Battery, BIOS, CPU - processor, storage drive, keyboard, RAM - memory, monitor, motherboard, mouse, NIC - network adapter, printer, sound card - audio card, graphics card - video card. Hardware.Info is a .NET Standard 2.0 library and uses WMI on Windows, /dev, /proc, /sys on Linux and sysctl, system_profiler on macOS.

How to use:

  1. Include NuGet package from https://www.nuget.org/packages/Hardware.Info

         <PackageReference Include="Hardware.Info" Version="" />
  2. Call RefreshAll() or one of the other Refresh*() methods:

     class Program
         static readonly IHardwareInfo hardwareInfo = new HardwareInfo();
         static void Main(string[] _)
             foreach (var hardware in hardwareInfo.BatteryList)
             foreach (var hardware in hardwareInfo.BiosList)
             foreach (var cpu in hardwareInfo.CpuList)
                 foreach (var cpuCore in cpu.CpuCoreList)
             foreach (var drive in hardwareInfo.DriveList)
                 foreach (var partition in drive.PartitionList)
                     foreach (var volume in partition.VolumeList)
             foreach (var hardware in hardwareInfo.KeyboardList)
             foreach (var hardware in hardwareInfo.MemoryList)
             foreach (var hardware in hardwareInfo.MonitorList)
             foreach (var hardware in hardwareInfo.MotherboardList)

             foreach (var hardware in hardwareInfo.PrinterList)
             foreach (var hardware in hardwareInfo.SoundDeviceList)
             foreach (var hardware in hardwareInfo.VideoControllerList)
             foreach (var address in HardwareInfo.GetLocalIPv4Addresses(NetworkInterfaceType.Ethernet, OperationalStatus.Up))
             foreach (var address in HardwareInfo.GetLocalIPv4Addresses(NetworkInterfaceType.Wireless80211))
             foreach (var address in HardwareInfo.GetLocalIPv4Addresses(OperationalStatus.Up))
             foreach (var address in HardwareInfo.GetLocalIPv4Addresses())

Known issues

21 second delay on first use in Windows

Hardware.Info uses WMI (Windows Management Instrumentation) on Windows OS. For certain queries WMI takes 21 seconds to initialize the first time you use it, after that all subsequent queries will execute immediately. If WMI isn't used for 15 minutes it will have to be initialized again the next time you use it.

The 21 second initialization delay is caused by RPC that WMI uses internally. In RPC documentation it says that the RPC/TCP time-out interval is defined with a SCMApiConnectionParam registry value located at HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control and that the default value is set to 21,000 (21 seconds).

You can avoid the 21 second delay by excluding the queries that cause it (see Settings).

Invalid NetworkAdapter.Speed in Windows

Sometimes NetworkAdapter.Speed in Win32_NetworkAdapter can be 0 or long.MaxValue. The correct value can be retrived from CurrentBandwidth in Win32_PerfFormattedData_Tcpip_NetworkAdapter but unfortunately reading from Win32_PerfFormattedData_Tcpip_NetworkAdapter causes a 21 second delay on the first read, like mentioned in the previous paragraph. Calling RefreshNetworkAdapterList with includeBytesPersec = true will also read the CurrentBandwidth.

WmiNetUtilsHelper will throw an exception in Windows if publish settings use <PublishTrimmed>true</PublishTrimmed>

This is a known error: https://github.com/dotnet/core/issues/7051#issuecomment-1071484354


Constructor settings:

HardwareInfo(bool useAsteriskInWMI = true, TimeSpan? timeoutInWMI = null)

The construcotr accepts two settings for WMI:

  • useAsteriskInWMI causes WMI queries to use SELECT * FROM instead of SELECT with a list of property names. This is slower, but safer, more compatible with older Windows (XP, Vista, 7, 8) where a certain WMI property might be missing and throw an exception when queried by name. The default value is true.
  • timeoutInWMI sets the Timeout property of the EnumerationOptions in the ManagementObjectSearcher that executes the query. The default value is EnumerationOptions.InfiniteTimeout. Changing this could cause the query to return empty results in certain cases.

Refresh methods settings:

In these two methods you can exclude some slow queries by setting the parameters to false:

RefreshCPUList(bool includePercentProcessorTime = true)

RefreshNetworkAdapterList(bool includeBytesPersec = true, bool includeNetworkAdapterConfiguration = true)

Setting includePercentProcessorTime and includeBytesPersec to false will exclude the queries that:

  • cause a 21 second delay the first time they are called in Windows
  • cause a 1 second delay every time they are called in Linux

Setting includeNetworkAdapterConfiguration to false has only a small impact on performance.
