How can i use connection strings from class lib's App.config?

Question

Hi there,

I have a class library and my other projects are using it. And also i have some connection strings. i want to use them from just class lib's App.config file. But when i use ConfigurationManager in my class lib for reading connection strings, program looks my current project's App.config or Web.config files.

How can i use connection strings from class lib's App.config file?

Thanks in advance

Answer 1

Copy them from the class lib's config file to the application's config file. See http://stackoverflow.com/questions/1742929/net-app-config-in-library-project

You have to provide a connection string in the end application.

Say you have a library.dll and application.exe

Classes in application.exe use library.dll. And classes in library.dll need connection string from App.config. Then you have to provide the connection string in App.config of your application.exe.

I think you need a Xml file in your class library. You should read your connection strings from it.
