将C＃控制台应用程序转换为服务（主方法不起作用）

我最近“转换”，或者更确切地说，我的方法导入到默认的Windows服务模板。 没有语法错误，编译好了，但FileSystemWatcher方法由于某种原因不能正常工作，例如，在正常运行时，它会写入已经创build到process.lst的所有进程，但是作为服务运行时，它不会执行这（也许是与工作目录，因为它的服务？）：

namespace WindowsService { class WindowsService : ServiceBase { /// <summary> /// Public Constructor for WindowsService. /// - Put all of your Initialization code here. /// </summary> public WindowsService() { this.ServiceName = "My Service"; this.EventLog.Source = "My Service"; this.EventLog.Log = "Application"; // These Flags set whether or not to handle that specific // type of event. Set to true if you need it, false otherwise. this.CanHandlePowerEvent = true; this.CanHandleSessionChangeEvent = true; this.CanPauseAndContinue = true; this.CanShutdown = true; this.CanStop = true; if (!EventLog.SourceExists("My Service")) EventLog.CreateEventSource("My Service", "Application"); } /// <summary> /// The Main Thread: This is where your Service is Run. /// </summary> static void Main() { ServiceBase.Run(new WindowsService()); // This checks for any existing running instances, if found the proess is terminated immidieately. if (System.Diagnostics.Process.GetProcessesByName(System.IO.Path.GetFileNameWithoutExtension(System.Reflection.Assembly.GetEntryAssembly().Location)).Count() > 1) return; DisplayInfo(); string dirPath = "C:\\"; FileSystemWatcher fileWatcher = new FileSystemWatcher(dirPath); fileWatcher.IncludeSubdirectories = true; fileWatcher.Filter = "*.exe"; // fileWatcher.Filter = "C:\\$Recycle.Bin"; // fileWatcher.Changed += new FileSystemEventHandler(FileWatcher_Changed); fileWatcher.Created += new FileSystemEventHandler(FileWatcher_Created); // fileWatcher.Deleted += new FileSystemEventHandler(FileWatcher_Deleted); // fileWatcher.Renamed += new RenamedEventHandler(FileWatcher_Renamed); fileWatcher.EnableRaisingEvents = true; // updated code while (true) { CleanUpDel(); StartRemoveDuplicate(); CompareFiles(); bool changes = ScanFileChanges(); if (!changes) { TrimColon("process_trim.lst", "process_trimmed.lst"); TrimWipe(); AddTMPIgnore(); SendAlert(); CompareOrig(); } Thread.Sleep(10000); } } private static void AddTMPIgnore() { var myString = File.ReadAllText("process_final.lst"); File.AppendAllText("ignore_temp.lst", myString); } static void FileWatcher_Created(object sender, FileSystemEventArgs e) { using (StreamWriter fileWriter = new StreamWriter("process.lst", true)) { var data = true; fileWriter.Write("C:\\" + e.Name + Environment.NewLine); } }
