找到最大的异常，而不使用while循环？ [英] Find the inner-most exception without using a while loop?

问题描述

当C＃抛出异常时，它可能有一个内部异常。我想要做的是获得最内在的异常，也就是说，没有内部异常的叶子异常。我可以在一段时间循环中执行此操作：

When C# throws an exception, it can have an inner exception. What I want to do is get the inner-most exception, or in other words, the leaf exception that doesn't have an inner exception. I can do this in a while loop:

while (e.InnerException != null)
{
    e = e.InnerException;
}

但是我想知道是否有一个单行我可以使用

But I was wondering if there was some one-liner I could use to do this instead.

推荐答案

Oneliner：）

Oneliner :)

while (e.InnerException != null) e = e.InnerException;

显然，你不能使它更简单。

Obviously, you can't make it any simpler.

正如Glenn McElhoe的这个答案所述，这是唯一可靠的方式。

As said in this answer by Glenn McElhoe, it's the only reliable way.
