Question

In this exercise you will develop a C# application that allows the user to handle a Windows service. Create a class named ServiceController. Create the following properties: CanShutDown, CanStop, MachineName, ServiceName, ServiceType, Status. Create the following methods: Start, Stop, Close, and ToString to return service controller object information in a nicely formatted string.

Provide a constructor that allows the user to initialize ServiceController object information.

Write a driver class to test the ServiceController class. The driver class (main class) interacts with the user and calls ServiceController properties and methods to handle the service. Provide interaction with user. Allow user to input service information and use service methods and properties. Output the results.

Answer 1

Here is the c# application for service controller.

using System;
using System.ServiceProcess;
using System.Diagnostics;
using System.Threading;

namespace ServiceControllerSample
{
class Program
{
public enum SimpleServiceCustomCommands
{ StopWorker = 128, RestartWorker, CheckWorker };
static void Main(string[] args)
{
ServiceController[] scServices;
scServices = ServiceController.GetServices();

foreach (ServiceController scTemp in scServices)
{

if (scTemp.ServiceName == "Simple Service")
{
// Display properties for the Simple Service sample
// from the ServiceBase example.
ServiceController sc = new ServiceController("Simple Service");
Console.WriteLine("Status = " + sc.Status);
Console.WriteLine("Can Pause and Continue = " + sc.CanPauseAndContinue);
Console.WriteLine("Can ShutDown = " + sc.CanShutdown);
Console.WriteLine("Can Stop = " + sc.CanStop);
if (sc.Status == ServiceControllerStatus.Stopped)
{
sc.Start();
while (sc.Status == ServiceControllerStatus.Stopped)
{
Thread.Sleep(1000);
sc.Refresh();
}
}
// Issue custom commands to the service
// enum SimpleServiceCustomCommands
// { StopWorker = 128, RestartWorker, CheckWorker };
sc.ExecuteCommand((int)SimpleServiceCustomCommands.StopWorker);
sc.ExecuteCommand((int)SimpleServiceCustomCommands.RestartWorker);
sc.Pause();
while (sc.Status != ServiceControllerStatus.Paused)
{
Thread.Sleep(1000);
sc.Refresh();
}
Console.WriteLine("Status = " + sc.Status);
sc.Continue();
while (sc.Status == ServiceControllerStatus.Paused)
{
Thread.Sleep(1000);
sc.Refresh();
}
Console.WriteLine("Status = " + sc.Status);
sc.Stop();
while (sc.Status != ServiceControllerStatus.Stopped)
{
Thread.Sleep(1000);
sc.Refresh();
}
Console.WriteLine("Status = " + sc.Status);
String[] argArray = new string[] { "ServiceController arg1", "ServiceController arg2" };
sc.Start(argArray);
while (sc.Status == ServiceControllerStatus.Stopped)
{
Thread.Sleep(1000);
sc.Refresh();
}
Console.WriteLine("Status = " + sc.Status);
// Display the event log entries for the custom commands
// and the start arguments.
EventLog el = new EventLog("Application");
EventLogEntryCollection elec = el.Entries;
foreach (EventLogEntry ele in elec)
{
if (ele.Source.IndexOf("SimpleService.OnCustomCommand") >= 0 |
ele.Source.IndexOf("SimpleService.Arguments") >= 0)
Console.WriteLine(ele.Message);
}
}
}

}
}
}
