How to find path of active app.config file?

Question

I'm trying to finish this exception handler:

if (ConfigurationManager.ConnectionStrings["ConnectionString"]==null) {     string pathOfActiveConfigFile = ...?     throw new ConfigurationErrorsException(        "You either forgot to set the connection string, or " +        "you're using a unit test framework that looks for  "+        "the config file in strange places, update this file : "         + pathOfActiveConfigFile); } 

This problem seems to only happen to me when I'm using nUnit.

Try this

AppDomain.CurrentDomain.SetupInformation.ConfigurationFile
