C# .NET Exception stack hierachy

Posted in Uncategorized on July 23rd, 2009 by ph-lee – Be the first to comment

After getting to know ruby’s exceptions I decided to revisit them in C# .NET. Ruby has a small set of exceptions which developers can use in comparison to .NET framework which has many more. Although I do like the MSDN Library, I couldn’t find a quick and easy way of seeing an overview of all the exceptions built in the framework for browsing. After being inspired by [Sieger] in his Ruby’s Exception Hierarchy article I’d thought I do the same for C# .NET, and here’s the result…

By seeing the hierachy in full it should help developers manage their exceptions, expecially when trying to manage deep call stacks and ensuring they are handled in the correct order, helping to pin-point errors more precisely.

I’ve posted the source code used to generate the above output over at github.

Hope this has helped.
