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.
