list and control all services in current machine/or remote machine

Below code I found useful from THIS[^] thread would be a way for you to retrieve all the service from current machine.

RegistryKey rk = Registry.LocalMachine;
rk = rk.OpenSubKey(@"SYSTEM\CurrentControlSet\Services");
foreach (string keyName in  rk.GetSubKeyNames())
{
Console.WriteLine(keyName);
}

Hope it helps.

Pretty much the same way as with Process (see my answer to your question on Processes.

Add reference to assembly System.ServiceProcess.

using System.ServiceProcess;

//..

void DoWhatYouWantWithYourService(ServiceController controller) {
    /* some code */
}

foreach (ServiceController controller in ServiceController.GetServices())
    DoWhatYouWantWithYourService(controller);

There is also an overloaded version of GetServices for specified machine:

public static ServiceController[] GetServices(
	string machineName
)

This is a complete answer. Who knows how do you want to "control" your services?
