Exceptional Hardware ID in C#
Any personal computer has elements that have a specific serial amount. Some figures are assigned when the operating technique is set up, but some are essentially embedded in the hardware. Making use of C#, a number of embedded serials can be combined to generate a exceptional pc ID.
Why a unique serial? A basic cause is for branding application to a distinct personal computer. A probably inflexible licensing method, it can be quite effective based on how it is employed.
For this write-up we will use two serials, the tricky drive and the CPU. Both of those will be attained with the created-in C# course Procedure.Management.
If you create a New Venture in Visible Studio 2005 (any of the editions), you will observe the line “utilizing System.Administration” does not function. You have to increase it manually:
- Go to the Remedy Explorer
- Right-simply click on References and click on “Increase Reference…”
- Obtain Technique.Management from the .Net tab.
The moment established up it is effortless to get the components ID’s.
The tricky generate ID’s is dependent of course on the harddrive. Below is the pseudocode:
- Make a ManagementObject with the string “get32_logicaldisk.deviceid=[drive letter here]:”
- Obtain the serial with the index “VolumeSerialNumber”, for illustration disk[“VolumeSerialNumber”] the place disk is the ManagementObject
The CPU ID is truly fairly adaptable also. A lot of computer systems nowadays have extra than a person CPU. You use the first just one as in my example, or a number of ones:
- Produce a ManagementObject with the string “gain32_processor”
- Go by means of the out there processors
- Access the house like so: managObject.Houses[“processorID”]
Combining them can be straightforward or complicated. Merely including them jointly in a row operates just fantastic. For my case in point some redundant 0’s are taken off right before coming the ID’s of the to start with accessible travel and the to start with CPU.
Check out it out to see how the quantities look.
