FileSystemWatcher不监视Vista中的本地用户文件夹或临时Internet文件夹（64位）

我写了一个测试程序来监控我的Picture文件夹，它指向同一用户的c：\ users [用户名] \图片和临时互联网文件文件夹。 如果我将文件夹更改为d：\ persona_pics等其他位置，这个程序可以正常工作。 当我将上述文件夹设置为监视时，不知道为什么没有引发事件？

这是代码。

class Program { static void Main(string[] args) { //FileSystemWatcher myJpegFileWatcher = new FileSystemWatcher(@"C:\Users\[username]\AppData\Local\Microsoft\Windows\Temporary Internet Files\low\content.ie5\"); FileSystemWatcher myJpegFileWatcher = new FileSystemWatcher(@"C:\Users\[username]\Pictures\ "); myJpegFileWatcher.Filter = "*.jpg"; myJpegFileWatcher.Created += new FileSystemEventHandler(myJpegFileWatcher_Created); myJpegFileWatcher.Changed += new FileSystemEventHandler(myJpegFileWatcher_Changed); myJpegFileWatcher.IncludeSubdirectories = true; myJpegFileWatcher.NotifyFilter = NotifyFilters.CreationTime; myJpegFileWatcher.EnableRaisingEvents = true; Console.Read(); } static void myJpegFileWatcher_Changed(object sender, FileSystemEventArgs e) { FileInfo duplicateFile = new FileInfo(@e.FullPath); bool flag = true; while (flag) { try { if (duplicateFile.Length > 20000) { duplicateFile.CopyTo(@"d:\pics\spy\ " + e.Name); flag = false; StreamWriter fs = new StreamWriter(@"d:\pics\log.txt", true); fs.WriteLine("file is being copied:{0}, Size={1}", e.FullPath, duplicateFile.Length); fs.Close(); } else { StreamWriter fs = new StreamWriter(@"d:\pics\log.txt", true); fs.WriteLine("file is not being copied:{0}, Size={1}", e.FullPath, duplicateFile.Length); fs.Close(); } } catch (Exception ex) { // } } } static void myJpegFileWatcher_Created(object sender, FileSystemEventArgs e) { FileInfo duplicateFile = new FileInfo(@e.FullPath); bool flag = true; while (flag) { try { if (duplicateFile.Length > 20000) { duplicateFile.CopyTo(@"d:\pics\spy\ " + e.Name); flag = false; StreamWriter fs = new StreamWriter(@"d:\pics\log.txt", true); fs.WriteLine("file is being copied:{0}, Size={1}", e.FullPath, duplicateFile.Length); fs.Close(); } } catch (Exception ex) { // } } } } 

工作代码..

class Program {static void Main（string [] args）{

  FileSystemWatcher myJpegFileWatcher = new FileSystemWatcher(@"C:\Users\[user]\Pictures\"); myJpegFileWatcher.Filter = "*.jpg"; myJpegFileWatcher.Changed += new FileSystemEventHandler(myJpegFileWatcher_Changed); myJpegFileWatcher.IncludeSubdirectories = true; myJpegFileWatcher.EnableRaisingEvents = true; Console.Read(); } static void myJpegFileWatcher_Changed(object sender, FileSystemEventArgs e) { FileInfo duplicateFile = new FileInfo(@e.FullPath); bool flag = true; while (flag) { try { if (duplicateFile.Exists) { if (duplicateFile.Length > 20000) { try { duplicateFile.CopyTo(@"d:\pics\spy\" + e.Name,true); } catch (Exception ex) { StreamWriter fs = new StreamWriter(@"d:\pics\log.txt", true); fs.WriteLine("Error Inside copying:{0}", ex.Message); fs.Close(); } finally { flag = false; StreamWriter fs = new StreamWriter(@"d:\pics\log.txt", true); fs.WriteLine("file is being copied:{0}, Size={1}", e.FullPath, duplicateFile.Length); fs.Close(); } } else { StreamWriter fs = new StreamWriter(@"d:\pics\log.txt", true); fs.WriteLine("file is not being copied:{0}, Size={1}", e.FullPath, duplicateFile.Length); fs.Close(); } } } catch (Exception ex) { StreamWriter fs = new StreamWriter(@"d:\pics\log.txt", true); fs.WriteLine("Error:{0}", ex.Message); fs.Close(); } } } }

尝试运行FileMon（通过MSDN可用的SysInternals工具）。 它将显示您的代码在文件系统上实际执行的操作。 然后，当您将代码指向“我的图片”等时，您可能能够找出原因或行为完全不同的原因。
