  You can use

  1. string WorkID = ConfigurationManager.AppSettings["WorkID"];  

   but for this to work you will need to add assembly reference for 

  System.Configuration;

  To do that ,

  Go to your Solution Explorer and right click on References and select Add reference. Select the Assemblies tab and search for Configuration. 

   

   

  now you will be able to add the using statement

  using System.Configuration.

  If you want single key value in a variable usebelow code with namespace
  using System.Configuration;
  

  1. string WorkID = ConfigurationManager.AppSettings["WorkID"];

  Hi,

   

  Try this solution

   

   List values = new List();
  foreach (string key in ConfigurationManager.AppSettings)
  {
  if (key.StartsWith("KeyName"))
  {
  string value = ConfigurationManager.AppSettings[key];
  values.Add(value);
  }
  
  }
  
  string[] repositoryUrls = values.ToArray();

  Hi,

   

  Please use this to find all keys from Appsettings,

  1. string[] appSettingKeys = ConfigurationManager.AppSettings.AllKeys  
  2.                                    .Select(key => ConfigurationManager.AppSettings[key])  
  3.                              .ToArray();  

  Or if you want sepecific then you can add where clause,

  1. string[] appSettingKeys = ConfigurationManager.AppSettings.AllKeys  
  2.                              .Where(key => key.StartsWith("WorkID"))  
  3.                              .Select(key => ConfigurationManager.AppSettings[key])  
  4.                              .ToArray();
