Finding out what exceptions a method might throw in C#
提问by Helephant
Is there any way to find out what exceptions might be thrown by any method in .NET code? Ideally I want to see what might be thrown and choose which ones I want to handle. I guess I want the information you'd get from the throws clause in java.
有什么方法可以找出 .NET 代码中的任何方法可能抛出哪些异常？理想情况下，我想看看可能会抛出什么并选择我想要处理的那些。我想我想要你从 java 中的 throws 子句中得到的信息。
The situation is I'm doing a linq query on an xml document from the network and want to know what could go wrong. I could open up the assembly in reflector and have a look but I thought there might be an easier way.
情况是我正在对来自网络的 xml 文档进行 linq 查询，想知道可能会出现什么问题。我可以在反射器中打开组件并查看一下，但我认为可能有更简单的方法。

.NET does not have enforced ("checked") exceptions like java. The intellisense mightshow this information, if the developer has added a /// <exception.../>block - but ultimately more exceptions can happen than you expect (OutOfMemoryException, ThreadAbortException, TypeLoadException, etc can all happen fairly unpredictably).
.NET 没有像 java 这样的强制（“检查”）异常。如果开发人员添加了一个块，intellisense可能会显示此信息/// <exception.../>- 但最终可能会发生比您预期更多的异常（OutOfMemoryException、ThreadAbortException、TypeLoadException等都可能相当不可预测地发生）。
In general, you should have an idea of what things are likely to go wrong, and which ones you can actually do something useful about. In most cases, the correct behaviour is to let the exception bubble up (just running any "finally" code to release resources).
一般来说，您应该了解哪些事情可能会出错，哪些事情您实际上可以做一些有用的事情。在大多数情况下，正确的行为是让异常冒泡（只需运行任何“finally”代码来释放资源）。

As long as you're using BCL classes, they are all completely documented and Intellisense therefore displays any exception a method can throw. Other than that (and reading the docs), there is no way, I think.
只要您使用 BCL 类，它们都会被完整记录下来，因此 Intellisense 会显示方法可能抛出的任何异常。除此之外（和阅读文档），我认为没有办法。

I think that Exception huntercan provide this information however it costs money...
我认为异常猎人可以提供这些信息，但它需要花钱......

After reading another article about this on StackOverflow, I built on top of that other answer to write a tool to do this, you can get the source code from GitHub here:
