在不使用 while 循环的情况下找到最内部的异常? [英] Find the inner-most exception without using a while loop?

问题描述

当 C# 抛出异常时，它可以有一个内部异常.我想要做的是获取最内部的异常，或者换句话说，没有内部异常的叶异常.我可以在 while 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;
}

但我想知道是否有一些单线可以用来代替.

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，你不能让它变得更简单.

Obviously, you can't make it any simpler.

正如 Glenn McElhoe 在 这个答案 中所说，这是唯一可靠的方法.

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