Load data from App.config and connect to property

Question

I have defined:

public static string Firstname { get; set; }
public static string Surname { get; set; }
public static bool DocBook5 { get; set; }
public static string Language { get; set; }

I stored that information in a App.config.

Then i used that to load and connect:

Firstname = ConfigurationManager.AppSettings["firstname"];
Surname = ConfigurationManager.AppSettings["surname"];
DocBook5 = Convert.ToBoolean(ConfigurationManager.AppSettings["docbook5"]);
Language = ConfigurationManager.AppSettings["language"];

But if i'm giving out the properties content with Console.WriteLine it looks like the properties are empty. The full code of the GetConfig class can be shown there

Maybe anyone knows why?

Can you share you app.config ? And you project is this a console application or web? — Yashveer Singh, Jan 16 '17 at 08:52
You keys are located under node not under AppSetting .And your code is reading from appsetting section . so you are getting blank result — Yashveer Singh, Jan 16 '17 at 08:56
Your code works fine I just tested it. Check your app.config — Softe Eng, Jan 16 '17 at 08:59
@Yashveer Sing: Thanks for answering. I'm using the static properties for usage inside a static class. But maybe i'm wrong. It's just my first C# app. — Sascha Manns, Jan 16 '17 at 09:47
no it will be fine if you are using these values at many place in your application. — Yashveer Singh, Jan 16 '17 at 11:05
Just now i added the link to the GetConfig class. Also i put all stuff from userSettings to appSettings. I added on the bottom of the class a little checker, which prints the content of the properties. But nothing is set now. Or do i use a false way to check it? — Sascha Manns, Jan 16 '17 at 11:18

As mentioned in my comments you are reading the wrong section not from appsetting . If you need a custom section in you config please follow this link .http://haacked.com/archive/2007/03/12/custom-configuration-sections-in-3-easy-steps.aspx/ else move them to appsetting section

Look at your App.config. The data you stored is in UserSettings and not in appSettings, but you fetched the data from appSettings.

Either you put all your data in appSettings, or you define configSections, in which you add the name UserSettings. (Use 'GetSection' instead of ' AppSettings')

Later, in code, you need to request the specific section, and get the data from there.

Edit: Let me know if you want code example, to match your App.config file

Hi Ori, can you provide a code example please? I tried it out like so: ConfigurationManager.GetSection("firstname").ToString(); but that doesn't work. – Sascha Manns Jan 16 '17 at 09:45
You want to get the section 'UserSettings' (Working on it) – Ori Nachum Jan 16 '17 at 10:02
Yes. That would be great :-) – Sascha Manns Jan 16 '17 at 10:13
Trying to make this work (I have this in my code, but it's not accessible current - I'm at work) Check out the question here: http://stackoverflow.com/questions/20195198/how-to-use-configurationmanager-appsettings-with-a-custom-section – Ori Nachum Jan 16 '17 at 10:28
