NaceLookup

O(1) NACE Rev. 2.1 code lookup for .NET.

Maps 651 class codes (sections A–V) to human-readable descriptions and section names. Backed by a dictionary indexed by NACE code — thread-safe, zero-allocation after initialization, no external dependencies.

Install

dotnet add package NaceLookup

Usage

using Nace;

// Basic lookup
var result = NaceLookup.Get("64.19");
// result.Code        → "64.19"
// result.Description → "Other monetary intermediation"
// result.Section     → "L"
// result.SectionName → "Financial and Insurance Activities"

// Try-pattern
if (NaceLookup.TryGet("62.10", out var nace))
    Console.WriteLine(nace.Description); // "Computer programming activities"

// Get all codes in a section
var fintech = NaceLookup.GetBySection("L");

// Returns null for unknown codes, never throws
var unknown = NaceLookup.Get("99.99"); // null

// Flexible input formats
NaceLookup.Get("6419");  // same as "64.19"
NaceLookup.Get("01.11"); // standard format

// Total number of codes
Console.WriteLine(NaceLookup.Count); // 651
