iSMBIOS 1.1.5

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 3.4.0 version and olders versions

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

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.

For more info, please see CHANGELOG

Examples

1. Gets and prints SMBIOS version.

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

2. 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");
       }
   }
   

3. 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}");
       }
   }
   

4. Gets a specific SMBIOS structure.

   DmiStructureCollection structures = DMI.CreateInstance().Structures;
   DmiStructure bios = structures[SmbiosStructure.Bios];
   if (bios != null)
   {
       /// structure exist!!!
   }
   

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

6. Prints all SMBIOS structures properties

    DmiStructureCollection structures = DMI.CreateInstance().Structures;      
    foreach (DmiStructure structure in structures)
    {
        DmiClassCollection elements = structure.Elements;
        foreach (DmiClass element in elements)
        {
            Console.WriteLine();
            Console.WriteLine(element.ImplementedVersion == DmiStructureVersion.Latest
                ? $@" ———————————————————————————————————————————————————— {element.ImplementedVersion} ——"
                : $@" ——————————————————————————————————————————————————————— {element.ImplementedVersion} ——");
            Console.WriteLine($@" {(int)structure.Class:D3}-{structure.FriendlyClassName} structure detail");
            Console.WriteLine(@" ——————————————————————————————————————————————————————————————");
   
            IEnumerable<IPropertyKey> properties = element.ImplementedProperties;
            foreach (var property in properties)
            {
                QueryPropertyResult queryResult = element.GetProperty(property);
