如何创建异常并将AggregateException作为内部异常传递?

想象一下这个场景:

Task.Run(() =>
    {
        // code...
    }).ContinueWith(x =>
    {
        var betterEx = new Exception("My custom message", x.Exception));
    }
    , TaskContinuationOptions.OnlyOnFaulted);

然而 betterEx.InnerException null .

new Exception 然后传球 AggregateException
