In our solution we have a project that contains all the exceptions.
All of the exceptions inherit our base exception which inherits from ApplicationException.
Our base exception includes a field for exception number.
What I would like to do is to run a script that creates a list with exception name, number and xml documentation.
Any idea how to do this?
If you want to generate a list of the custom exceptions in your application, you can use XML comments for this task. See the accepted answer to this question. As far as I know, the comments will not be able to access the error number property, but you can add an XML comment to that property and state the error number there.
