I am trying to read StartingMonthColumn and CategoryHeadingColumn from the below app.config file using the code
ConfigurationSettings.AppSettings[\"StartingM
The reason is simple, your call to ConfigurationSettings.AppSettings
is not returning the required config file. Please try any of the following ways:
ConfigurationManager.OpenExeConfiguration(Assembly.GetExecutingAssembly().Location).AppSettings["StartingMonthColumn"]
Hope this helps
