Question & Answer :
Is location immoderate people successful the .Nett model that tin publication/compose modular .ini information:
[Conception] <keyname>=<worth> ...
Delphi has the TIniFile constituent and I privation to cognize if location is thing akin for C#?
Preface
Firstly, publication this MSDN weblog station connected the limitations of INI information. If it fits your wants, publication connected.
This is a concise implementation I wrote, utilising the first Home windows P/Invoke, truthful it is supported by each variations of Home windows with .Nett put in, (i.e. Home windows ninety eight - Home windows eleven). I hereby merchandise it into the national area - you’re escaped to usage it commercially with out attribution.

EXE + ".ini").FullName; } national drawstring Publication(drawstring Cardinal, drawstring Conception = null) { var RetVal = fresh StringBuilder(255); GetPrivateProfileString(Conception ?? EXE, Cardinal, "", RetVal, 255, Way); instrument RetVal.ToString(); } national void Compose(drawstring Cardinal, drawstring Worth, drawstring Conception = null) { WritePrivateProfileString(Conception ?? EXE, Cardinal, Worth, Way); } national void DeleteKey(drawstring Cardinal, drawstring Conception = null) { Compose(Cardinal, null, Conception ?? EXE); } national void DeleteSection(drawstring Conception = null) { Compose(null, null, Conception ?? EXE); } national bool KeyExists(drawstring Cardinal, drawstring Conception = null) { instrument Publication(Cardinal, Conception).Dimension > zero; } } }
However to usage it
Unfastened the INI record successful 1 of the three pursuing methods:
// Creates oregon hundreds an INI record successful the aforesaid listing arsenic your executable // named EXE.ini (wherever EXE is the sanction of your executable) var MyIni = fresh IniFile(); // Oregon specify a circumstantial sanction successful the actual dir var MyIni = fresh IniFile("Settings.ini"); // Oregon specify a circumstantial sanction successful a circumstantial dir var MyIni = fresh IniFile(@"C:\Settings.ini");
You tin compose any values similar truthful:
