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 = .         


        

Answer 1

One more option that I saw is missing here:

const string APP_CONFIG_FILE = "APP_CONFIG_FILE";
string defaultSysConfigFilePath = (string)AppDomain.CurrentDomain.GetData(APP_CONFIG_FILE);
