找到最内的异常而不使用而循环？ [英] Find the inner-most exception without using a while loop?

问题描述

在C＃中抛出一个异常，它可以有一个内部异常。我想要做的就是最内的异常，或换句话说，将叶片异常，不具有内异常。我可以在while循环做到这一点：

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;
}

不过，我想知道，如果有一些单行我可以用做这不是

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;

很显然，你不能让它再简单不过。

Obviously, you can't make it any simpler.

如格伦McElhoe这个答案说，这是唯一可靠的方法。

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