Get System Information in C#

In C#, we can get system information like Operation System , Processor Architecture and Drive Details using the built-in class Environment and we can also extract information through WMI service.

Get System Information using Environment

The below C# function get system information using Environment method.

public static void ShowSystemInformation()
{
    StringBuilder systemInfo = new StringBuilder(string.Empty);

    systemInfo.AppendFormat("Operation System:  {0}n", Environment.OSVersion);
    systemInfo.AppendFormat("Processor Architecture:  {0}n", Environment.GetEnvironmentVariable("PROCESSOR_ARCHITECTURE"));
    systemInfo.AppendFormat("Processor Model:  {0}n", Environment.GetEnvironmentVariable("PROCESSOR_IDENTIFIER"));
    systemInfo.AppendFormat("Processor Level:  {0}n", Environment.GetEnvironmentVariable("PROCESSOR_LEVEL"));
    systemInfo.AppendFormat("SystemDirectory:  {0}n", Environment.SystemDirectory);
    systemInfo.AppendFormat("ProcessorCount:  {0}n", Environment.ProcessorCount);
    systemInfo.AppendFormat("UserDomainName:  {0}n", Environment.UserDomainName);
    systemInfo.AppendFormat("UserName: {0}n", Environment.UserName);
    //Drives
    systemInfo.AppendFormat("LogicalDrives:n");
    foreach (System.IO.DriveInfo DriveInfo1 in System.IO.DriveInfo.GetDrives())
    {
        try
        {
            systemInfo.AppendFormat("t Drive: {0}ntt VolumeLabel: " +
                "{1}ntt DriveType: {2}ntt DriveFormat: {3}ntt " +
                "TotalSize: {4}ntt AvailableFreeSpace: {5}n",
                DriveInfo1.Name, DriveInfo1.VolumeLabel, DriveInfo1.DriveType,
                DriveInfo1.DriveFormat, DriveInfo1.TotalSize, DriveInfo1.AvailableFreeSpace);
        }
        catch
        {
        }
    }
    systemInfo.AppendFormat("Version:  {0}", Environment.Version);
    Console.WriteLine(systemInfo);
    Console.ReadKey();
}

Output:

Get System Information using WMI class in C#

The below C# function get system information using WMI class. You need to add reference

public static void SystemInformation()
{
    StringBuilder processorInfo = new StringBuilder(string.Empty);
    ManagementClass mgmntClass = new ManagementClass("Win32_OperatingSystem");
    ManagementObjectCollection mgmntObj = mgmntClass.GetInstances();
    PropertyDataCollection properties = mgmntClass.Properties;
    foreach (ManagementObject obj in mgmntObj)
    {
        foreach (PropertyData property in properties)
        {
            try
            {
                processorInfo.AppendLine(property.Name + ":  " +
                    obj.Properties[property.Name].Value.ToString());
            }
            catch
            {
            }
        }
        processorInfo.AppendLine();
    }
    Console.WriteLine(processorInfo);
    Console.ReadKey();
}
