Reading specific config file

I made my custom configuration classes to parse data from my config section. My project is class library which means it creates dll. I found this way to retrieve my config section:

return (ReportServerConfigurationSection)ConfigurationManager.GetSection(sectionGroup + "/" + sectionName);

How to read from app.dll.config file?
