C# Array Properties and Class Structure

Question

The current structure of my classes goes a little bit like this: PC.Processor.Architecture[0] = The Architecture of the first processor (assuming a multi-processor system).

How I ideally want it is more like this: PC.Processor[0].Architecture, because it's a bit more self explanatory this way.

Is there a fairly efficient way of doing this with what I have? Bear in mind there are like, over 9000 properties in each of the classes Processor, Motherboard, Memory etc and WMI calls are not CPU-cheap to run.

Here are the important snippets for my classes

class PC
{
    public Processor Processor;
    public Motherboard Motherboard;

    // Constructor
    public PC()
    {
        Processor = new Processor();
        Motherboard = new Motherboard();
    }

    // Method to get all info sequentially
    public void GetAllInfo()
    {
        Processor.GetInfo();
        Motherboard.GetInfo();
    }
}

class Processor
{
    public string[] Architecture;
    public string[] Availability;
    public UInt16[] Cores;

    public void GetInfo()
    {
        // Get WMI Information from custom process
        // Returns as an array of ManagementObjects for each matched device (which is a bit like an array of dictionaries)
        ManagementObject[] WMIData = DataRetriever.GetWMIData("Win32_Processor");
        try
        {
            for (int i = 1; i < WMIData.Length; i++)
            {
                this.Architecture[i] = (string)WMIData[i]["Architecture"];
                this.Availability[i] = (string)WMIData[i]["Availability"];
                this.Cores[i] = (UInt16)WMIData[i]["NumberOfCores"];
            }
        }
        catch (NullReferenceException e)
        {
            // To be implemented
        }
    }
}

FURTHERMORE
There may be more than one WMI search query per class. For example, HardDrive needs to make use of both Win32_PhysicalMedia and ATAPI_SmartData (or whatever the class actually is.)

Answer 1

Thanks to everyone who's responded. I've come up with a reasonably elegant solution that suits my needs.

PC Class Example:

public class PC
{
    public List<Processor> Processor;

    // Constructor
    public PC()
    {
        this.Processor = new List<Processor>();
    }

    // Method to get all info sequentially
    public void GetAllInfo()
    {
        // These temporary stores fetch WMI data as ManagementObjects
        // Most cases will only need one WMI class.
        ManagementObject[] WMIDataTemp1;
        ManagementObject[] WMIDataTemp2;

        WMIDataTemp1 = DataRetriever.GetWMIData("Win32_Processor");
        foreach (ManagementObject Object in WMIDataTemp1)
        {
            this.Processor.Add(new Processor(Object));
        }
    }

    public void RefreshAll()
    {
        // Delete the lists and start again
        // Another option would be to foreach through the list elements and initialise each object again.
        this.Processor.Clear();
        GetAllInfo();
    }

    public void RefreshVolatileData()
    {
        // Extra function that will do some cool stuff later.
    }
}

Processor Class Example:

public class Processor
{
    // Define properties
    public string Architecture = "N/A";
    public string Availability = "N/A";
    public UInt32 CacheL2 = 0;
    public UInt32 CacheL3 = 0;

    // Overloaded constructor method
    // The one with no arguments does nothing to initialise the class
    // The one with the ManagementObject argument will call GetInfo to arrange the held data into the properties above
    public Processor() { }
    public Processor(ManagementObject wmiProcessor)
    {
        this.GetInfo(wmiProcessor);
    }

    // The main information handler for the classes.
    // This splits out the data in the ManagementObject into the class's own properties
    public void GetInfo(ManagementObject wmiProcessor)
    {
        // If anything fails, the try loop will just end without making a fuss
        // Because of the default values, N/A will be displayed everywhere if something fails here.
        try
        {
            this.Architecture = (string)wmiProcessor["Architecture"];
            this.Availability = (string)wmiProcessor["Availability"];
            this.CacheL2 = (UInt32)wmiProcessor["L2CacheSize"];
            this.CacheL3 = (UInt32)wmiProcessor["L3CacheSize"];
        }
        catch (Exception e)
        {

        }
    }
}

Usage example:

public PC Computer = new PC();
Computer.GetAllInfo();
textbox1.Text = Computer.Processor[0].Architecture

In the event a device needs to query more than one WMI class, each additional class can be listed as an extra parameter in the device constructor and GetInfo() method.
