iSMBIOS 1.1.3

What is iSMBIOS?

iSMBIOS is a lightweight implementation that allows us to obtain the SMBIOS information

This library implements DMTF Specification 3.4.0a (Preliminary version) and olders versions

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

Usage

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

Examples

1. Gets and prints SMBIOS version.

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

2. Gets and prints all SMBIOS availables structures.

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

5. Gets a single property directly.

   DmiStructureCollection structures = DMI.Instance.Structures;
   object biosVersion = structures.GetProperty(DmiProperty.Bios.BiosVersion);
   if (biosVersion != null)
   {
       Console.WriteLine($@" BIOS Version > {biosVersion}");
   }
   
   string biosVendor = structures.GetProperty<string>(DmiProperty.Bios.Vendor);
   Console.WriteLine($@" > BIOS Vendor > {biosVendor}");
   

6. Prints all SMBIOS structures properties

    DmiStructureCollection structures = DMI.Instance.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(@" ——————————————————————————————————————————————————————————————");
            DmiClassPropertiesTable elementProperties = element.Properties;
            foreach (KeyValuePair<IPropertyKey, object> property in elementProperties)
            {
                object value = property.Value;
   
                IPropertyKey key = property.Key;
                string friendlyName = GetFriendlyName(key);
                PropertyUnit valueUnit = key.PropertyUnit;
                string unit =
                    valueUnit == PropertyUnit.None
                        ? string.Empty
                        : valueUnit.ToString();
