I usually use the following techinque to run the same app as a console application or as a service:
public static class Program
{
#region Nested classes to support running as service
public const string ServiceName = "MyService";
public class Service : ServiceBase
{
public Service()
{
ServiceName = Program.ServiceName;
}
protected override void OnStart(string[] args)
{
Program.Start(args);
}
protected override void OnStop()
{
Program.Stop();
}
}
#endregion
static void Main(string[] args)
{
if (!Environment.UserInteractive)
// running as service
using (var service = new Service())
ServiceBase.Run(service);
else
{
// running as console app
Start(args);
Console.WriteLine("Press any key to stop...");
Console.ReadKey(true);
Stop();
}
}
private static void Start(string[] args)
{
// onstart code here
}
private static void Stop()
{
// onstop code here
}
}
Environment.UserInteractive is normally true for console app and false for a service. Techically, it is possible to run a service in user-interactive mode, so you could check a command-line switch instead.
