A readonly struct for representing byte sizes with human-readable formatting, arithmetic operations, and full serialization support including dictionary key compatibility.
A high-performance, readonly struct for representing byte sizes with human-readable formatting, arithmetic operations, and full serialization support including dictionary key compatibility.
Features
Readonly struct - Immutable, thread-safe, and efficient
Human-readable formatting - Automatically formats as "1.5 KB", "2.3 MB", etc.
Full arithmetic support - Addition, subtraction, multiplication, division
Implicit conversions - Seamlessly convert between numeric types and Bytes
Parsing support - Parse strings like "1.5GB" or "2048"
JSON serialization - Full support including use as dictionary keys
DataContract support - XML/Binary serialization without ProtoBuf dependencies
Zero allocations - Optimized for performance
Cross-platform - Targets .NET 8.0 and .NET 9.0
Installation
dotnet add package ModelingEvolution.Bytes
Quick Start
using ModelingEvolution;
// Create from numeric values
Bytes size1 = 1024; // 1 KB
Bytes size2 = new Bytes(1536); // 1.5 KB
Bytes size3 = Bytes.FromFile("file.txt");
// Parse from strings
Bytes size4 = "2.5 GB"; // Implicit conversion
Bytes size5 = Bytes.Parse("100 MB");
// Arithmetic operations
var total = size1 + size2; // 2.5 KB
var difference = size2 - size1; // 512 bytes
var scaled = size1 * 4; // 4 KB
var divided = size2 / 2; // 768 bytes
// Display formatting
Console.WriteLine(size2); // "1.5 KB"
Console.WriteLine(size2.Value); // 1536 (raw bytes)
// Comparisons
if (size1 < size2)
Console.WriteLine("size1 is smaller");
// Use in collections
var dictionary = new Dictionary<Bytes, string>
{
[Bytes.Parse("1GB")] = "Large file",
[Bytes.Parse("1MB")] = "Small file"
};
JSON Serialization
The Bytes struct includes full JSON support with a custom converter that handles both regular serialization and dictionary key scenarios:
using System.Text.Json;
// Simple serialization
var bytes = new Bytes(1024);
var json = JsonSerializer.Serialize(bytes); // "1024"
var deserialized = JsonSerializer.Deserialize<Bytes>(json);
// As dictionary keys
var dict = new Dictionary<Bytes, string>
{
[new Bytes(1024)] = "Config",
[new Bytes(1048576)] = "Data"
};
var dictJson = JsonSerializer.Serialize(dict);
// {"1024":"Config","1048576":"Data"}
// Complex objects
public class FileInfo
{
public string Name { get; set; }
public Bytes Size { get; set; }
}
var file = new FileInfo { Name = "video.mp4", Size = "1.5GB" };
var fileJson = JsonSerializer.Serialize(file);
DataContract Serialization
Full support for WCF/XML serialization without ProtoBuf dependencies:
using System.Runtime.Serialization;
[DataContract]
public class Document
{
[DataMember]
public string Title { get; set; }
[DataMember]
public Bytes FileSize { get; set; }
}
// XML serialization works out of the box
var serializer = new DataContractSerializer(typeof(Document));
Parsing Formats
The parser supports various formats with case-insensitive suffixes:
