What is iSMBIOS?

iSMBIOS is a lightweight implementation that allows us to obtain the SMBIOS information. Currently only works on Windows

This library implements DMTF Specification 3.7.0 version and olders versions

For more information, please see https://www.dmtf.org/standards/smbios

Install via NuGet

From nuget gallery

From package manager console

PM> Install-Package iSMBIOS

Install via PowerShell

Now if you want you can use iSMBIOS from PowerShell. It has the iPowerShellSmbios module available that contains a collection of Cmdlets that allow us to obtain the SMBIOS information. If you want to know more, please review the available documentation from here.

From PowerShellGallery

From PowerShell console

PM> Install-Module -Name iPowerShellSmbios

Usage

Before

Call DMI.Instance.Structures for getting all SMBIOS structures availables.

Now

The DMI.Instance property now is mark as obsolete use DMI.CreateInstance() method instead If you want to connect to a remote machine fill in an instance of the DmiConnectOptions object and use it as the argument of the DMI method.CreateInstance(optionsInstance).

For more info, please see CHANGELOG file.

Examples

Gets and prints SMBIOS version.

Console.WriteLine($@" SMBIOS Version > {DMI.CreateInstance().SmbiosVersion}");

Gets and prints all SMBIOS availables structures.

DmiStructureCollection structures = DMI.CreateInstance().Structures;
foreach (DmiStructure structure in structures)
{
    Console.WriteLine($@" {(int)structure.Class:D3}-{structure.FriendlyClassName}");

    int totalStructures = structure.Elements.Count;
    if (totalStructures > 1)
    {
        Console.WriteLine($@"     > {totalStructures} structures");
    }
}

Gets and prints the implemented SMBIOS structure version.

DmiStructureCollection structures = DMI.CreateInstance().Structures;
foreach (DmiStructure structure in structures)
{
    Console.WriteLine($@" {(int)structure.Class:D3}-{structure.FriendlyClassName}");

    DmiClassCollection elements = structure.Elements;
    foreach (DmiClass element in elements)
    {
        Console.WriteLine($@"     > Version > {element.ImplementedVersion}");
    }
}

Gets a single property directly.

DmiStructureCollection structures = DMI.CreateInstance().Structures;
QueryPropertyResult biosVersion = structures.GetProperty(DmiProperty.Bios.BiosVersion);
if (biosVersion.Success)
{
    Console.WriteLine($@" > BIOS Version > {biosVersion.Result.Value}");
}
 
QueryPropertyResult biosVendor = structures.GetProperty(DmiProperty.Bios.Vendor);
if (biosVendor.Success)
{
    Console.WriteLine($@" > BIOS Vendor > {biosVendor.Result.Value}");
}

QueryPropertyResult currentSpeed = structures.GetProperty(DmiProperty.Processor.CurrentSpeed);
if (currentSpeed.Success)
{
    Console.WriteLine($@" > Current Speed > {currentSpeed.Result.Value} {currentSpeed.Result.Key.PropertyUnit}");
}

QueryPropertyResult processorManufacturer = structures.GetProperty(DmiProperty.Processor.ProcessorManufacturer);
if (processorManufacturer.Success)
{
    Console.WriteLine($@" > Processor Manufacturer > {processorManufacturer.Result.Value}");
}

Gets a property in multiple elements directly (Handle result as collection).

// Requires that the Slot Information structure exists in your system
DmiStructureCollection structures = DMI.CreateInstance().Structures;
QueryPropertyCollectionResult systemSlotsQueryResult = structures.GetProperties(DmiProperty.SystemSlots.SlotDesignation);
if (!systemSlotsQueryResult.Success)
{
    Console.WriteLine($@" > Error(s)");
    Console.WriteLine($@"   {systemSlotsQueryResult.Errors.AsMessages().ToStringBuilder()}");
}
else
{
    IEnumerable<PropertyItem> systemSlotsItems = systemSlotsQueryResult.Result.ToList();
    bool hasSystemSlotsItems = systemSlotsItems.Any();
    if (!hasSystemSlotsItems)
    {
        Console.WriteLine($@" > Sorry, The '{DmiProperty.SystemSlots.SlotId}' property has not implemented on this system");
    }
    else
    {
        int index = 0;
        foreach (var systemSlotItem in systemSlotsItems)
        {
            Console.WriteLine($@" >  System Slot ({index}) > {systemSlotItem.Value}");
            index++;
        }
    }
}

Gets a property in multiple elements directly (Handle result as dictionary).

 // Requires that the Slot Information structure exists in your system
 DmiStructureCollection structures = DMI.CreateInstance().Structures;
 QueryPropertyCollectionResult systemSlotsQueryResult = structures.GetProperties(DmiProperty.SystemSlots.SlotDesignation);
 var systemSlotsQueryDictionayResult = systemSlotsQueryResult.AsDictionaryResult();
 if (!systemSlotsQueryDictionayResult.Success)
 {
     Console.WriteLine($@" > Error(s)");
     Console.WriteLine($@"   {systemSlotsQueryDictionayResult.Errors.AsMessages().ToStringBuilder()}");
 }
 else
 {
     var systemSlotsItems = systemSlotsQueryDictionayResult.Result.ToList();
     bool hasSystemSlotsItems = systemSlotsItems.Any();
     if (!hasSystemSlotsItems)
     {
         Console.WriteLine($@" > Sorry, The '{DmiProperty.SystemSlots.SlotId}' property has not implemented on this system");
     }
     else
     {
         foreach (var systemSlotItemEntry in systemSlotsItems)
         {
             var itemIndex = systemSlotItemEntry.Key;
             var itemValue = systemSlotItemEntry.Value;
             Console.WriteLine($@" >  System Slot ({itemIndex}) > {itemValue.Value}");
         }
     }
 }

Prints all SMBIOS structures properties

     DmiClassCollection elements = structure.Elements;
     foreach (DmiClass element in elements)

How can I send feedback!!!

If you have found iSMBIOS useful at work or in a personal project, I would love to hear about it. If you have decided not to use iSMBIOS, please send me and email stating why this is so. I will use this feedback to improve iSMBIOS in future releases.
