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

This library fully implements DMTF Specification 3.2.0 and olders versions

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

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

1. Gets and prints all SMBIOS availables structures.

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

2. Gets a specific SMBIOS structure.

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

3. 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}");
   
   string processorFamily = structures.GetProperty<string>(DmiProperty.Processor.Family);
   Console.WriteLine($" Processor Family > {processorFamily}");
   
   string processorManufacturer = structures.GetProperty<string>(DmiProperty.Processor.ProcessorManufacturer);
   Console.WriteLine($" Processor Manufacturer > {processorManufacturer}");
   

4. Gets a property in multiple elements directly.

   // Requires that the Slot Information structure exists in your system
   DmiStructureCollection structures = DMI.Instance.Structures;
   IDictionary<int, object> systemSlots = structures.GetProperties(DmiProperty.SystemSlots.SlotId);
   foreach (KeyValuePair<int, object> systemSlot in systemSlots)
   {
       int element = systemSlot.Key;
       object property = systemSlot.Value;
       Console.WriteLine($" System Slot ({element}) > {property}");
   }
   

5. Prints all SMBIOS structures properties

   DmiStructureCollection structures = DMI.Instance.Structures;
   foreach (DmiStructure structure in structures)
   {
       DmiStructureClass currentClass = structure.Class;
   
       Console.WriteLine();
       Console.WriteLine($" —————————————————————————————————————————— DMI ({DMI.AccessType}) —");
       Console.WriteLine($" {(int)currentClass:D3}-{currentClass} structure detail");
       Console.WriteLine($" ——————————————————————————————————————————————————————————————");
       DmiClassCollection elements = structure.Elements;
       foreach (DmiClass element in elements)
       {
           Hashtable elementProperties = element.Properties;
           foreach (DictionaryEntry property in elementProperties)
           {
               object value = property.Value;
   
               PropertyKey key = (PropertyKey)property.Key;
               Enum id = key.PropertyId;
   
               PropertyUnit valueUnit = key.PropertyUnit;
               string unit =
                   valueUnit == PropertyUnit.None
                       ? string.Empty
                       : valueUnit.ToString();
   
               if (value == null)
               {
                   Console.WriteLine($"{id} > NULL");
                   continue;
               }
   
               if (value is string)
               {
                   Console.WriteLine($"   > {id} > {value} {unit}");
               }
               else if (value is byte)
               {
                   Console.WriteLine($"   > {id} > {value}{unit} [{value:X2}h]");
               }
               else if (value is short)
               {
                   Console.WriteLine($"   > {id} > {value}{unit} [{value:X4}h]");
               }
               else if (value is ushort)
               {
                    Console.WriteLine($"   > {id} > {value}{unit} [{value:X4}h]");
               }
               else if (value is int)
               {
                   Console.WriteLine($"   > {id} > {value} {unit} [{value:X4}h]");
               }
               else if (value is uint)
               {
                   Console.WriteLine($"   > {id} > {value} {unit} [{value:X4}h]");
               }
               else if (value is long)
               {
                   Console.WriteLine($"   > {id} > {value} {unit} [{value:X8}h]");
               }
               else if (value is ulong)
               {
                   Console.WriteLine($"   > {id} > {value} {unit} [{value:X8}h]");
               }
               else if (value.GetType() == typeof(ReadOnlyCollection<byte>))
               {
                   Console.WriteLine($"   > {id} > {string.Join(", ", (ReadOnlyCollection<byte>)value)}");
               }
               else if (value.GetType() == typeof(ReadOnlyCollection<string>))
               {
                   Console.WriteLine($"   > {id}");
                   var collection = (ReadOnlyCollection<string>) value;
                   foreach (var entry in collection)
                   {
                       Console.WriteLine($"     > {entry} {unit}");
                   }
               }
               else
               {
                   Console.WriteLine($"   > {id} > {value} {unit}");
               }
           }
       }

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.
