Getting started

Library is prepared as .NET Standard 2.0. Code can be easily adjusted to any other project type.

Simple payment:

Dim Data As New PayBySquareTextGenerator.PayBySquareOverkill("CZ1720100000002800266981", 1235.8D, "EUR", "654321", "PayBySquareOverkill")

    .BankAccounts.Add(New BankAccount("CZ1720100000002800266981", "FIOBCZPPXXX"))
    .VariableSymbol = "654321"
    .ConstantSymbol = "0308"
    .SpecificSymbol = "998877"
    .PaymentNote = "PayBySquareOverkill note"
    .PaymentDueDate = New Date(2019, 1, 1)
End With
Dim Data As New PayBySquareTextGenerator.PayBySquareOverkill(Payment)
Dim Text As String = Data.GeneratePayBySquareOverkillString

Next step?

Transfer generated text to QR code using free online generators or custom library.

QR code Error correction level "Medium" is suggested.

C# implementation

Everything except LZMA namespace can be easily rewriten for C#.

LZMA namespace is based on C# managed-lzma project: https://github.com/weltkante/managed-lzma

Do NOT rewrite this LZMA namespace back to C#, that would be waste of time. Link to managed-lzma project directly (start with ManagedLzma.LZMA.AsyncEncoder) or use it's content to replace local code structure.
