Example how to read SMBIOS Type 2 (Baseboard) and Type 8 (Port Connector) information:

using System;
using System.Linq;
using AlphaOmega.Debug;
using AlphaOmega.Debug.Native;
using AlphaOmega.Debug.Smb;

class Program
{
    static void Main(String[] args)
    {
        FirmwareT<FirmwareSmBios> fw = new FirmwareT<FirmwareSmBios>();
        FirmwareSmBios smbios = fw.GetData().Single();

        //Motherboard vendor and name
        Baseboard baseboard = smbios.GetType<Baseboard>();
        Console.WriteLine("Motherboard Manufacturer: {0} Name: {1}",baseboard.Manufacturer,baseboard.Product);

        //Try to find USB 3.0 (Not tested. It's a sample)
        foreach(TypeBase type in smbios.Types)
            switch(type.Header.Type)
            {
            case SmBios.Type.PortConnector:
                PortConnector type8 = (PortConnector)type;
                if(type8.Type.Port == SmBios.Type8.PortType.USB && type8.InternalReferenceDesignator.StartsWith("USB_3"))
                    Console.WriteLine("USB 3.0 port found");
            break;
            }
    }
}

Example how to save SMBIOS information:

FirmwareT<FirmwareSmBios> fw = new FirmwareT<FirmwareSmBios>();
System.IO.File.WriteAllBytes(@"C:\Temp\Firmware\smbios.sfw", fw.Save());

Example how to load SMBIOS infromation from file:

try{
    FirmwareT<FirmwareSmBios> smbios = new FirmwareT<FirmwareSmBios>(System.IO.File.ReadAllBytes(@"C:\Temp\Firmware\smbios.sfw"));
} catch(ArgumentNullException)//Empty file
{
    ...
} catch(ArgumentException)//Invalid signature or invalid firmware type (Ex. loading ACPI data)
{
...
}
