Haukcode.Network 1.1.30

Haukcode.Network

A .NET library providing common network utilities and efficient binary I/O operations for network programming.

Quick Start

Installation

dotnet add package Haukcode.Network

Features

• Network Adapter Discovery - Query network interfaces, IP addresses, and MAC addresses
• Binary I/O - Efficient big-endian and little-endian binary readers/writers
• Network Utilities - Multicast addresses, broadcast addresses, socket configuration

Usage Examples

Get Network Adapters

using Haukcode.Network;

// Get first available IP address
var (ipAddress, netMask, macAddress) = Utils.GetFirstBindAddress();

// Get all adapters
var adapters = Utils.GetCommonAdapters();
foreach (var adapter in adapters)
{
    Console.WriteLine($"{adapter.DisplayName}: {adapter.AllIpv4Addresses[0].IP}");
}

Binary I/O (Network Byte Order)

using Haukcode.Network;

// Write binary data
var buffer = new byte[1024];
var writer = new BigEndianBinaryWriter(buffer);
writer.WriteUInt16(0x1234);
writer.WriteUInt32(0x12345678);
writer.WriteString("Hello", 10);

// Read binary data
var reader = new BigEndianBinaryReader(buffer);
ushort value16 = reader.ReadUInt16();
uint value32 = reader.ReadUInt32();
string text = reader.ReadString(10);

Network Utilities

using Haukcode.Network;
using System.Net;

// Generate multicast address
IPAddress multicast = Utils.GetMulticastAddress(1); // 239.255.0.1

// Calculate broadcast address
IPAddress broadcast = Utils.GetBroadcastAddress(
    IPAddress.Parse("192.168.1.100"),
    IPAddress.Parse("255.255.255.0")); // 192.168.1.255

// Configure socket
var socket = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp);
Utils.SetSocketOptions(socket);

Key APIs

Network Utilities:

• Utils.GetCommonAdapters() - Get ethernet and WiFi adapters
• Utils.GetFirstBindAddress() - Get first available IP address
• Utils.GetMulticastAddress(universeId) - Generate multicast address
• Utils.GetBroadcastAddress(ip, netmask) - Calculate broadcast address
• Utils.SetSocketOptions(socket) - Configure socket options

Binary I/O:

• BigEndianBinaryReader / BigEndianBinaryWriter - Network byte order
• LittleEndianBinaryReader / LittleEndianBinaryWriter - Little-endian
• Supports: Int16, UInt16, Int32, UInt32, bytes, strings, GUIDs
• Memory-efficient with Memory<T> and Span<T>
