How to save user settings programmatically?
Solution 1
Set
Properties.Settings.Default.myColor = Color.AliceBlue;
Get
this.BackColor = Properties.Settings.Default.myColor;
Save
If you want to persist changes to user settings between application sessions, call the Save method, as shown in the following code:
Properties.Settings.Default.Save();
Solution 2
Take a look at this article, especially at Saving User Settings at Run Time section.
To have this answer not just be a link. Here is the relevant section reproduced:
Saving User Settings at Run Time
Application-scope settings are read only, and can only be changed at design time or by altering the .exe.config file in between application sessions. User-scope settings, however, can be written at run time, just as you would change any property value. The new value persists for the duration of the application session. You can persist changes to user settings between application sessions by calling the Settings.Save
method. These settings are saved in the User.config file.
To Write and Persist User Settings at Run Time
Access the user setting and assign it a new value, as shown in the following example:
Properties.Settings.Default.myColor = Color.AliceBlue;
If you want to persist changes to user settings between application sessions, call the Save method, as shown in the following code:
Properties.Settings.Default.Save();

I have a button which opens windows color pallet and then assigns select color to selected element in some virtual studio. Element is first selected by the user on mouse click, and based on element ID, color is assigned. So, each time the button is clicked, color of the same or different element is changed. Element ID is obtained from a delegate that fires if mouse clicked on some element. The code for color-set button is like this:
private void Btn_Choose_Color_Click(object sender, RoutedEventArgs e) { uint id_selected = (uint)selected_element; //get id of selected element from clickintocallback //open windows color dialog System.Windows.Forms.ColorDialog my_dialog = new System.Windows.Forms.ColorDialog(); my_dialog.ShowDialog(); //get the color from windows dialog int red = my_dialog.Color.R; int green = my_dialog.Color.G; int blue = my_dialog.Color.B; //create cinector color object and pass rgb values from windows dialog ByteRGBColor desired_color = new ByteRGBColor((byte)red, (byte)green, (byte)blue); //assign color statically for (int i = 0; i < all_color_elements_in_loaded_studio.Count; i++) { uint id_current = all_color_elements_in_loaded_studio.ElementAt(0).colorElementID; //get id of current element in a loop if(id_current == id_selected) //compare selected and current element { //all_color_elements_in_loaded_studio.ElementAt(i).colorElementColor = test_color; //set the test color instance.SetStudioColorElement(id_current, desired_color); //assign the color to the element break; } } //after we choose a color Btn_Pick_Element_Clicked = false; Btn_Choose_Color.IsEnabled = false; }
Now, my question is how to save element ID and its color once assigned into user settings? I understand that I can go to Properties->Settings and manually define user settings there, but here it must be done somehow programmatically. And then also, how to load these settings back?
