"如何防止在每次新安装后重置 settings.settings 文件"

Question

So I have WPF application and I am using settings.settings file to save several settings for example specific Path that the user need to set and I am also create a exe installation file using Advanced installer and after install new application version all the application files (include the application exe file) replaced with the new version and in such case all settings.settings variables reset and I want to prevent it.

Any ideas ?

Answer 1

If I understand correct, when you upgrade your application you want your settings.settings file to be saved. If you don't want to use "Side by side install", you can do this:

Answer 2

For Windows Forms apps I use code like this in my main form, after the call to InitializeComponent(). It copies the settings from the previous version the first time the new version runs.

if (Properties.Settings.Default.FirstTimeRunningThisVersion)
{
   Properties.Settings.Default.Upgrade();
   Properties.Settings.Default.FirstTimeRunningThisVersion=false;
   Properties.Settings.Default.Save();
}
