Gs1Builder

public static class Gs1Builder

Helpers to build GS1 element strings ("(AI)value…") for the GS1 symbologies.

Method Signature	Returns	Description
static # `Build(params (string, string)[] elements)`	`string`	Element string of (AI, value) pairs, e.g. `Build(("01", gtin), ("10", "LOT1"))`.
static # `CheckDigit(string digits)`	`int`	GS1 mod-10 check digit of a digit string (GTIN, SSCC, GLN …).
static # `Date(string ai, DateOnly date)`	`string`	Date AI value YYMMDD, e.g. `Date("17", expiry)` for (17) expiration date.
static # `Element(string ai, string value)`	`string`	One element "(AI)value".
static # `Gtin(string gtin)`	`string`	AI (01): GTIN-8/12/13/14 padded to 14 digits; a 7/11/12/13-digit input gets its check digit.
static # `IsKnownAi(string ai)`	`bool`	True when the AI is defined in the GS1 table.
static # `IsValidCheckDigit(string digitsWithCheck)`	`bool`	True when the last digit is the correct GS1 check digit.
static # `Measure(string ai3, decimal value, int decimals)`	`string`	Measure AI with implied decimal point: `ai3` is the 3-digit base (e.g. "310" net weight kg), the 4th digit is the number of decimals; value padded to 6 digits. `Measure("310", 1.5m, 3)` → "(3103)001500".
static # `Sscc(string sscc)`	`string`	AI (00): SSCC from 17 digits (check digit added) or 18 digits (validated).
static # `WithCheckDigit(string digits)`	`string`	Digits with their GS1 check digit appended.
