Answer 1

Use the Microsoft.Win32.Registry / .RegistryKey classes.
Example:

using Microsoft.Win32;
...
//Where CardInformation is some data structure to hold the information.

public static IEnumerable<CardInformation> GetCardInformation()
{
    string cardsKeyAddress =  "\SYSTEM\CurrentControlSet\Control\Class\{4D36E972-E325-11CE-BFC1-08002BE10318}";
    RegistryKey cardsKey = Registry.LocalMachine.OpenSubKey(cardsKeyAddress);
    string[] cardNumbers = cardsKey.GetSubKeyNames();

    foreach(string n in cardNumbers)
        yield return LoadCardInformation(cardsKeyAddress+"\\"+n);
}
static CardInformation LoadCardInformation(string key)
{
    //Get whatever values from the key to return
    CardInfomation info = new CardInformation();
    info.Name = Registry.GetValue(key, "Name", "Unnamed");
    return info;
}
