Accessing Values from configSections of App.Config of different application

Question

I am trying to read values from the different configSections of App.Config file from a different application using this code:

public string ReadValue(string FileName,string Key)
        {
     //File name is the path of the App.Config from a different application
         ExeConfigurationFileMap configMap = new ExeConfigurationFileMap();
         configMap.ExeConfigFilename = FileName;

         Configuration config = System.Configuration.ConfigurationManager.OpenMappedExeConfiguration(configMap, ConfigurationUserLevel.None);

         var section =config.GetSection("dev") as AppSettingsSection ;
            return section[Key];


         }

I am getting error as System.Configuration.ConfigurationElement.this[System.Configuration.ConfigurationProperty]' is inaccessible due to its protection level

How do I get this code working? Thanks
