问题描述

我收到了以下异常.它是随机发生的，但是会杀死我的WPF应用程序.大家知道原因是什么，也许是解决办法?

高兴，
Sonny

Hi,

I'm getting the following exception. It happens quite randomly but it kills my WPF application. Do you folks know what the cause and maybe the fix for this?

cheers,
Sonny

推荐答案

您好，Sonny Soriano，

没有任何代码，很难说出导致异常的原因.
您是否按索引访问数组条目?

Hi Sonny Soriano,

without any code its hard to say what cause the exception.

Do you access Array entries by index?
