Initialization files known as INI files provide a standard means for storing configuration information for software in a text file. Although rarely used by .NET applications, there are situations where these files must be read and written to using C#.
Older versions of Microsoft Windows used INI files to store configuration information for the operating system and its applications. These are simple text files that can be edited using software such as Notepad. They hold a series of key / value pairs organised into categories where all of the category names, key names and values are held as strings.
Here is the sample INI file
In this section, I’ll talk about one of the class used to read and write INI document, aka ChoIniDocument. This class represents an INI document. It is an in-memory (cache) tree representation of an INI document and enables the navigation and editing of this document. Members of this class is NOT thread-safe.
Lets see how we can load a INI document.
1. Add reference to Cinchoo.Core.dll assembly
2. Namespace Cinchoo.Core.Ini
static void Main(string args)
using (ChoIniDocument iniDocument = ChoIniDocument.Load(@"C:\Temp\TestIni1.ini"))
Below are the different overloads of ChoIniDocument can be used creates a new INI document from a file specified by a URI, from an TextReader, or from text.
public static ChoIniDocument Load(Stream stream, ChoIniLoadOptions loadOptions);
public static ChoIniDocument Load(TextReader reader, ChoIniLoadOptions loadOptions);
public static ChoIniDocument Load(string path, ChoIniLoadOptions loadOptions);
public static ChoIniDocument Parse(string text, ChoIniLoadOptions loadOptions);
Where ChoIniLoadOptions is the options used by the loading process, contains the below numbers
- NameValueSeperator (char) – Name Value Seperator (default, ‘=’)
- CommentChars (string) – Possible Comment Characters (default, “#;”)
- IgnoreValueWhiteSpaces (bool) – true, Ignore White Spaces (default, false)
