C# 使用FileSystemWatcher监视文件系统

我使用

FileSystemWatcher

来监视文件系统。它可以监视特定文件夹或驱动器

但我希望它在整个文件系统上，这意味着它应该在所有驱动器上进行监视

你知道吗

我经常这么做

public static void Run()
{
     string[] args = System.Environment.GetCommandLineArgs();

     if (args.Length < 2)
     {
          Console.WriteLine("Usage: Watcher.exe PATH [...] [PATH]");
          return;
     }
     List<string> list = new List<string>();
     for (int i = 1; i < args.Length; i++)
     {
          list.Add(args[i]);
     }

     foreach (string my_path in list)
     {
          WatchFile(my_path);
     }

     Console.WriteLine("Press \'q\' to quit the sample.");
     while (Console.Read() != 'q') ;
}
private static void WatchFile(string watch_folder)
{
    watcher.Path = watch_folder;

    watcher.NotifyFilter = NotifyFilters.LastWrite;
    watcher.Filter = "*.xml";
    watcher.Changed += new FileSystemEventHandler(convert);
    watcher.EnableRaisingEvents = true;
}

publicstaticvoidrun（）
{
字符串[]args=System.Environment.GetCommandLineArgs（）；
如果（参数长度<2）
{
WriteLine（“用法：Watcher.exe路径[…][PATH]”；
回来
}
列表=新列表（）；
for（int i=1；i

使用一种方法是枚举所有目录，并通过在每个目录上使用

FileSystemWatcher

来监视所有目录

---

但是它会消耗大量的资源。因此，您可以查看此链接：

您可以使用IncludeSubdirectories到逻辑驱动器来查看整个系统。 试试这个代码

string[] drives = Environment.GetLogicalDrives();

foreach(string drive in drives)
{
   FileSystemWatcher watcher = new FileSystemWatcher();
   watcher.Path = drive;
   watcher.IncludeSubdirectories = true;
   watcher.NotifyFilter = NotifyFilters.LastAccess | NotifyFilters.LastWrite
                   | NotifyFilters.FileName | NotifyFilters.DirectoryName;

   watcher.Filter = "*.txt";

   watcher.Changed += new FileSystemEventHandler(OnChanged);
   watcher.Created += new FileSystemEventHandler(OnChanged);
   watcher.Deleted += new FileSystemEventHandler(OnChanged);
   watcher.Renamed += new RenamedEventHandler(OnRenamed);

   watcher.EnableRaisingEvents = true;
}
