How to save EDITABLE application settings? RRS feed

  • Question

  • The My.Settings class is great for handling user settings. The PropertyGrid control makes editing settings very easy. But application settings are read-only. They can only be changed in the VS IDE (Community 2017 VB/C#). This leaves out settings that apply to all users and that can change, even if infrequently.

    In the past, I've persisted these settings in text files I read in when the application starts. The added benefit is that the settings can be changed with Notepad. I can continue doing it this way, but aside from My.Settings, is there an alternative within .NET?

  • Hi Robert in SF,

    Thank you for posting here.

    For your question, I suggest you to use Properties.Settings.

    You could set the settings in the Properties of project> Settings.

    Here is the simple code for your reference.

      Properties.Settings.Default.FileList3 = "Hello";

    FileList3 is the string I defined in the Settings.

    For more details, please refer to the MSDN document.

  • Thanks for your response, Wendy. Unfortunately, while Properties.Settings (and My.Settings in VB) is a great feature, the application-level settings are not editable except in the IDE.

    I've concluded there is no way except to use a database or text file or even XML. Fortunately, ReadAllLines makes it easy to read text files.
