【问题描述】：
我编写了一个基本应用程序，它监视一个网络文件共享目录，当在该目录中创建一个新文件时，它会触发一个解析该文件的外部应用程序。我还使用本地目录进行了测试，一切正常。我已经用这样的调试代码对其进行了测试，并且该应用程序可以正常工作：
#if DEBUG
Service1 mysService1 = new Service1();
mysService1.OnDebug(); //calls onStart(Null);
System.Threading.Thread.Sleep(System.Threading.Timeout.Infinite);
#else
ServiceBase[] ServicesToRun;
ServicesToRun = new ServiceBase[]
{
new Service1()
};
ServiceBase.Run(ServicesToRun);
System.Threading.Thread.Sleep(System.Threading.Timeout.Infinite);
#endif
然后，当我切换到发布、构建和安装服务时，什么都不会发生。因此，由于路径有效，我认为这取决于权限？
我去了Task Manager>Services>Services..>，右击我的service>Properties>Log On>，并给了它我的凭据。
我还转到了我的应用程序在网络上的根文件夹Right click>Security>Edit。然后我给了我的帐户修改、读取和执行、列出文件夹内容和读取权限，当然这些权限会传播到其层次结构下的所有文件夹。
我什至尝试将它映射到网络驱动器 Z 并尝试访问它。
尽管我尝试了一切，但服务仍然拒绝做任何事情。我添加了更多调试代码，我将在其中检查文件是否已更改或删除并将其写在文本文件中。它会再次工作并在调试中检测到这些更改，但安装后什么都不会发生。
我很确定这可能仍然是某种权限问题，谁能告诉我我还能做些什么来解决这个问题？
编辑：
有人要求提供更多代码。另请注意，我的 Utility 类能够生成堆栈跟踪。它导致 System.IO.FileStream 错误从 FileWatcher.cs System.IO.File.AppendAllText(PathLocation() + "\logFile.txt", Environment.NewLine + " Started! " + DateTime.Now.ToString());
Service1.cs：
public Service1()
{
InitializeComponent();
}
public void OnDebug()
{
OnStart(null);
}
protected override void OnStart(string[] args)
{
try
{
FileWatcher f = new FileWatcher();
}
catch (Exception e)
{
new ErrorMailer(e, DateTime.Now.ToString());
}
}
FileWatcher.cs：
private FileSystemWatcher _fileWatcher;
static ProcessStartInfo start;
public FileWatcher()
{
System.IO.File.AppendAllText(PathLocation() + "\\logFile.txt", Environment.NewLine + " Started! " + DateTime.Now.ToString());
_fileWatcher = new FileSystemWatcher(PathLocation());
HasMailClerkBeenRun = false;
start = new ProcessStartInfo();
_fileWatcher.Created += new FileSystemEventHandler(_fileWatcher_Created);
_fileWatcher.Deleted += new FileSystemEventHandler(_fileWatcher_Deleted);
_fileWatcher.Changed += new FileSystemEventHandler(_fileWatcher_Changed);
_fileWatcher.EnableRaisingEvents = true;
}
{
string value = String.Empty;
value = @"Z:\MyAppDirectory\DirectoryFileWatcherIsWatching"; //@"\\FileShareName\RootDirectory\MyAppDirectory\DirectoryFileWatcherIsWatching";
return value;
}
void _fileWatcher_Changed(object sender, FileSystemEventArgs e)
{
System.IO.File.AppendAllText(PathLocation() + "\\logFile.txt", Environment.NewLine + "Started from the bottom now we changed! " + DateTime.Now.ToString());
}
void _fileWatcher_Deleted(object sender, FileSystemEventArgs e)
{
System.IO.File.AppendAllText(PathLocation() + "\\logFile.txt", Environment.NewLine + "Started from the bottom now we deleted! " + DateTime.Now.ToString());
}
void _fileWatcher_Created(object sender, FileSystemEventArgs e)
{
System.IO.File.AppendAllText(PathLocation() + "\\logFile.txt", Environment.NewLine + "Started from the bottom now we here! " + DateTime.Now.ToString());
LaunchExternalApp();
}
private void LaunchExternalApp()
{
start.UseShellExecute = false;
start.RedirectStandardError = true;
start.RedirectStandardInput = true;
start.RedirectStandardOutput = true;
start.CreateNoWindow = true;
start.ErrorDialog = false;
start.WindowStyle = ProcessWindowStyle.Hidden;
start.FileName =@"Z:\MyAppDirectory\AppExcutionLocation\MyApp.exe"
Thread thread1 = new Thread(new ThreadStart(A));
thread1.Start();
thread1.Join();
}
static void A()
{
using (Process proc = Process.Start(start))
{
proc.WaitForExit();
//HasMailClerkBeenRun = true;
// Retrieve the app's exit code
/// int exitCode = proc.ExitCode;
}
Thread.Sleep(100);
Console.WriteLine('A');
}
