I can't get data from my App.config

I'm trying to get data from my App.config and searching about I have found up to 4 ways to get that data, but basically you should use
ConfigurationManager.AppSettings["NameKey/NameSetting"];
My App.config code is
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<configSections>
<sectionGroup name="userSettings" type="System.Configuration.UserSettingsGroup, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089">
<section name="DXThemeManager" type="System.Configuration.ClientSettingsSection, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" allowExeDefinition="MachineToLocalUser" requirePermission="false" />
</sectionGroup>
<sectionGroup name="applicationSettings" type="System.Configuration.ApplicationSettingsGroup, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" >
<section name="InterfazPrueba1.Properties.Settings" type="System.Configuration.ClientSettingsSection, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
</sectionGroup>
</configSections>
<userSettings>
<DXThemeManager>
<setting name="ApplicationThemeName" serializeAs="String">
<value>Office2016White</value>
</setting>
</DXThemeManager>
</userSettings>
<applicationSettings>
<InterfazPrueba1.Properties.Settings>
<setting name="HostBD" serializeAs="String">
<value>LOCALHOST</value>
</setting>
<setting name="NombreBD" serializeAs="String">
<value>Pruebas1</value>
</setting>
<setting name="ServerBD" serializeAs="String">
<value>DESKTOP-O037RKH</value>
</setting>
<setting name="InstanceBD" serializeAs="String">
<value />
</setting>
<setting name="UsuarioBD" serializeAs="String">
<value>sa</value>
</setting>
<setting name="PassBD" serializeAs="String">
<value>123</value>
</setting>
</InterfazPrueba1.Properties.Settings>
</applicationSettings>
</configuration>
And the code in my class is:
private void datosConexion()
{
server = ConfigurationManager.AppSettings["ServerBD"];
user = ConfigurationManager.AppSettings["UsuarioBD"];
pass = ConfigurationManager.AppSettings["PasswordBD"];
host = ConfigurationManager.AppSettings["HostBD"];
db= ConfigurationManager.AppSettings["NombreBD"];
instance = ConfigurationManager.AppSettings["InstanceBD"];
Console.WriteLine("Datos:"+server + user + pass + host + db + instance);
}
All the variables have nothing.
I've tried all the ways I've seen and changed the values to keys but I just can retrieve the data...
Any idea about what is wrong or what am I doing bad?
Thank you for all the support you could give me.

ConfigurationManager.AppSettings["NameSetting"] retrives a setting that is defined in the App.config like this:
<configuration>
<configSections>
...
</configSections>
<userSettings>
...
</userSettings>
<appSettings>
<add key="NameSetting" value="123" />
</appSettings>
</configuration>
If you add project specific settings under Project->Properties->Settings you can access these through a class that gets generated for you:
string setting = InterfazPrueba1.Properties.Settings.Default.HostBD;

Application settings reset when exe changes location [duplicate]

Settings.settings File Keeps Getting Reset

Hi I'm using the Visual Studio config files, however the settings change every time I move the exe.
How can I fix this?

The actual configuration file containing saved configuration settings is stored here:
%APPDATA%\Local\<application name>\<application name>.<eid>_<hash>\<version>
According to this MSDN article::
<eid> is the URL, StrongName, or Path, based on the evidence available to hash.
<hash> is a SHA1 hash of evidence gathered from the CurrentDomain, in the following order of preference:
StrongName
URL
If neither of these is available, use the .exe path.
(my emphasis)
So the solution seems simple:
Create a strong name and sign your executable.
Then you will get the same unique hash every time and it won't change whenever you start the executable from a new location.
If you need help signing your application, please refer to this MSDN article: How to: Sign an Assembly with a Strong Name.

The user settings will be stored in your user's profile in such a way that the location of your application is linked. That's why the application, when moved, does not find the settings anymore.
What you can try to do is:
Create a new user setting named SettingsUpgradeRequired and set it to true in the settings designer in Visual Studio.
In your application's startup code, check whether SettingsUpgradeRequired is true and if so, perform a settings upgrade.
As the new setting will only be true after the settings file was reset, the following should import the old settings, and it should do so only once:
if (Properties.Settings.Default.SettingsUpgradeRequired)
{
try
{
Properties.Settings.Default.Upgrade();
Properties.Settings.Default.SettingsUpgradeRequired = false;
Properties.Settings.Default.Save();
}
catch (...)
{
... // Upgrade failed - tell the user or whatever
}
}

That behavior is by design because you could have multiple versions of you application (for instance a QA version, a PROD version and so on) that requires different setting storages. See also Client Settings FAQ for details.
If you need a settings management that is independend of the location / version of you app, i would suggest wo create your own settings file and store them below "%appdata%[company][application]"

C# - Compiler Error: System.Configuration.ConfigurationErrorsException was unhandled

Hey Everyone,
How do I fix the Compiler Error upon compiling on "return ((string)(this["TargetDir"]));":
System.Configuration.ConfigurationErrorsException was unhandled
Configuration system failed to initialize
{"Unrecognized configuration section userSettings/CCP.Settings1. (C:\\Users\\bmccarthy\\Documents\\Visual Studio 2008\\Projects\\CCP Utility\\CCP Utility\\bin\\Debug\\CCP_Utility.exe.config line 21)"}
A first chance exception of type 'System.Configuration.ConfigurationErrorsException' occurred in System.Configuration.dll
Here's the code in my Settings.Designer.cs file under the Properties directory:
[global::System.Configuration.UserScopedSettingAttribute()]
[global::System.Diagnostics.DebuggerNonUserCodeAttribute()]
[global::System.Configuration.DefaultSettingValueAttribute("")]
public string TargetDir {
get {
return ((string)(this["TargetDir"]));
}
set {
this["TargetDir"] = value;
}
}
Here's the code for CCP_Utility.exe.config from the bin folder:
<CCP_Utility.Properties.Settings>
<setting name="SourceDir" serializeAs="String">
<value />
</setting>
<setting name="TargetDir" serializeAs="String">
<value />
</setting>
<setting name="CorpID" serializeAs="String">
<value />
</setting>
</CCP_Utility.Properties.Settings>
<CCP_Utility.Settings1>
<setting name="sourceDir" serializeAs="String">
<value />
</setting>
<setting name="targetDir" serializeAs="String">
<value />
</setting>
</CCP_Utility.Settings1>
What does the < CCP_Utility.Settings1 > tag have to match up to?? App.config and what else?
Does capitalization matter? I have the variable declared as TargetDir Settings.Settings....
Where is the System.Configuration.dll file located?

I got the application to compile without compiler errors by changing the capitilzation of sourceDir and targetDir under CCP_Utility.Settings1 in the Settings1.Designer.cs file as follows:
<CCP_Utility.Settings1>
<setting name="SourceDir" serializeAs="String">
<value />
</setting>
<setting name="TargetDir" serializeAs="String">
<value />
</setting>
</CCP_Utility.Settings1>

Verify UserScopedSettingAttribute matches up with the correct settings section.
If I remember correct, yes, case-sensitive.
Usually, I will add a setting, save and close, then open the settings designer again, and delete the setting, save and close. This will get the designer in-sync. I have seen them get out-of-sync the first time the designer is opened on a computer. (For example, when you get from source control.)

web.release.config change dynamic webservice url

I'm editing my web.release.config file for production. I want the web.config file changed after a publish.
I found how to change the web.config by using the web.release.config file properly, but not for this particular component.
The URL of an dynamic webservice has to change.
In the web.config:
<applicationSettings>
<FooService.Properties.Settings>
<setting name="FooService_Student" serializeAs="String">
<value>http://testwebservices.foo.bar.nl/Student.asmx</value>
</setting>
<setting name="FooService_User" serializeAs="String">
<value>http://testwebservices.foo.bar.nl/User.asmx</value>
</setting>
</FooService.Properties.Settings>
</applicationSettings>
now, how do I change the <value> in both settings? I tried the following, but that didn't work out:
<configuration xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform">
<applicationSettings>
<FooService.Properties.Settings>
<setting name="FooService_Student" serializeAs="String" xdt:Transform="Replace">
<value>http://webservices.foo.bar.nl/Student.asmx</value>
</setting>
<setting name="FooService_User" serializeAs="String" xdt:Transform="Replace">
<value>http://webservices.foo.bar.nl/User.asmx</value>
</setting>
</FooService.Properties.Settings>
</applicationSettings>
</configuration>
Anyone experience with this matter?
Thankyou!

Add xdt:Transform="Replace" to the applicationSettings tag.
<applicationSettings xdt:Transform="Replace">
<FooService.Properties.Settings>
<setting name="FooService_Student" serializeAs="String">
<value>http://webservices.foo.bar.nl/Student.asmx</value>
</setting>
<setting name="FooService_User" serializeAs="String">
<value>http://webservices.foo.bar.nl/User.asmx</value>
</setting>
</FooService.Properties.Settings>

How about adding a xdt:Locator="Match(name)", that will probably be what you need to find the exact nodes to replace.

ConfigurationManager.AppSettings[key] is always null

I am trying to get the value for the key "sUser" in appSetting section from app.config
this is the code on my class.cs
string sUsr = ConfigurationManager.AppSettings.Get["sUser"];
But always its null.
I try this code (I took it from MSDN):
// Get the configuration file.
Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
// Get the appSettings section.
AppSettingsSection appSettings = (AppSettingsSection)config.GetSection("appSettings");
// Get the auxiliary file name.
Console.WriteLine("Auxiliary file: {0}", config.AppSettings.File);
But it shows that the file Empty
Also I am using the stting console to write those properties and it works if I get the apps using
string sUsr = WIW.Business.Properties.Settings.Default.sUser;
But I am going to use that class as a reference in a website and on the web.config of the site I can't configure those settings

In your App.config the appSettings section should look like the following:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<appSettings>
<add key="sUser" value="Test"/>
</appSettings>
</configuration>

use Properties.Settings.Default.{your_setting_key} to access the value
I.E
Properties.Settings.Default.sPassword return 8909039388
All these were included in Properties Class.

I had the same problem. I was calling another project(In the same solution) and was expecting the appSettings to be present.
To make it work,I added the following lines in the application that was calling the target application.
<appSettings>
<add key="sUser" value="Test"/>
</appSettings>
It worked for me after that. Try this. It might help you too

Here its my app.config, if I try to get the key values from the appSettings sections I always get null, but If I try to get them from applicationsection Its no problem, the thing is that I need put that applicationsection on a web site but on a web site i can put applicationSettings
<configuration>
