Access config file from a VS Sharepoint Workflow

I want to store some setting in web.config file of the sharepoint web application or in app.config of the workflow itself. But开发者_如何转开发 i don't know how to access neither of these files and i don't know how to handle the data inside them. Please, give some advise, how to do this or where to read about doing this.

Any information is helpful. Alexandr.

Alexandr, you will need to use the SPWebConfigModification class from the Microsoft.SharePoint.Administration namespace to make any modifications to your web application's web.config file. It's no easy task but I've done it several times before. If you'd like more detailed instructions please let me know.

EDIT: I'll stop being lazy now and give you some links to get you started. Here ya go!
