Library for INI file reading and writing.
This example INI file is used in the examples.
global_prop1 = hello
global_prop2 = world
[section1]
key1 = value1
key2 = value2
[section2]
key3 = value3
; A section that occurs multiple times
[section2]
key4 = value 4
Read INI file
Load INI file and retrieve a property:
The Section and Property methods are accessors; The collections of sections and properties can also be queried using LINQ.
// Load INI file:
IniFile iniFile = IniFile.FromFile(@"C:\path\to\file.ini");
// Retrieve "section1"
if (iniFile.Section("section1", true) is IniSection section1) // true = ignore case
{
// Retrieve property "key1"
IniProperty? property = section1.Property("key1", true); // true = ignore case
if (property != null)
{
// Property value:
string value = property.Value;
}
}
Loop through all sections & properties
Loop through the entire contents of an INI file:
// Load INI file:
IniFile iniFile = IniFile.FromFile(@"C:\path\to\file.ini");
// "global properties" are properties without a section. They are on top of the INI file
foreach (IniProperty globalProperty in iniFile.GlobalProperties.Properties)
{
Console.WriteLine($"Name: {globalProperty.Name}, Value: {globalProperty.Value}");
}
// Loop through all sections:
foreach (IniSection section in iniFile.Sections)
{
// Loop through section properties:
foreach (IniProperty property in section.Properties)
{
Console.WriteLine($"Section: {section.Name}, Name: {property.Name}, Value: {property.Value}");
}
}
IniFileParsingOptions
This class is a set of rules that is applied when reading an INI file.
IniFileParsingOptions parsingOptions = new()
{
PropertyDelimiter = IniPropertyDelimiter.Colon,
DuplicatePropertyNameBehavior = IniDuplicatePropertyNameBehavior.Overwrite
// See XML comments for a documentation of each property
};
// Load INI file with custom parsing options:
IniFile iniFile = IniFile.FromFile(@"C:\path\to\file.ini", Encoding.UTF8, parsingOptions);
Write INI file
Either create an IniFile, or load an existing to modify it. Call IniFile.Save to save the new or modified INI file.
IniFile iniFile = new();
iniFile.GlobalProperties.Properties.Add("global_prop1", "hello");
iniFile.GlobalProperties.Properties.Add("global_prop2", "world");
IniSection setion1 = iniFile.Sections.Add("setion1");
setion1.Properties.Add("key1", "value1");
setion1.Properties.Add("key2", "value2");
iniFile.Save(@"C:\path\to\file.ini");
IniFileFormattingOptions
This class is a set of rules that is applied when writing an INI file.
IniFileFormattingOptions formattingOptions = new()
{
PropertyDelimiter = IniPropertyDelimiter.EqualSign,
UseNewLineBetweenSections = true
};
iniFile.Save(@"C:\path\to\file.ini", Encoding.UTF8, formattingOptions);
