A lightweight, high-performance, and safe .NET library to natively read SMBIOS (System Management BIOS) and DMI tables on Windows environments without external runtime overhead.
- Zero WMI Dependencies: Avoids slow, heavy, or enterprise-blocked Windows Management Instrumentation (WMI) queries.
- Direct Low-Level Access: Safely invokes native Win32 APIs (
GetSystemFirmwareTable) underneath. - Enterprise Asset Auditing: Ideal for hardware fingerprinting, hardware binding, anti-piracy, and asset tracking.
- DMTF Compliant: Full compliance with the Distributed Management Task Force (DMTF) standards (up to SMBIOS v3.7.0).
Install via NuGet Package Manager Console:
Install-Package iSMBIOSOr via .NET CLI:
dotnet add package iSMBIOSHere is how to solve the most common hardware identification tasks instantly.
using iSMBIOS;
using System;
using System.Linq;
class Program
{
static void Main()
{
var dmi = DMI.CreateInstance();
var baseBoard = dmi.BaseBoard.FirstOrDefault();
if (baseBoard != null)
{
Console.WriteLine($"Manufacturer: {baseBoard.Manufacturer}");
Console.WriteLine($"Product/Model: {baseBoard.Product}");
Console.WriteLine($"Serial Number: {baseBoard.SerialNumber}");
Console.WriteLine($"Version: {baseBoard.Version}");
}
}
}using iSMBIOS;
using System;
using System.Linq;
class Program
{
static void Main()
{
var dmi = DMI.CreateInstance();
// Extract Unique System UUID
var systemInfo = dmi.System.FirstOrDefault();
if (systemInfo != null)
{
Console.WriteLine($"System UUID: {systemInfo.Uuid}");
Console.WriteLine($"SKU Number: {systemInfo.SkuNumber}");
}
// Extract BIOS Firmware details
var biosInfo = dmi.Bios.FirstOrDefault();
if (biosInfo != null)
{
Console.WriteLine($"BIOS Vendor: {biosInfo.Vendor}");
Console.WriteLine($"BIOS Version: {biosInfo.BiosVersion}");
Console.WriteLine($"Release Date: {biosInfo.BiosReleaseDate}");
}
}
}For complex architectures requiring granular metadata extraction, iSMBIOS exposes a powerful underlying query engine to safely read typed collections, raw structural data, or custom tables.
You can quickly identify the exact operational firmware specification implemented on the host machine:
using iSMBIOS;
using System;
class Program
{
static void Main()
{
// Gets and prints the global SMBIOS specification version
Console.WriteLine($"SMBIOS Version > {DMI.CreateInstance().SmbiosVersion}");
// Gets and prints the specific implemented structure version
Console.WriteLine($"Implemented Version > {DMI.CreateInstance().ImplementedVersion}");
}
}To fetch individual data keys programmatically without iterating collections manually:
using iSMBIOS;
using System;
class Program
{
static void Main()
{
var dmi = DMI.CreateInstance();
// Fetch a single property via strong-typed key definitions
var result = dmi.GetProperty(SmbiosStructure.Bios, BiosProperty.BiosVersion);
Console.WriteLine($"Property Description: {result.Property.Description}");
Console.WriteLine($"Raw Value: {result.Value}");
}
}When dealing with complex multiple-element arrays (like multi-channel RAM layouts or multi-socket CPUs):
using iSMBIOS;
using System;
class Program
{
static void Main()
{
var dmi = DMI.CreateInstance();
// Approach A: Handle results as an enumerable collection
var collectionResult = dmi.GetCollectionProperties(SmbiosStructure.BaseBoard);
// Approach B: Handle results mapped cleanly into a queryable data dictionary
var dictionaryResult = dmi.GetDictionaryProperties(SmbiosStructure.Processor);
}
}For deeply customized firmware definitions or low-level diagnostic logs:
using iSMBIOS;
using System;
class Program
{
static void Main()
{
var dmi = DMI.CreateInstance();
// Print raw structure types, handles, and binary lengths available in memory
foreach (var structure in dmi.Structures)
{
Console.WriteLine($"Type: {structure.Header.Type} | Handle: {structure.Header.Handle} | Length: {structure.Header.Length}");
}
}
}Looking for a scriptable, infrastructure-wide deployment? We also maintain iPowerShellSmbios, which wraps this entire engine into native Cmdlets. It allows System Administrators and DevOps engineers to seamlessly run hardware inventories across data centers or target clusters in active server management.
