iSMBIOS 1.0.3

What is iSMBIOS?

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

Usage

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

Examples

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;
   DeviceProperty<string> biosVersion = (DeviceProperty<string>)structures.GetProperty(KnownDmiProperty.Bios.BiosVersion);
   if (biosVersion != null)
   {
       Console.WriteLine($" BIOS Version > {biosVersion.Value}");
   }
   
   DeviceProperty<string> processorFamily = (DeviceProperty<string>)structures.GetProperty(KnownDmiProperty.Processor.Family);
   if (processorFamily != null)
   {
       Console.WriteLine($" CPU Family > {processorFamily.Value}");
   }
   
   DeviceProperty<string> processorManufacturer = (DeviceProperty<string>)structures.GetProperty(KnownDmiProperty.Processor.ProcessorManufacturer);
   if (processorManufacturer != null)
   {
       Console.WriteLine($" CPU Manufacturer > {processorManufacturer.Value}");
   }
   

4. Gets a property in multiple elements directly.

   DmiStructureCollection structures = DMI.Instance.Structures;
   IDictionary<int, IDeviceProperty> systemSlots = structures.GetProperties(KnownDmiProperty.SystemSlots.SlotId);
   foreach (KeyValuePair<int, IDeviceProperty> systemSlot in systemSlots)
   {
       int element = systemSlot.Key;
       DeviceProperty<string> property = (DeviceProperty<string>) systemSlot.Value;
       Console.WriteLine($" System Slot Id ({element}) > {property.Value}");
   }
   

5. Prints all SMBIOS structures properties

   foreach (DmiStructure structure in structures)
   {
       Console.WriteLine();
       Console.WriteLine(@" ——————————————————————————————————————————————————————————————");
       Console.WriteLine($@" {(int)structure.Class:D3}-{structure.Class} 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}");
                   }
               }
               else

           }
       }
   }
   

Changes

• v1.0.3 (This Version)

  • Added support for Type 43 [TPM Device].
  • Added native interop functions for handle the firmware tables.
  • Now first we try to get the BIOS data through a native call, if this fails, the call will be made through WMI.
  • Added two new methods to DmiStructureCollection class that allow you to consult a property directly. For more information, please see GetProperty and GetProperties.
  • Minor changes.

• v1.0.2

  • Update Structure Type 42, Minor changes
