Using Nini .NET Configuration Library
Using Nini .NET Configuration Library
When developing a desktop application, there will be times when you want to store settings for your program. A database is one option, but on Windows, you might just wish to have your settings stored in an INI file. One way to work with an INI file in C# is with the Nini Library. This makes it quite easy to read from and write to an INI file.
Let’s get started.
After installing the library, we’ll need to set our namespace.
What will our INI file look like? Something like this:
For my application, I decided to make a class devoted to the configuration file. So, let’s define that and a few other variables.

publicclassOurConfig
{
stringNL=Environment.NewLine;// New line character
privatestringconfigFile="conf.ini";// Our INI file
IConfigSource config;// Instance of our config
}
|
Now that we have our variables declared, let’s create a couple of useful methods.
These two methods will update the INI file with new settings, should we change them in our program. Of course, if we make these changes, they need to be saved. Thankfully, we can declare something in our constructor (which we will write a little later) that will auto-save our changes as we make them.
Now, let’s create a pair of methods to return the data. This will be useful in our program when we need to use these settings.
With these methods, we now have a basic class for handling a configuration file. All that is left is our constructor.
But before we get to the constructor, there is something else I created. What if our INI file doesn’t exist? I decided that I would make a function to create a default INI file, should the old one not exist anymore. This is also useful if we want to distribute our program without an INI file.
We can do a check when we initialize our class that will check to see whether or not this file exists. If not, we’ll create it so we can work with it.
That makes this our constructor:
Our whole class thus looks like this:
That’s how simple it can be to work with your own INI files in C#.
