Check if a process is running on a remote system using C#

Question

I am trying to check if a process is running on a remote system. I am using the following code:

string procSearc = "notepad";
string remoteSystem = "remoteSystemName";

Process[] proce = System.Diagnostics.Process.GetProcessesByName(procSearch, remoteSystem);

However, when I try to run the code, I get the following error: "Couldn't connect to remote machine."

I am able to run pslist with the following command: C:>pslist \remoteSystemName So I know it is possible to get the information I need, but I need it in the code.

Another possibility would be to integrate pslist into C# and search the list to see if the process is there, but I have not found information on how to do this.

Use the System.ServiceProcess.ServiceController class for a service. You can use Status to check if it's running and the Stop() and Start() to control it.

ServiceController sc = new ServiceController();
            sc.MachineName = remoteSystem;
            sc.ServiceName = procSearc;

            if(sc.Status.Equals(ServiceControllerStatus.Running))
            { sc.Stop(); }
            else
            { sc.Start(); }

Does the inner Exception say "Access Denied"?

Below is what I did to get this to work:

First I added a reference to System.ServiceProcess and added: using System.ServiceProcess;

string remoteSystem = "remoteSystemName";
string procSearch = "notepad";            
Process[] proc = System.Diagnostics.Process.GetProcessesByName(procSearch, remoteSystem);

   if (proc.Length > 0)

   {
        Console.WriteLine("Able to find: " + proc[0]);
   }
   else
   {
        Console.WriteLine("Unable to find: " + procSearch);
   }
