  1. public static Dictionary < stringstring > GetConfigFileAsDict(string sectionName) {  
  2.  Dictionary < stringstring > resultDictionary = new Dictionary < stringstring > ();  
  3.  try {  
  4.   Configuration configuration = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);  
  5.   if (configuration.GetSection(sectionName) is ConfigFileSection section) {  
  6.    foreach(ConfigFileElement element in section.Settings) {  
  7.     if (element.Value != null && element.Value != "")  
  8.      resultDictionary.Add(element.Key, element.Value);  
  9.    }  
  10.   }  
  11.   
  12.  } catch (Exception e) {  
  13.   //Throw error
