Namespace: System.ServiceProcess
Assembly: System.ServiceProcess (in system.serviceprocess.dll)

public void Start ()
public void Start ()
public function Start ()

Exception typeCondition

Win32Exception

An error occurred when accessing a system API.

InvalidOperationException

The service cannot be started.

You cannot call Stop for the service until the service controller status is Running.

The following example uses the ServiceController class to check whether the Alerter service is stopped. If the service is stopped, the example starts the service and waits until the service status is set to Running.


// Check whether the Alerter service is started.

ServiceController sc  = new ServiceController();
sc.ServiceName = "Alerter";
Console.WriteLine("The Alerter service status is currently set to {0}", 
                   sc.Status.ToString());

if (sc.Status == ServiceControllerStatus.Stopped)
{
   // Start the service if the current status is stopped.

   Console.WriteLine("Starting the Alerter service...");
   try 
   {
      // Start the service, and wait until its status is "Running".
      sc.Start();
      sc.WaitForStatus(ServiceControllerStatus.Running);
   
      // Display the current service status.
      Console.WriteLine("The Alerter service status is now set to {0}.", 
                         sc.Status.ToString());
   }
   catch (InvalidOperationException)
   {
      Console.WriteLine("Could not start the Alerter service.");
   }
}

// Check whether the Alerter service is started.
ServiceController sc = new ServiceController();
sc.set_ServiceName("Alerter");
Console.WriteLine("The Alerter service status is currently set to {0}",
    sc.get_Status().ToString());

if (sc.get_Status().Equals(ServiceControllerStatus.Stopped)) {
    // Start the service if the current status is stopped.
    Console.WriteLine("Starting the Alerter service...");
    try {
        // Start the service, and wait until its status is 
        // "Running".
        sc.Start();
        sc.WaitForStatus(ServiceControllerStatus.Running);
        // Display the current service status.
        Console.WriteLine("The Alerter service status is now set to {0}.",
            sc.get_Status().ToString());
    }
    catch (InvalidOperationException exp) {
        Console.WriteLine("Could not start the Alerter service.");
    }
}
