How to identify the hardware details of a Linux/Mac machine using .Net Core

Question

How to identify the hardware details of a Linux/Mac machine using.Net Core.

For windows machines, we can use System.Management and WMI Query.

So is there any similar way to identify the hardware details (like RAM ,Processor,Monitor ,CAM etc) of Linux and Mac machines.

For windows, I'm using:

ManagementObjectSearcher searcher = 
    new ManagementObjectSearcher("select * from Win32_Processor");

Answer 1

I have done a workaround to get hardware info as per Platform. For windows I have used old way of system Management classes, for Linux i have used different Bash commands to Get Processor Id, Model,model version,machine id. Following are some linux commands i am using

1. "LinuxModel": "cat /sys/class/dmi/id/product_name"
2. "LinuxModelVersion": "cat /sys/class/dmi/id/product_version"
3. "LinuxProcessorId": "dmidecode -t processor | grep -E ID | sed 's/.*: //' | head -n 1"
4. "LinuxFirmwareVersion": "cat /sys/class/dmi/id/bios_version",
5. "LinuxMachineId": "cat /var/lib/dbus/machine-id"

Waiting for some support in the .net core framework soon

I have also used similar extension method with a bit optimized code for bash command

public static string Bash(this string cmd)
        {
            string result = String.Empty;

            try
            {
                var escapedArgs = cmd.Replace("\"", "\\\"");

                using (Process process = new Process())
                {
                    process.StartInfo = new ProcessStartInfo
                    {
                        FileName = "/bin/bash",
                        Arguments = $"-c \"{escapedArgs}\"",
                        RedirectStandardOutput = true,
                        UseShellExecute = false,
                        CreateNoWindow = true,
                    };

                    process.Start();
                    result = process.StandardOutput.ReadToEnd();
                    process.WaitForExit(1500);
                    process.Kill();
                };
            }
            catch (Exception ex)
            {
                //Logger.ErrorFormat(ex.Message, ex);
            }
            return result;
        }

Answer 2

This is a piece of code to write bash linux commends in .net core:

using System;
using System.Diagnostics;
    public static class ShellHelper
    {
        public static string Bash(this string cmd)
        {
            var escapedArgs = cmd.Replace("\"", "\\\"");

            var process = new Process()
            {
                StartInfo = new ProcessStartInfo
                {
                    FileName = "/bin/bash",
                    Arguments = $"-c \"{escapedArgs}\"",
                    RedirectStandardOutput = true,
                    UseShellExecute = false,
                    CreateNoWindow = true,
                }
            };
            process.Start();
            string result = process.StandardOutput.ReadToEnd();
            process.WaitForExit();
            return result;
        }
    }

This is an extension method, you use it like this:

var output = "ps aux".Bash();

As for the commends, refer the Get Linux System and Hardware Details on the Command Line article on VITUX to help you out writing the commends, it lists most of the commends to collect system information on Linux.

For MAC:

System.Management.ManagementClass mc = default(System.Management.ManagementClass);
ManagementObject mo = default(ManagementObject);
mc = new ManagementClass("Win32_NetworkAdapterConfiguration");

ManagementObjectCollection moc = mc.GetInstances();
    foreach (var mo in moc) {
        if (mo.Item("IPEnabled") == true) {
              Adapter.Items.Add("MAC " + mo.Item("MacAddress").ToString());
         }
     }
