Hardware.Info
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.

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).
Settings
Constructor settings:
HardwareInfo(bool useAsteriskInWMI = true, TimeSpan? timeoutInWMI = null)
The construcotr accepts two settings for WMI:
useAsteriskInWMI
causes WMI queries to useSELECT * FROM
instead ofSELECT
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 istrue
.timeoutInWMI
sets theTimeout
property of theEnumerationOptions
in theManagementObjectSearcher
that executes the query. The default value isEnumerationOptions.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.
