Soenneker.Extensions.Arrays.Bytes

UTF-8 decoding, hexadecimal and Base64 encoding, MemoryStream wrapping, and null/empty checks for byte arrays and read-only byte spans.

Installation

dotnet add package Soenneker.Extensions.Arrays.Bytes

Text and binary encodings

using System.Text;
using Soenneker.Extensions.Arrays.Bytes;

byte[] bytes = Encoding.UTF8.GetBytes("hello");

string text = bytes.ToStr();              // "hello"
string hex = bytes.ToHex();               // "68656C6C6F"
string lowerHex = bytes.ToHexLower();     // "68656c6c6f"
string base64 = bytes.ToBase64String();   // "aGVsbG8="

ToStr() decodes with .NET's default UTF-8 encoding behavior. Invalid byte sequences are replaced with the Unicode replacement character; this method does not reject malformed UTF-8. Use a strict UTF8Encoding instance when invalid input must fail.

ToHex() and ToHexLower() produce two characters per byte with no prefix or separators. ToBase64String() produces standard padded Base64, not Base64URL. Empty inputs produce an empty string. These methods encode data; they do not encrypt, hash, compress, authenticate, or hide it.

The UTF-8 and Base64 methods also have ReadOnlySpan<byte> overloads. Returned strings are allocations even when the source is a span.

Stream wrapping

byte[] buffer = [1, 2, 3];

using MemoryStream stream = buffer.ToStream();

ToStream() returns a writable, non-expandable stream backed by the original array with Position == 0. Writing within its existing length changes buffer; changing buffer is visible through the stream. Writing past capacity throws. Disposing the stream does not clear or dispose the byte array.

Copy the data first when the stream and caller must not share mutations:

using MemoryStream isolated = buffer.ToArray().ToStream();

Empty checks and nulls

byte[]? optional = null;
bool empty = optional.IsEmpty(); // true

IsEmpty() is the only nullable-array API and returns true for null or zero length. The conversion methods require a non-null receiver; a null array results in NullReferenceException.
