Get Configuration File As Dictionary In C#

In this blog, you will learn how to get configuration file or file section As Dictionary In C#.

To achieve this, we can use the following namespace: "System.Configuration". Here is a custom code snippet, where the single parameter is the sectionName. sectionName parameter will hold the section name of a configuration file which you want as key-value pair.

public static Dictionary < string, string > GetConfigFileAsDict(string sectionName) {
 Dictionary < string, string > resultDictionary = new Dictionary < string, string > ();
 try {
  Configuration configuration = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
  if (configuration.GetSection(sectionName) is ConfigFileSection section) {
   foreach(ConfigFileElement element in section.Settings) {
    if (element.Value != null && element.Value != "")
     resultDictionary.Add(element.Key, element.Value);
   }
  }

 } catch (Exception e) {
  //Throw error
 }
 return resultDictionary;
}
