The limitation of using sn of a flash drive is that not all usb flash drives have sn.

Id like to use USB Flash Drive as some sort of key that protects my software from unauthorized use. That is the software will only run if flash drive I issue to the user is inserted into any USB port on the PC.<br />
&nbsp;<br />
Is there any BIOS or firmware unique ID or date/time on any typical flash drive and which API can I use to read those?<br />
&nbsp;<br />
Thank you.

C# is an object-oriented programming language created in conjunction with Microsoft’s .NET framework. Compilation is usually done into the Microsoft Intermediate Language (MSIL), which is then JIT-compiled to native code (and cached) during execution in the Common Language Runtime (CLR).

The .NET Framework is not specific to any one programming language; rather, it includes a library of functions that allows developers to rapidly build applications. Several supported languages include C#, VB.NET, C++ or ASP.NET.
