Operating system info and processor info in c#

Hi…

In this blog I will tell you that how to display operating system info and processor info by using c#. We can take help of WMI classes to display information of processor as well as to display information of operating system. There is another way to perform this task which is more efficient than WMI classes that is by using Registry editor. We know that Registry editor contains all information of system as well processor in their database. Then we can use registry editor to retrieve these values.

In this blog I will use concept, Registry as well as use WMI class. I will use Registry editor to display processor information and use WMI classes to display operating system information. Here is sample program which will complete out task..

Program to display operating system and processor info

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Management;   //This namespace is used to work with WMI classes. For using this namespace add reference of System.Management.dll .

using Microsoft.Win32;     //This namespace is used to work with Registry editor.

namespace OperatingSystemInfo1

{

    class TestProgram

    {

        static void Main(string[] args)

        {

            SystemInfo si = new SystemInfo();       //Create an object of SystemInfo class.

            si.getOperatingSystemInfo();            //Call get operating system info method which will display operating system information.

            si.getProcessorInfo();                  //Call get  processor info method which will display processor info.

            Console.ReadLine();                     //Wait for user to accept input key.

        }

    }

    public class SystemInfo

    {

        public void getOperatingSystemInfo()

        {

            Console.WriteLine("Displaying operating system info....\n");

            //Create an object of ManagementObjectSearcher class and pass query as parameter.

            ManagementObjectSearcher mos = new ManagementObjectSearcher("select * from Win32_OperatingSystem");

            foreach (ManagementObject managementObject in mos.Get())

            {

                if (managementObject["Caption"] != null)

                {

                    Console.WriteLine("Operating System Name  :  " + managementObject["Caption"].ToString());   //Display operating system caption

                }

                if (managementObject["OSArchitecture"] != null)

                {

                    Console.WriteLine("Operating System Architecture  :  " + managementObject["OSArchitecture"].ToString());   //Display operating system architecture.

                }

                if (managementObject["CSDVersion"] != null)

                {

                    Console.WriteLine("Operating System Service Pack   :  " + managementObject["CSDVersion"].ToString());     //Display operating system version.

                }

            }

        }

        public void getProcessorInfo()

        {

            Console.WriteLine("\n\nDisplaying Processor Name....");

            RegistryKey processor_name = Registry.LocalMachine.OpenSubKey(@"Hardware\Description\System\CentralProcessor\0", RegistryKeyPermissionCheck.ReadSubTree);   //This registry entry contains entry for processor info.

            if (processor_name != null)

            {

                if (processor_name.GetValue("ProcessorNameString") != null)

                {

                    Console.WriteLine(processor_name.GetValue("ProcessorNameString"));   //Display processor ingo.

                }

            }

        }

    }

}

Output of following code snippet is as follows

Displaying operating system info....

Operating System Name  :  Microsoft Windows 7 Ultimate

Operating System Architecture  :  64-bit

Operating System Service Pack   :  Service Pack 1

Displaying Processor Name....

Intel(R) Core(TM)2 Duo CPU     E7500  @ 2.93GHz
