I would like to develop fast port scanner using .NET. Is the PcapDotNet library a good idea? How to implement that funtionality using this library? I checked their samples, but they do not contain such functionality.

Thank you in advance for any help.

Your question points out the glaring fact that you have no idea what a port scanner does or how it does it. If you can't answer both of these questions accurately and in great detail you have no hope of completing this project. If you can't explain it to us how are you going to explain it to a computer that's going to be a lot more picky out it?

Pcap.Net is a wrapper for the WinPcap library which is a library to capture network packages.

But there is no need to capture packages for a port scanner. A port scanner tries to connect to services and waits for replies. Capturing these connect packages and the replies does not make any sense. You should read about Port scanner - Wikipedia[^] first.

You might have a look at Simple TCP Port Scanner[^] here at CodeProject for a first start on port scanning with C#.

If you want to use a library have a look at GitHub - thomdixon/SaltwaterTaffy: An nmap wrapper library for .NET[^] which is a wrapper for the Nmap: the Network Mapper - Free Security Scanner[^] library.
