.net - How to uniquely identify computer using C#?

Question

How to uniquely identify computer (mainboard) using C#(.Net/Mono, local application)?

Edition. We can identify mainboard in .Net using something like this (see Get Unique System Identifiers in C#):

using System.Management;
...
ManagementObjectSearcher searcher = new ManagementObjectSearcher("select * from Win32_MotherboardDevice");
...

But unfortunately Mono does not support System.Management. How to do it under Mono for Linux? - I don't know :(

Answer 1

Write a function that takes a few unique hardware parameters as input and generates a hash out of them.

For example, Windows activation looks at the following hardware characteristics:

• Display Adapter
• SCSI Adapter
• IDE Adapter (effectively the motherboard)
• Network Adapter (NIC) and its MAC Address
• RAM Amount Range (i.e., 0-64mb, 64-128mb, etc.)
• Processor Type
• Processor Serial Number
• Hard Drive Device
• Hard Drive Volume Serial Number (VSN)
• CD-ROM / CD-RW / DVD-ROM

You can pick up a few of them to generate your unique computer identifier.
