Why does my C# Config file not load the settings after saving them?

I’m trying to write my Textbox Text into a config file in C# Winfroms to save the text. This is what I have done so far:

The settings:

The code to save the settings:

Properties.Settings.Default.saveToTextBox = saveToTextBox.Text;

The code to load the settings:

saveToTextBox.Text = Properties.Settings.Default.saveToTextBox;

`

And the Events FormClosed and Load to save and load it.

But if I reopen my program the textbox remains empty.

>Solution :

To persist the changes to Settings between application sessions, call the Save method:

Properties.Settings.Default.Save();  

This should work both for .NET Framework 4 and for .NET 6/7.

Settings are saved in a file within a subfolder of the user’s local hidden application data folder.
