AirlineCollection 1.0.0

• Light-weight
• Device-agnostic country data (Alternative to the .NET Framework RegionInfo data)
• Preloaded airline information wtih IATA 2-digit code, ICAO 3-digit code, and names.
• Airline code lookup and normalization
• Convenient static data collection with methods
• Fully customizable instance data collection (to add new data and to remove old data)
• IEnumerable implementation (can be used with LINQ)
• DI-friendly interface
• Unit Tested
• No external library dependencies
• No external calls

STATIC MEMBERS

Read-only data collection

.Contains(code)

string code = "AA";
bool valid = AirlineCollection.Contains(code);  // True

.Contains(code)

string lowerCased = "aa";
bool valid = AirlineCollection.Contains(lowerCased);  // True

.Contains(code)

int numericCode = 1;
bool valid = AirlineCollection.Contains(numericCode);  // True

.Normalize(code)

string iata2DigitCode = "aa";
string code = AirlineCollection.Normalize(iata2DigitCode);  // "AA"

.Normalize(code)

string icao3DigitCode = "aal";
string code = AirlineCollection.Normalize(icao3DigitCode);  // "AAL"

.Normalize(code)

int numericCode = 1;
string code = AirlineCollection.Normalize(numericCode);  // "001"

.Normalize(code)

string invalidCode = "xyz";
string code = AirlineCollection.Normalize(invalidCode);  // null

.Normalize(code)

int numericCode = 99999;
string code = AirlineCollection.Normalize(numericCode);  // null

.GetAirline(code)

string code = "AA";
var country = AirlineCollection.GetAirline(code);  // { "Iata2LetterCode":"AA", "Icao3LetterCode":"USA", "Prefix":"001", "IataName":"American Airlines Inc.", "IcaoName":"American Airlines", "Callsign":"American Airlines", "Name":"American Airlines" }

.GetCountry(code)

string invalidCode = "XYZ";
var airline = CountryCollection.GetAirline(code);  // null

INSTANCE MEMBERS

Customizable data collection (All instance members can be mocked in unit testing by implementing IAirlineCollection)

[code]

string code = "AA";
var airline = new AirlineCollection()[code];  // { "Iata2LetterCode":"AA", "Icao3LetterCode":"USA", "Prefix":"001", "IataName":"American Airlines Inc.", "IcaoName":"American Airlines", "Callsign":"American Airlines", "Name":"American Airlines" }

.Add(iata2LetterCode, icao3LetterCode, prefix)

.Add(iata2LetterCode, icao3LetterCode, prefix, iataName, icaoName, callSign, name)

var airlines = new AirlineCollection();
airlines.Add("XX", "XXX", "999");
airlines.Add("ZZ", "ZZZ", "000", "ZZ Airline", "ZZ Air LLC", "ZZA", "ZZ Air");

.Remove(code)

var code = "AA";
var airlines = new AirlineCollection();
airlines.Remove(code);
