如何使Settings.settings数据持久化

Question

I have a Windows Forms application and I'm using the Settings.settings class to store user's configuration (email preferences, theme, etc) I didn't realize that after the user closes the app, the settings are gone!!

This app is about to be released to production, so I have to provide a solution ASAP.

Answer 1

You do have to save them after you set them. Have you tried:

Properties.Settings.Default.Save();

Answer 2

Are you using them like this?

... changes ...
Properties.Settings.Default.Save();
