How Can I Create a Swiss QR Code V2.3?

The following sample code in C# .NET shows how to create the data format for Swiss QR Code according to the Swiss QR-bill Implementation Guidelines Version 2.3.

Version 2.3 requires structured addresses. The street, building number, postal code, and town must therefore be provided in separate fields. The address type must be set to S.

public enum CurrencyCodes
{
  CHF,
  EUR
}

public enum ReferenceTypes
{
  NON,
  SCOR,
  QRR
}

private const string fldSep = "\n";

decimal? Amount = new decimal(99.01);
CurrencyCodes Currency = CurrencyCodes.CHF;
ReferenceTypes ReferenceType = ReferenceTypes.SCOR;

string QRIBAN       = "";
string CreditorIBAN = "CH3908704016075473007";

// Structured creditor address

string CreditorPostalCode     = "2501";
string CreditorTown           = "Biel";
string CreditorCountry        = "CH";

// Structured debtor address

string DebtorStreet         = "Musterstrasse";
string DebtorBuildingNumber = "2";
string DebtorPostalCode     = "1234";
