How to read devices and driver versions

Question

I\'m having a really hard time figuring out how to do this. Basically, all I want to do is read all the devices that are attached to the machine and also read the driver man

Answer 1

Please have a look at the following article

Get Your Hardware Information Using C#

Retrieving Information From Windows Management Instrumentation

EDIT:

I believe that you are looking for the following Win32_PnPSignedDriver class

public class Program
{
    public static void Main()
    {
        ManagementObjectSearcher objSearcher = new ManagementObjectSearcher("Select * from Win32_PnPSignedDriver");

        ManagementObjectCollection objCollection = objSearcher.Get();

        foreach (ManagementObject obj in objCollection)
        {
            string info = String.Format("Device='{0}',Manufacturer='{1}',DriverVersion='{2}' ", obj["DeviceName"], obj["Manufacturer"], obj["DriverVersion"]);
            Console.Out.WriteLine(info);
        }

        Console.Write("\n\nAny key...");
        Console.ReadKey();
    }
}

Aslo, if you are going to work a lot on WMI you might as well use this tool, to avoid creating test applications.

If you are looking for a specific kind of device information (suppose only Bluetooth) from your machine - then "ManagementObjectSearcher" in c# is good enough. You just need to include
using System.Management;
put a condition search with it as following

 ManagementObjectSearcher mos =
                   new ManagementObjectSearcher(@"\root\cimv2", @"Select * From Win32_PnPEntity WHERE ClassGuid = '"+deviceGuid+"'");

here "deviceGuid" is the device class type(a guid value [same for all PCs]).
