OK, here's the WMI code to list the running services and (via the Process Id) their associated processes.

The process for many of the services will be shown as svchost (see http://en.wikipedia.org/wiki/Svchost)

You'll need to add a reference to System.Management.dll to run this code:

using System;
using System.Management;
using System.Diagnostics;

class Test
{
static void Main()
{
Console.Clear();
Console.WriteLine("{0,-30} {1,-5} {2}", "Service", "Pid", "Process");
Console.WriteLine("{0,-30} {1,-5} {2}\n", "-------", "---", "-------");
ManagementObjectSearcher mos = new ManagementObjectSearcher("Select * From Win32_Service");

foreach(ManagementObject mo in mos.Get())
{
string state = (string)mo["state"];
if(state == "Running")
{
int processId = (int)(uint)mo["ProcessId"];
Process p = Process.GetProcessById(processId);
Console.WriteLine("{0,-30} {1,-5} {2}", mo["Name"], processId, p.ProcessName);
}
}

Console.ReadKey();
}
}

The problem with your code is that you're continually overwriting txtAllProcess.Text with the name of each service, so you just end up with one.

If it's a multi-line textbox, then use:

txtAllProcess.Text += s.ServiceName + "\r\n";

I can't see any obvious way in either the Process class or the ServiceController class to associate one with the other.

However, you can associate a service with its ProcessId and then look up the Process object using Process.GetProcessById() if you use WMI to get the list of services. See the Win32_Service class (http://msdn.microsoft.com/en-us/library/aa394418(VS.85).aspx).

I'm about to go out so I haven't time to write the code just now but, if you haven't figured it out by then, I'll do something later today.

and this is my code for listing running services

private void btnListServices_Click(object sender, EventArgs e)
{
try
{
ServiceController[] sc = ServiceController.GetServices();
foreach (ServiceController s in sc)
{
if (s.Status.ToString() == "Running")
{
txtAllProcess.Text = s.ServiceName;
}
}

}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}
can anyone see what is the problem?

what about listing which service runs which process?

I don't know how you're doing it but the following code works fine on my Windows 7 machine returning all running services including device drivers.

You need a reference to System.ServiceProcess.dll to run this:

using System;
using System.ServiceProcess;

class Test
{
static void Main()
{
Console.WriteLine("List of running non-device driver services:\n");

foreach(ServiceController sc in ServiceController.GetServices())
{
if (sc.Status == ServiceControllerStatus.Running)
Console.WriteLine(sc.DisplayName);
}

Console.WriteLine("\nList of running device driver services:\n");

foreach(ServiceController sc in ServiceController.GetDevices())
{
if (sc.Status == ServiceControllerStatus.Running)
Console.WriteLine(sc.DisplayName);
}

Console.ReadKey();
}
}
