Constantly monitor processes

I've written some code which monitors the running windows processes.
I wish to know when a certain process starts and when it ends.
The code works just like I want it to.

Now, I wish to implement it in a windows form server application - so it will run in loop as long as the form is alive. I guess I should make it run asynchronously maybe using a

BackgroundWorker
. I'm just not sure what's the best way to do it and how.

Here is my monitor code:

using System;
using System.Management;
using System.Diagnostics;
using System.Collections.Generic;
using System.ComponentModel;

class ProcessMonitor
{
public static void Main()
{
Dictionary<string, Process> newProcs= new Dictionary<string, Process> ();
while (true)
{
foreach (Process process in Process.GetProcesses())
{
if (process.ProcessName.CompareTo("Someprocess") == 0)
{
if (!searchForProcess(newProcs, process.Id))
{
ManagementObjectSearcher searcher = new ManagementObjectSearcher("SELECT CommandLine FROM Win32_Process WHERE ProcessId = " + process.Id);
foreach (ManagementObject @object in searcher.Get())
{
Console.Write("Adding new Process: ");
Console.WriteLine(@object["CommandLine"] + " ");
newProcs.Add(@object["CommandLine"] + " ", process);
}
}
}
}
checkProcesses(newProcs);
}
Console.WriteLine("Done");
}

private static bool searchForProcess(Dictionary<string, Process> newProcs, int newKey)
{
foreach (Process process in newProcs.Values)
{
if (process.Id == newKey)
return true;
}

return false;
}
private static void checkProcesses(Dictionary<string, Process> newProcs)
{
foreach (string currProc in newProcs.Keys)
{
bool processExists = false;
foreach (Process process in Process.GetProcesses())
{
if (process.Id == newProcs[currProc].Id)
{
processExists = true;
break;
}

}
if (!processExists)
{
Console.Write("Process Finished: ");
Console.WriteLine(currProc);
newProcs.Remove(currProc);
if (newProcs.Count == 0)
break;
}
}
}
}


Any ideas?

Answer

u can create a method like this

 public static void Thread1() {
           //paste your main code hear
            }

copy and past all your code, written in the main to this new method.

change the main to some like this

 public static void Main() {
            Console.WriteLine("Before start thread");
            Thread tid1 = new Thread(new ThreadStart(Thread1 ) );
            tid1.Start();                
    }
