.NET Exceptions (all of them)
July 8, 2009 § 19 Comments
I wanted a list of .NET exceptions. I went looking and couldn’t really find what I was looking for. This post on codinghorror.com helped me get started (especially the work Paul Cotter did), but didn’t really answer the whole question for me. I hacked up the source code that was posted on the site, referenced the XML file generated from the XML comments in the .NET assemblies, linked the exceptions to the MSDN documentation, and generated the following list.
Some of these links are broken (they don’t seem to be documented exceptions). I will probably update this post at some point to remove the links for the exceptions that aren’t documented. I will also post the source code I used to generate the list once all the embarrassing hacks are cleaned up. Check back in a day or two. You can find the source code here.
This list is based on the 3.5 framework.

currently im working with wcf, client requires that all exception messages are delivered in spanish (servers are in english) so i need a list of all possible exceptions (or most of them) to implement a translation class, any ideas? any one knows where i can get the description of all system.servicemodel namespace exceptions? btw , great code , thanx
i found the fr 3.0 and 3.5 xml comment files at
C:\Program Files\Reference Assemblies\Microsoft\Framework\v3.5
and

this is where the vs object browser querys the data.

It has covered all Exceptions i needed with good explanation,Thank you.
Nice one, page bookmarked. I’ll be grabbing the source too, in case your blog goes away ever 😉
kewl!
I am so grateful to you for putting this together. This is exactly what I need.
Thanks

The XML generated was not strictly legal – missing a couple of end tags. There is probably a more elegant fix, but the quick and dirty was to add:
Console.WriteLine(“”); // before main loop
Console.WriteLine(“”); // before “”
Console.WriteLine(“”); // after main loop
But a great program anyway! Thanks.
Oops, the XML tags got stripped from my previous comment. Here they are with angle brackets replaced by square brackets:
Write [ExceptionList] before main loop
Write [/namespace] before writing [/module]
Write [/ExceptionList] after main loop
I love what you guys are up too. This kind of clever work
and reporting! Keep up the amazing works guys I’ve added you guys to our blogroll.
