在服务的OnStart上获取服务的过程ID

Question

I have a Windows Service that i create.

I need to get the PID of the process when running and save it to DB.

On My OnStart

timer1 = new Timer();
double Interval = Convert.ToDouble(ConfigurationManager.AppSettings["intervalInSeconds"].ToString());
this.timer1.Interval = Interval * 1000;
this.timer1.Elapsed += new System.Timers.ElapsedEventHandler(this.timer1_Tick);
timer1.Enabled = true;

Library.WriteErrorLog("service started");

I Tried to get the PID using

GetService but it dosent work.

You can query if from the Managementobject like list

private static 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;
 }
