Looping Through Application Settings

[Guest]

I have a Windows Form application with several application settings set. How
is it possible for me to loop through those settings? Is it possible at all?

Thank you

No - this is logically and technically impossible.

NameValueCollection settings;
settings = System.Configuration.ConfigurationManager.AppSettings;

foreach (string keyname in settings.AllKeys)
{
messagebox.show(keyname)
{

Hi,

As MWS suggested, the Settings is of type NameValueCollection and you can
use its AllKeys to iterate.

I'm not sure if this is what you wanted. Please feel free to let us know if
you have further questions. Thanks.

NameValueCollection settings;
settings = System.Configuration.ConfigurationManager.AppSettings;

foreach (string keyname in settings.AllKeys)
{
messagebox.show(keyname)
{

This returns the error "The type or namespace name 'ConfigurationManager'
does not exist in the namespace 'System.Configuration'. I have to use
System.Configuration.ConfigurationSettings.AppSettings.

And that does not return any of my app settings.

Hello RHPT,

This returns the error "The type or namespace name
'ConfigurationManager' does not exist in the namespace
'System.Configuration'. I have to use
System.Configuration.ConfigurationSettings.AppSettings.

And that does not return any of my app settings.

You need to add a reference to the System.Configuration to your project.
These classes used to reside in the .NET Core Assembly, but were moved to
a separate assembly for .NET 2.0.

Hi,

Are you using the Client Settings (created with the Settings Designer)? In
other words, you have a strong typed settings class and you access the
settings via strong typed property name:

Settings.Default.MyProperty


If this is the case, then the AppSettings will not help here since it's
using different approaches.


To get the property name list, you can use Settings.Default.Properties to
iterate them:

foreach (SettingsProperty sp in Settings.Default.Properties)
{
Console.WriteLine(sp.Name);
}

After you get the property name, then you can use reflection on the
Settings.Default object to get the property value. You can also use
SettingsProperty.DefaultValue to get the default value when you input in
the settings designer.

Thank you. This is what I was looking for. I should have asked my question
better.
