How to Write to a User.Config file through ConfigurationManager?
- by Josh G
I'm trying to persist user settings to a configuration file using ConfigurationManager.
I want to scope these settings to the user only, because application changes can't be saved on Vista/Win 7 without admin privileges.
This seems to get me the user's configuration, which appears to be saved here in Win 7 ([Drive]:\Users\[Username]\AppData\Local\[ApplicationName]\[AssemblyName][hash]\[Version\)
Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.PerUserRoamingAndLocal);
Whenever I try to save any changes at all to this config I get this exception:
InnerException: System.InvalidOperationException
Message="ConfigurationSection properties cannot be edited when locked."
Source="System.Configuration"
StackTrace:
at System.Configuration.SectionInformation.VerifyIsEditable()
at System.Configuration.MgmtConfigurationRecord.GetConfigDefinitionUpdates(Boolean requireUpdates, ConfigurationSaveMode saveMode, Boolean forceSaveAll, ConfigDefinitionUpdates& definitionUpdates, ArrayList& configSourceUpdates)
I have tried adding a custom ConfigurationSection to this config. I have tried adding to the AppSettingsSection. Whenever I call config.Save() it throws the exception above.
Any ideas?
I tried using the ApplicationSettingsBase class through the Project-Settings designer, but it doesn't appear that you can save custom types with this. I want similar functionality with the ability to save custom types.
Thanks.
