Answer 1

Try the following:

When you install the service, specify the startup type as Automatic. This can be done using the sc.exe command or through the service installer configuration.

Also note that Windows services do not have a user interface, so avoid using constructs like Console.WriteLine() or Console.ReadLine() as they won't work in a service context.

Updated Code

using System;
using System.Diagnostics;
using System.IO;
using System.ServiceProcess;

namespace SerV_
{
    public partial class Service1 : ServiceBase
    {
        private FileSystemWatcher watcher;
        private const string TargetPath = @"C:\Users\sy\Documents\test22";

        public Service1()
        {
            InitializeComponent();
        }

        protected override void OnStart(string[] args)
        {
            try
            {
                watcher = new FileSystemWatcher(@"C:\");
                watcher.NotifyFilter = NotifyFilters.Attributes
                                     | NotifyFilters.CreationTime
                                     | NotifyFilters.DirectoryName
                                     | NotifyFilters.FileName
                                     | NotifyFilters.LastAccess
                                     | NotifyFilters.LastWrite
                                     | NotifyFilters.Security
                                     | NotifyFilters.Size;

                watcher.Created += OnCreated;
                watcher.Filter = "*.*";
                watcher.IncludeSubdirectories = true;
                watcher.EnableRaisingEvents = true;

                Log("Service started successfully.");
            }
            catch (Exception ex)
            {
                Log($"Error starting service: {ex.Message}");
            }
        }

        protected override void OnStop()
        {
            watcher?.Dispose();
            Log("Service stopped.");
        }

        private void OnCreated(object sender, FileSystemEventArgs e)
        {
            try
            {
                FileInfo fileInfo = new FileInfo(e.FullPath);
                var targetFile = Path.Combine(TargetPath, fileInfo.Name);
                File.Copy(e.FullPath, targetFile, true);
                Log($"File {e.FullPath} copied to {targetFile}.");
            }
            catch (Exception ex)
            {
                Log($"Error copying file: {ex.Message}");
            }
        }

        private void Log(string message)
        {
            string source = "MyServiceLog";
            if (!EventLog.SourceExists(source))
            {
                EventLog.CreateEventSource(source, "Application");
            }

            EventLog.WriteEntry(source, message, EventLogEntryType.Information);
        }
    }
}

To Install the Service

1. Create a Service Installer: Add a new installer class to your project to configure the service. Here's an example:

      using System.ServiceProcess;
      using System.Configuration.Install;
   
      [RunInstaller(true)]
      public class ProjectInstaller : Installer
      {
          public ProjectInstaller()
          {
              ServiceProcessInstaller processInstaller = new ServiceProcessInstaller
              {
                  Account = ServiceAccount.LocalSystem
              };
   
              ServiceInstaller serviceInstaller = new ServiceInstaller
              {
                  StartType = ServiceStartMode.Automatic,
                  ServiceName = "MyService"
              };
   
              Installers.Add(processInstaller);
              Installers.Add(serviceInstaller);
          }
      }
   

2. Build the Service: Build the project to generate the executable.
3. Install the Service: Use the InstallUtil.exe tool to install the service:

      InstallUtil.exe YourService.exe
