Question

I have a problem: change setting in user control’s configuration file has no effect.

I can add “setting” to a user control project and can make following code work:

label1.Text = Properties.Settings.Default.DisplayName;

The output of this usercontrol project is “usercontorl1.dll” and “usercontrol1.dll.config”.

When I test it in other project, I found that change the value in config file has no effect to its display. And even if there is no config file, it works fine!

How can I solve this problem , I really need a configurable user control.

Thank you.

Writing/Reading User-Defined settings in app.config file

Answer 1

You need to copy the config section to the App.Config of the using project.

The (only) file used at runtime is AppName.exe.config
