How to retrieve hardware info in c#?

Question

I want to export the result of command 'wmic bios get' to a xml file. How can I read these data and add each data as a xml node?

@andyb952 I found only how to execute batch file and get result of that — cj__, Jul 17 '19 at 15:21
@cj__ if you found how to execute a batch file and how to get the result, why don't you try executing the command as batch file, getting the results and maybe wrap it up with some kind of [XmlWriter](https://learn.microsoft.com/en-us/dotnet/api/system.xml.xmlwriter?view=netframework-4.8)r? — FeRaaC, Jul 17 '19 at 15:24
@FeRaaC Because I need to retrieve hw data of the server from client side — cj__, Jul 17 '19 at 15:28

Something that actually had to do some time ago First you need class to handle requests by using wmi :

public class GetHW
    {
        public string identifier(string wmiClass, string wmiProperty, string wmiMustBeTrue)
        {
            string result = "";
            System.Management.ManagementClass mc = new System.Management.ManagementClass(wmiClass);
            System.Management.ManagementObjectCollection moc = mc.GetInstances();
            foreach (System.Management.ManagementObject mo in moc)
            {
                if (mo[wmiMustBeTrue].ToString() == "True")
                {
                    //Only get the first one
                    if (result == "")
                    {
                        try
                        {
                            result = mo[wmiProperty].ToString();
                            break;
                        }
                        catch
                        {
                        }
                    }
                }
            }
            return result;
        }

       public string identifier(string wmiClass, string wmiProperty)
        {
            string result = "";
            System.Management.ManagementClass mc = new System.Management.ManagementClass(wmiClass);
            System.Management.ManagementObjectCollection moc = mc.GetInstances();
            foreach (System.Management.ManagementObject mo in moc)
            {
                //Only get the first one
                if (result == "")
                {
                    try
                    {
                        result = mo[wmiProperty].ToString();
                        break;
                    }
                    catch
                    {
                    }
                }
            }
            return result;
        }
    }

Then in your actual application query class like this :

GetHW HW = new GetHW();
Dictionary <string, string> data = new Dictionary<string,string();
data.Add("Manufacturer", HW.identifier("Win32_BIOS", "Manufacturer"));
data.Add("SMBIOSBIOSVersion", HW.identifier("Win32_BIOS", "SMBIOSBIOSVersion"));
data.Add("IdentificationCode", HW.identifier("Win32_BIOS", "IdentificationCode"));
data.Add("SerialNumber", HW.identifier("Win32_BIOS", "SerialNumber"));
data.Add("ReleaseDate", HW.identifier("Win32_BIOS", "ReleaseDate"));
data.Add("Version", HW.identifier("Win32_BIOS", "Version"));

Then do whatever you want with dictionary. It might be overkill for bios data, but it will allow you to pull other data if you ever need to - e.g. motherboard :

data.Add("Model", HW.identifier("Win32_BaseBoard", "Model"));
data.Add("Manufacturer", HW.identifier("Win32_BaseBoard", "Manufacturer"));
data.Add("Name", HW.identifier("Win32_BaseBoard", "Name"));
data.Add("SerialNumber", HW.identifier("Win32_BaseBoard", "SerialNumber"));

or CPU

data.Add("Unique ID", HW.identifier("Win32_Processor", "UniqueId")); 
data.Add("ID", HW.identifier("Win32_Processor", "ProcessorId"));
data.Add("Name", HW.identifier("Win32_Processor", "Name"));
data.Add("Manufacturer", HW.identifier("Win32_Processor", "Manufacturer"));
data.Add("MaxClockSpeed", HW.identifier("Win32_Processor", "MaxClockSpeed"));

Edit : In case anyone ever need to - here is a a list of all win32 classes.

Take a look at http://codemaverick.blogspot.com/2007/02/how-to-retrieve-management-information.html solution. The queries you might want to run are mosQuery = "SELECT * FROM Win32_DiskDrive"; and mosQuery = "SELECT * FROM Win32_DiskPartition"; — Vytautas Plečkaitis, Jul 17 '19 at 15:49
