    {
        List<Exception> exceptions = null;
        foreach (var d in handler.GetInvocationList())
        {
            try
            {
                ((EventHandler)d)(this, EventArgs.Empty);
            }
            catch (Exception exc)
            {
                if (exceptions == null)
                    exceptions = new List<Exception>();
                exceptions.Add(exc);
            }
        }

        if (exceptions != null)
            throw new AggregateException(exceptions);
    }
}

就应该用 AggregateException
