National Register Number

National Register Number is a package that can generate and validate Belgian national register numbers. The logic is based on Official Documentation by the Belgian Government

Installation

dotnet add package WilvanBil.NationalRegisterNumber
Or find it on NuGet Package Manager.

Usage

After installation you can use the static class NationalRegisterNumberGenerator to generate or validate your national register numbers.

Validate

This will return true or false based on input.

NationalRegisterNumberGenerator.IsValid(string here)

Generate

This will return a string that's a valid national register number. Following overloads are possible on NationalRegisterNumberGenerator.Generate()

Generate()
Generate(DateTime birthDate)
Generate(BiologicalSex sex)
Generate(DateTime birthDate, BiologicalSex sex)
Generate(DateTime minDate, DateTime maxDate)
Generate(DateTime minDate, DateTime maxDate, BiologicalSex sex)
Generate(DateTime birthDate, int followNumber)

followNumber is a number (inclusive) between 1 and 998. If your parameters are invalid, it will throw an ArgumentException with a message why Generate() has failed. Keep in mind that the absolute minDate is 1900/01/01 and the absolute maxDate is Datetime.Today on the time that the code runs. If you pick a date outside this range, it will also throw an ArgumentException.

!!WARNING!!
