How to check windows service is running or not in c#.

Hi All,

I have created console application to verify the installed service status running or stopped.

Below are code.

1) Add below the keys in your application.

 <add key ="ServicesName" value="SCardSvr,SNMPTRAP,Appinfo"></add>

  <add key ="ToEmail" value="abc@gmail.com"></add>

  <add key ="ProjectName" value="HIP Teva"/>

  <add key ="EnvironmentName" value="Test"/>

  <add key ="FromEmail" value="abc@gmail.com"/>

   <!--Email body in in key-->

   <add key="EmailTemplate" value="Hi %ToEmail% , &lt;br&gt;&lt;br&gt;Please verify below service on  %environmentName% environment. &lt;br&gt; &lt;br&gt; %stoppedServices% Sever IP address : %serverIP% &lt;br&gt;&lt;br&gt;&lt;br&gt; Thanks"></add>

2) Add System.ServiceProcess on your project references from NuGet

3) Add below code.

 static void Main(string[] args)

        {

            var serviceNamesCommaseparated = ConfigurationManager.AppSettings.Get("ServicesName");

            string stoppedService = string.Empty;

            if (!string.IsNullOrEmpty(serviceNamesCommaseparated))

            {

                var serviceNamelist = serviceNamesCommaseparated.Split(new[] { ',' }, StringSplitOptions.RemoveEmptyEntries);

                // To Loop through

                foreach (string servicename in serviceNamelist)

                {

                    if (!string.IsNullOrEmpty(servicename))

                    {

                        var status = GetServiceStatus(servicename);

                        if (status == "Stopped" || status == "Stopping" || status == "Paused")

                        {

                            stoppedService = stoppedService + "Service Name: " + servicename + " || Status: " + status + "</br></br>";

                        }

                    }

                }

                if (!string.IsNullOrEmpty(stoppedService))

                {

                    //Send Emial to the admin and also log in log file 

                    WriteLog("Services status : " + stoppedService + "");

                    sendemail(stoppedService);

                }

            }

        }

        private static string GetServiceStatus(string serviceName)

        {

            // Verify server name is installed or not in server

            var getallservices = ServiceController.GetServices();

            string serviceStatus = string.Empty;

            if (getallservices.Where(q => q.ServiceName == serviceName) != null)

            {

                ServiceController sc = new ServiceController(serviceName);

                switch (sc.Status)

                {

                    case ServiceControllerStatus.Running:

                        return "Running";

                    case ServiceControllerStatus.Stopped:

                        return "Stopped";

                    case ServiceControllerStatus.Paused:

                        return "Paused";

                    case ServiceControllerStatus.StopPending:

                        return "Stopping";

                    case ServiceControllerStatus.StartPending:

                        return "Starting";

                    default:

                        return "Status Changing";

                }

            }

            else

            {

                WriteLog("Provided service is not installed in server " + serviceName + "");

            }

            return serviceStatus;

        }

        public static bool WriteLog(string strMessage)

        {

            try

            {

                StreamWriter log;

                if (!File.Exists("logfile.txt"))

                {

                    log = new StreamWriter("logfile.txt");

                }

                else

                {

                    log = File.AppendText("logfile.txt");

                }

                // Write to the file:

                log.WriteLine(DateTime.Now);

                log.WriteLine(strMessage);

                log.WriteLine();

                // Close the stream:

                log.Close();

                return true;

            }

            catch (Exception ex)

            {

                return false;

            }

        }

        public static void sendemail(string stoppedServices)

        {

            try

            {

                MailMessage mm = new MailMessage();

                mm.From = new MailAddress(ConfigurationManager.AppSettings.Get("FromEmail"));

                mm.Subject = ConfigurationManager.AppSettings.Get("ProjectName");

                var ToEmail = ConfigurationManager.AppSettings.Get("ToEmail");

                var environmentName = ConfigurationManager.AppSettings.Get("EnvironmentName");

                mm.Subject = ConfigurationManager.AppSettings.Get("ProjectName");

                string fRecepientEmail = ConfigurationManager.AppSettings.Get("FromEmail");

                string EmailTemplate = ConfigurationManager.AppSettings.Get("EmailTemplate");

                string hostName = Dns.GetHostName(); // Retrive the Name 

                string serverIP = Dns.GetHostByName(hostName).AddressList[0].ToString();

                mm.Body = EmailTemplate.Replace("%ToEmail%", ToEmail).Replace("%environmentName%", environmentName).Replace("%stoppedServices%", stoppedServices).Replace("%serverIP%", serverIP);

                foreach (var RecepientEmail in fRecepientEmail.Split(new[] { "," }, StringSplitOptions.RemoveEmptyEntries)) { mm.To.Add(RecepientEmail); }

                mm.IsBodyHtml = true;

                SmtpClient smtpMail = new SmtpClient();

                smtpMail.Send(mm);

            }

            catch (SmtpException smEx)

            {

                WriteLog(smEx.InnerException.ToString());

            }

        }

I have added to all services that need to be verify in web.config file. If services are stopped or postponed then application send the email in provided email. 

Thanks for reading.
