I'm wondering if anyone has worked with the ngspice.dll ( mixed-level/mixed-signal circuit simulator) in .NET with C#, Is there any code demonstrates how it can be invoked? Any help would be appreciated.

If you can't find any docs perhaps you can add a reference in VS to the dll and then using Intellisense figure out what it has to offer.

It's not possible to add it as reference since its unmanaged dll, so the only way is to call its functions using platform invoke.
by the way the documentation exist but its in C++.

As I understand, this is a native shared library, not CLI, so you will need to use P/Invoke:
