About

Provides Index and Range types to simplify slicing operations on collections for .NET Framework and .NET Standard 2.0. Provides Base64Url for encoding data in a URL-safe manner on .NET Framework and .NET Standard.

This library is not necessary nor recommended when targeting versions of .NET that include the relevant support.

Key Features

  • Enables the use of Index and Range types on older .NET platforms.
  • Provides Base64Url encoding, decoding, and validation for URL-safe data processing on older .NET platforms.

How to Use

The Index and Range types simplify working with slices of arrays, strings, or other collections.

string[] words = ["The", "quick", "brown", "fox", "jumps", "over", "the", "lazy", "dog"];

// Use Index to reference the last element
Console.WriteLine(words[^1]);
// Output: "dog"

// Use Range to reference a slice
string[] phrase = words[1..4];
Console.WriteLine(string.Join(" ", phrase));
// Output: "quick brown fox"

Base64Url encoding is a URL-safe version of Base64, commonly used in web applications, such as JWT tokens.

using System.Buffers.Text;
using System.Text;

// Original data
byte[] data = Encoding.UTF8.GetBytes("Hello World!");

Span<byte> encoded = new byte[Base64Url.GetEncodedLength(data.Length)];
Base64Url.EncodeToUtf8(data, encoded, out int _, out int bytesWritten);

string encodedString = Base64Url.EncodeToString(data);  
Console.WriteLine($"Encoded: {encodedString}");
// Encoded: SGVsbG8gV29ybGQh

Span<byte> decoded = new byte[data.Length];
Base64Url.DecodeFromUtf8(encoded[..bytesWritten], decoded, out _, out bytesWritten);

string decodedString = Encoding.UTF8.GetString(decoded[..bytesWritten]);
Console.WriteLine($"Decoded: {decodedString}");
// Decoded: Hello World!

Main Types

The main types provided by this library are:

  • System.Index
  • System.Range
  • System.Buffers.Text.Base64Url
