Hi, I need to generate a random number that won't change when I restart the program, but is different on every PC.
Will this help?

Something like
[csharp]System.Random pnrg = new System.Random(System.Environment.MachineName.GetHashCode());[/csharp]
Though then the numbers can easily be changed by changing the computers name.
Could be enough for your purpose though?

Actually, when you want it to run on Mono, then you cannot use System.Management.
You could consider using a hash based on the MAC address of the first physical network adapter or even multiple physical adapters.
Issues & merits & other shit:
- Not guaranteed to be unique, but will most likely be unique.
- Only use physical adapters as virtual adapters can be added / removed at run-time. (VM ware host adapters, etc.)
- Include disabled adapters, otherwise enabling / disabling an adapter would change the hash.
- Will persist even with a hard drive change.
- Sort the adapters by MAC address so that the order is always the same.
