How to get string output when converting a console application into a .dll?

[momo2012]

hello,

I want to convert a console application to a .dll file,and get the result when load the dll,what I don't know is how to get the result in a dll file after converted.Below is the origin console code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Net.NetworkInformation;
using System.Diagnostics;
using System.Net;
using System.Threading;
using System.Net.Sockets;

namespace ConsoleApplication1
{
class Program
{
static CountdownEvent countdown;
static int upCount = 0;
static object lockObj = new object();
const bool resolveNames = true;

static void Main(string[] args)
{
countdown = new CountdownEvent(1);
Stopwatch sw = new Stopwatch();
sw.Start();
string ipBase = "192.168.1.";
for (int i = 1; i < 255; i++)
{
string ip = ipBase + i.ToString();

Ping p = new Ping();
p.PingCompleted += new PingCompletedEventHandler(p_PingCompleted);
countdown.AddCount();
p.SendAsync(ip, 100, ip);
}
countdown.Signal();
countdown.Wait();
sw.Stop();
TimeSpan span = new TimeSpan(sw.ElapsedTicks);
Console.WriteLine("Took {0} milliseconds. {1} hosts active.", sw.ElapsedMilliseconds, upCount);
Console.ReadLine();
}

static void p_PingCompleted(object sender, PingCompletedEventArgs e)
{
string ip = (string)e.UserState;
if (e.Reply != null && e.Reply.Status == IPStatus.Success)
{
if (resolveNames)
{
string name;
try
{
IPHostEntry hostEntry = Dns.GetHostEntry(ip);
name = hostEntry.HostName;
}
catch (SocketException ex)
{
name = "?";
}
Console.WriteLine("{0} ({1}) is up: ({2} ms)", ip, name, e.Reply.RoundtripTime);
}
else
{
Console.WriteLine("{0} is up: ({1} ms)", ip, e.Reply.RoundtripTime);
}
lock (lockObj)
{
upCount++;
}
}
else if (e.Reply == null)
{
Console.WriteLine("Pinging {0} failed. (Null Reply object?)", ip);
}
countdown.Signal();
}
}
}
