.NET Forum / Languages / C# / May 2007how to read/write settings (using .ini, xml, whatever)?
I want to read/write user settings. I thought about using .ini or .xml files. Are there classes in c# to handle this? The stuff I find on the 'net seems old.

If you're using vs 2005, you can open the Project properties, click on the Settings tab. You should get a link offering to create settings. Put application and user settings in there. YOu can then use them via Properties.Resources.Default. HTH Andy With that, can create a GUI to let the user change these settings? How are the saved from one session to the next (from one run of the program to the next time)? > > I want to read/write user settings. I thought about using .ini > > or .xml files.

Just numbers and strings. Without getting into the description of the program, the user has settings he/she may want to change. For example, there are delay settings in milliseconds. It might be set to 1,000 (one second), and the user may want to change that to 10,000 (ten seconds). There's also folder location settings for files, and many other things. I was going to put them into an .ini file, and have the user update the file, and have the program read the file. It is what I am working on right now. But, is there a better way? Titan I just thought of a problem... I want the user to be able to change settings for multiple instances of this program. It will be run on multiple computers. So, it would be a hassle to have the user go in and modify the settings on each program. What would be easiest, would be to have the settings inside a .ini file (text file) that the user modifies only once, and then copies to each instance of the program. So, that's what I want do to. Read in an .ini file. Sorry for jumping around. This is not typically what a software dev. would be wanting to do. So, is there a class in c# to read in .ini files? ~Titan >I just thought of a problem... I want the user to be able to change > settings for multiple instances of this program.

I tend to use XML documents for this, using the System.Xml namespace - this would allow you to do the copying etc... However, if you *really* want to use .ini files, you could do it fairly easily with a couple of API calls: http://www.pinvoke.net/default.aspx/kernel32/GetPrivateProfileString.html http://www.pinvoke.net/default.aspx/kernel32/WritePrivateProfileString.html  Signaturehttp://www.markrae.net > I just thought of a problem...

The method i suggested results in a text file, which could be modified. Although I think that's a bad idea. What if the user puts something unexpected in there? And its not the best way to share settings.. if you really want to share settings, typically this is done in some sort of database. Then it would be change once and done. > if you really want to > share settings, typically this is done in some sort of database. Then > it would be change once and done. I agree. I will think about how to do this more. ~titan > > What kind of settings do you need to store? > [quoted text clipped - 10 lines] > > Titan Hi, Andy suggested the best solution for you. The settings resource auto generates resources class that you can use to subscribe for "SettingChanging" etc. events. The auto generator creates an auto generated class that inherits ApplicationSettingsBase. Hope this helps.

I think that is the best solution, typcially. But now I just discovered I need the settings store in a text file, that can be modified by the user. I figured .ini files are the best option, and if c# supports them with any classes it would be great. ~titan > > Andy suggested the best solution for you. > [quoted text clipped - 9 lines] > > ~titan Hi, XML files in general are textual files, and they are pretty readable...
