访问和覆盖类库中App.config文件中的值

Question

I gone through lot of threads about this topic but did not get any solution.

First I created a windows application. In that I used app.config file to store some variables it worked properly. Then the application converted to class library. While extracting the varibles it gives only null values.

Any other option to get or set variables in config file in the class library

Thanks.

Answer 1

If you converted you code to some class library you have to remember that it will reuse web.config/app.config of an application, which references it. So I would suggest to add settings from "old" app.config to the configuration file of an application, which uses your library.

Answer 2

We can not use app.config or web.config in class library. Add app.config for Console/Windows application or web.config file for your web application which calls your class library then application will automatically takes and uses that configuration file.
