ProcessConnectionsLib

Simple Library to expose network connections (TCP/UDP) per process, can be searchable by process id or process name. you can initialize the connections tables when you create instance of ProcessConnection class or overwrite the tables using initializeTables() function.

Usage:

using ProcessConnectionsLib;
using System;

namespace ConsoleTest
{
    class Program
    {
        static void Main(string[] args)
        {
            int pid = -1;

            ProcessConnections connections = new ProcessConnections(true);

            if (args.Length != 0)
            {
                if (int.TryParse(args[0], out pid))
                {
                    //by processID
                    printConnections(new ProcessConnectionsPayload[]
                    { connections.getProcessConnectionsByID(pid) }
                    );
                }
                else
                {
                    //by name
                    printConnections(connections.getProcessConnectionsByName(args[0]));
                }
            }
            else
            {
                //all processes
                printConnections(connections.getAllProcessesConnections());
            }
        }

        static void printConnections(ProcessConnectionsPayload[] payloads)
        {

            if (payloads != null)
            {
                for (int i = 0; i < payloads.Length; i++)
                {
                    if (payloads[i] == null) {
                        continue;
                    }

                    Console.WriteLine("#" + payloads[i].PID + ": " + payloads[i].name);
                    Console.WriteLine("#TCP:" + payloads[i].tcpConnections.Count);

                    for (int z = 0; z < payloads[i].tcpConnections.Count; z++)
                    {
                        Console.WriteLine("#" + payloads[i].tcpConnections[z].address
                            + " Source:" + payloads[i].tcpConnections[z].sourcePort
                            + " Destination:" + payloads[i].tcpConnections[z].destinationPort
                            + " State:" + payloads[i].tcpConnections[z].state);
                    }
                    Console.WriteLine("UDP:" + payloads[i].udpConnections.Count);
                    for (int z = 0; z < payloads[i].udpConnections.Count; z++)
                    {
                        Console.WriteLine("#" + payloads[i].udpConnections[z].address
                            + " Source:" + payloads[i].udpConnections[z].sourcePort
                            + " Destination:" + payloads[i].udpConnections[z].destinationPort
                            + " State:" + payloads[i].udpConnections[z].state);
                    }
                }
            }
