IniFiles.Net is a small library to simplify using standard .ini files in .NET. Heavily loaning from Delphi inifiles functionality, it implements similar methods for reading and writing to ini files.
As of now, only TMemIniFile is fully functional, if somewhat untested. I expect to update the library with regular TIniFile functionality soon.
Library is written in C# (namespace IniFiles), you can include IniFiles.Net.dll to your project or simply include MemIniFile.cs.
