¯\_(ツ)_/¯ This involves Wmi and Classes although I am not entirely sure how to describe how it works or understand why I made it but I did...

Program.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Management;
using System.Text;
using System.Threading.Tasks;



namespace CompInfo
{
    class Program
    {
        static void Main(string[] args)
        {
            var BIOSCollection = WmiSearcher.GetWmiObject("Win32_BIOS");
            foreach(var BIOS in (ManagementObjectCollection)BIOSCollection) //Not the most optimal loop but it will do
            {
                WMI_Classes.Win32_BIOS BIOSInstance = new WMI_Classes.Win32_BIOS(BIOS);
                Console.WriteLine(BIOSInstance.Name); //Show the newly set value (set with real magic!)

            }
        }
    }
}

Win32_BIOS.cs

using System.Diagnostics;
using System.Management;

namespace CompInfo.WMI_Classes
{
    class Win32_BIOS
    {
    //I've simplified types to keep it easy to get the point across, in an ideal situation I'd make it convert to the rigth type. 
    //Aside from simplification these are all the properties found within Win32_BIOS (https://docs.microsoft.com/en-us/windows/desktop/cimwin32prov/win32-bios)
        public string BiosCharacteristics;
        public string BIOSVersion;
        public string BuildNumber;
        public string Caption;
        public string CodeSet;

        public string SystemBiosMajorVersion;
        public string SystemBiosMinorVersion;
        public string TargetOperatingSystem;
        public string Version;

        public Win32_BIOS(ManagementBaseObject Instance)
        {
            foreach(var WmiInstanceProperty in Instance.Properties)
            {
                foreach(var LocalProperty in this.GetType().GetFields())
                {
                    if(LocalProperty.Name == WmiInstanceProperty.Name) //Match up what we have in this class, to is from Win32_BIOS
                    {
                        if (WmiInstanceProperty.Value != null)
                        {
                            LocalProperty.SetValue(this, WmiInstanceProperty.Value.ToString()); //Set it in this class
                        }
                    }
                }
            }
        }
    }
}

WmiSearcher.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Management;

namespace CompInfo
{
    public static class WmiSearcher
    {
        public static object GetWmiObject(string WmiClass)
        {
            return new ManagementObjectSearcher($"SELECT * FROM {WmiClass}").Get(); //YOLO Get it all
        }
    }
}
