Basic usage

var petrovich = new Petrovich()
		FirstName = "Иван",
		LastName = "Иванов",
		MiddleName = "Иванович",
		Gender = Gender.Male

// Inflect all properties
var inflected = petrovich.InflectTo(Case.Dative);

System.Console.WriteLine(inflected.FirstName); // Ивану
System.Console.WriteLine(inflected.LastName); // Иванову
System.Console.WriteLine(inflected.MiddleName); // Ивановичу

inflected = petrovich.InflectTo(Case.Instrumental);

System.Console.WriteLine(inflected.FirstName); // Иваном
System.Console.WriteLine(inflected.LastName); // Ивановым
System.Console.WriteLine(inflected.MiddleName); // Ивановичем

// Inflect each property
System.Console.WriteLine(petrovich.InflectFirstNameTo(Case.Genitive)); // Ивана
System.Console.WriteLine(petrovich.InflectLastNameTo(Case.Genitive)); // Иванова
System.Console.WriteLine(petrovich.InflectMiddleNameTo(Case.Genitive)); // Ивановича

You can use automatic gender detection based on middle name or first and last names, if the middle name not determinates gender:

var petrovich = new Petrovich()
        FirstName = "Иван",
        LastName = "Иванов",
        MiddleName = "Иванович",
        AutoDetectGender = true

System.Console.WriteLine(petrovich.Gender); // Male

Also you can use GenderUtils to detect gender based on middle name:

Gender gender = GenderUtils.Detect("Иванович");
System.Console.WriteLine(gender); // Male

Advanced usage

You can use your own rules loader which implements IRulesLoader interface:

IRulesLoader customLoader = new CustomRulesLoader();
var petrovich = new Petrovich(customLoader);
