How to get running windows service process id ?

Question

Hello All,

I'm trying to find out information on currently running windows service processes. I looked at following API, I could get the display name ,but not the process id of each running service. I need both service name (first one on General tab on service properties ) and process id.

I looked at ManagementObject's GetProperty, I can get  Name, caption etc but not process id.
I looked at ServiceController,I can get Display Name, status etc,but not the process id.

I looked at Process class, where I can get id (property Id), but not the service name.

Appreciate your help

First add reference of System.Management, System.ServiceProcess in your project.

and try with below functions:

 private uint GetProcessIDByServiceName(string serviceName)
    {
      uint processId = 0;
      string qry = "SELECT PROCESSID FROM WIN32_SERVICE WHERE NAME = '" + serviceName + "'";
      System.Management.ManagementObjectSearcher searcher = new System.Management.ManagementObjectSearcher(qry);
      foreach (System.Management.ManagementObject mngntObj in searcher.Get())
      {
        processId = (uint)mngntObj["PROCESSID"];
      }
      return processId;
    }

    private uint GetProcessIDByServiceDisplayName(string serviceDisplayName)
    {
      uint processId = 0;
      string qry = "SELECT PROCESSID FROM WIN32_SERVICE WHERE DISPLAYNAME = '" + serviceDisplayName + "'";
      System.Management.ManagementObjectSearcher searcher = new System.Management.ManagementObjectSearcher(qry);
      foreach (System.Management.ManagementObject mngntObj in searcher.Get())
      {
        processId = (uint)mngntObj["PROCESSID"];
      }
      return processId;
    }

    private List<System.ServiceProcess.ServiceController> GetRunningServices()
    {
      System.ServiceProcess.ServiceController[] services = System.ServiceProcess.ServiceController.GetServices();      
      List<System.ServiceProcess.ServiceController> running = new List<System.ServiceProcess.ServiceController>();

      foreach (System.ServiceProcess.ServiceController item in services)
      {
        if (item.Status == System.ServiceProcess.ServiceControllerStatus.Running)
        {
          running.Add(item);
        }
      }
      return running;
    }
