dotnetframework/Microsoft.Bcl.Memoryv9.0.2

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

<!-- The key features of this package -->

• 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

<!-- A compelling example on how to use this package with code, as well as any specific guidelines for when to use the package -->

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! <!-- The main types provided in this library --> <!-- Links to further documentation.
