C# ASP MVC pulling data from the web config file is not working

I'm trying to pull data from the web config file as outlined by this msdn resource.

Here is my code: 

System.Configuration.Configuration activeCampaignApiSetting1 =
  System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration(null);
if (activeCampaignApiSetting1.AppSettings.Settings.Count > 0) {
    System.Configuration.KeyValueConfigurationElement activeCampaignApiKeySetting =
      activeCampaignApiSetting1.AppSettings.Settings["ActiveCampaignApiKey"];
    if (activeCampaignApiKeySetting != null) {
        activeCampaignApiKey = activeCampaignApiKeySetting.Value;
    }

    System.Configuration.KeyValueConfigurationElement activeCamapignApiUrlSetting =
      activeCampaignApiSetting1.AppSettings.Settings["ActiveCampaignApiUrl"];
    if (activeCamapignApiUrlSetting != null) {
        activeCampaignApiUrl = activeCamapignApiUrlSetting.Value;
    }
}

When I try to instantiate this class:

var acs = new Acs(activeCampaignApiKey, activeCampaignApiUrl);

it throws an exception telling me that the values are blank.

The values in the web config file are there:

<add key="ActiveCampaignApiKey" value="apikey_removed" />
<add key="ActiveCampaignApiUrl" value="apiurl_removed" />

Anyone know where I may be going wrong? Cheers

Ok so I have a better solution,

As I'm working with nopCommerce I need to use:

private readonly ISettingService _settingService = EngineContext.Current.Resolve<ISettingService>();

string apikey = _settingService.GetSettingByKey<string>("apikey_removed");
string apiurl = _settingService.GetSettingByKey<string>("apiurl_removed");

As outlined in this forum thread

Then in the administration backend under configuration > settings > all settings I add the key there.

This is a much better solution because if the api key or url ever need to be changed it can be done through the nopcommerce administration panel. rather than rebuilding/publishing the solution to a web server.

Hope this helps someone :)

If they are appSetting inside web.config, you can access them via ConfigurationManager.AppSettings. 

<?xml version="1.0"?>
<configuration>
   <configSections>
      <appSettings>
         <add key="ActiveCampaignApiKey" value="apikey_removed" />
         <add key="ActiveCampaignApiUrl" value="apiurl_removed" />
      </appSettings>
   </configSections>
</configuration>

string activeCampaignApiKeySetting 
 = ConfigurationManager.AppSettings["ActiveCampaignApiKey"];

string activeCamapignApiUrlSetting 
 = ConfigurationManager.AppSettings["ActiveCampaignApiUrl"];

Please make sure you reference System.Configuration, and include using System.Configuration; directive.

FYI: They return string value (not key value pair).
