如何在C＃中浏览本地虚拟文件夹？

在我的C＃程序中，我必须浏览目录。 所以我使用方法System.IO.Directory.GetFiles(directory) ，当目录是像“C：\ Program File”这样的真实目录时，它运行良好，但当它是一个虚拟目录（例如：librairie目录）时，目录值看起来像这个：“:: {031E4825-7B94-4dc3-B131-E946B44C8DD5} \ Pictures.library-ms”我不知道如何浏览它。

Answer 1

您需要将虚拟路径转换为物理路径，尝试：

 DirectoryInfo directoryInfo = new DirectoryInfo(Server.MapPath("your virtual folder here")); 

您可能想要阅读DirectoryInfo 。 如果这没用，请试试这个：

 DirectoryInfo info = new DirectoryInfo("virtual folder here"); FileInfo[] files = info.GetFiles("*.*", SearchOption.AllDirectories);

我知道这很疯狂，但如果有人想要解决方案，这就是我在过去半天看到的这一点。 有几个解决方案可以为你提供文件夹名称，如果你给它提供虚拟文件夹的XML位置的路径 ，但我见过的任何东西都没有从::{031E4825-....} 。 在使用WindowsAPICodePack的KnownFoldersBrowser示例的另一个问题的答案中有一个提示 。 所以我通读了源代码并提出了以下内容：

这是我用来获取文件夹的DialogBox，我已经为AllowNonFileSystemItems启用了它，它允许选择库文件夹：

 Microsoft.WindowsAPICodePack.Dialogs.CommonOpenFileDialog dlg = new Microsoft.WindowsAPICodePack.Dialogs.CommonOpenFileDialog(); dlg.Title = "Pick Folder"; dlg.IsFolderPicker = true; dlg.InitialDirectory = Environment.SpecialFolder.Personal.ToString(); // If default setting does not exist, pick the Personal folder dlg.AddToMostRecentlyUsedList = false; dlg.AllowNonFileSystemItems = true; dlg.DefaultDirectory = dlg.InitialDirectory; dlg.EnsurePathExists = true; dlg.EnsureFileExists = false; dlg.EnsureReadOnly = false; dlg.EnsureValidNames = true; dlg.Multiselect = true; dlg.ShowPlacesList = true; if (dlg.ShowDialog() == Microsoft.WindowsAPICodePack.Dialogs.CommonFileDialogResult.Ok) { foreach ( string dirname in dlg.FileNames ) { var libFolders = ExpandFolderPath(dirname); if ( libFolders == null ) { MessageBox.Show("Could not add '" + dirname + "', please try another."); } else { foreach ( string libfolder in libFolders ) { DoWork(libfolder); } } } } 

然后我遍历allSpecialFolders以找到同样的::{031E4825-...} ，这是SpecialFolder的ParsingName（是的，可能是更优雅的方式）。 之后，使用来自其他解决方案的XML读取（ 我使用了做同样事情的CodeProject示例 ）来获取该库文件夹中的文件夹：

  /// 
Gets the folders associated with a path
 ///  /// Folder, or List of folders in library, and null if there was an issue public List ExpandFolderPath(string foldername) { List dirList = new List { }; // If the foldername is an existing directory, just return that if ( System.IO.Directory.Exists(foldername) ) { dirList.Add(foldername); return dirList; } // It's not a directory, so check if it's a GUID Library folder ICollection allSpecialFolders = Microsoft.WindowsAPICodePack.Shell.KnownFolders.All; Regex libguid = new Regex(@"\b([A-F0-9]{8}(?:-[A-F0-9]{4}){3}-[A-F0-9]{12})\b"); var match = libguid.Match(foldername); if ( match == null ) return null; string fpath = ""; // Iterate over each folder and find the one we want foreach ( var folder in allSpecialFolders ) { if ( folder.ParsingName == foldername ) { // We now have access to the xml path fpath = folder.Path; break; } } if ( fpath == "" ) { // Could not find it exactly, so find one with the same prefix, and // replace the filename foreach ( var folder in allSpecialFolders ) { if ( folder.ParsingName.Contains(match.Groups[1].Value) ) { string sameDir = System.IO.Path.GetDirectoryName(folder.Path); string newPath = System.IO.Path.Combine(sameDir, match.Groups[2].Value); if ( System.IO.File.Exists(newPath) ) fpath = newPath; break; } } } if ( fpath == "" ) return null; var intFolders = GetLibraryInternalFolders(fpath); return intFolders.Folders.ToList(); } /// 
 /// Represents an instance of a Windows 7 Library /// 
 public class Win7Library { public Win7Library() { } public string Name { get; set; } public string[] Folders { get; set; } } [DllImport("shell32.dll")] static extern int SHGetKnownFolderPath( [MarshalAs(UnmanagedType.LPStruct)] Guid rfid, uint dwFlags, IntPtr hToken, out IntPtr pszPath ); //Handles call to SHGetKnownFolderPath public static string getpathKnown( Guid rfid ) { IntPtr pPath; if ( SHGetKnownFolderPath(rfid, 0, IntPtr.Zero, out pPath) == 0 ) { string s = System.Runtime.InteropServices.Marshal.PtrToStringUni(pPath); System.Runtime.InteropServices.Marshal.FreeCoTaskMem(pPath); return s; } else return string.Empty; } private static string ResolveStandardKnownFolders( string knowID ) { if ( knowID.StartsWith("knownfolder:") ) { return getpathKnown(new Guid(knowID.Substring(12))); } else { return knowID; } } private static Win7Library GetLibraryInternalFolders( string libraryXmlPath ) { Win7Library newLibrary = new Win7Library(); //The Name of a Library is just its file name without the extension newLibrary.Name = System.IO.Path.GetFileNameWithoutExtension(libraryXmlPath); List folderpaths = new List(); System.Xml.XmlDocument xmlDoc = new System.Xml.XmlDocument(); //* create an xml document object. xmlDoc.Load(libraryXmlPath); //* load the library as an xml doc. //Grab all the URL tags in the document, //these point toward the folders contained in the library. System.Xml.XmlNodeList directories = xmlDoc.GetElementsByTagName("url"); foreach ( System.Xml.XmlNode x in directories ) { //Special folders use windows7 Know folders GUIDs instead //of full file paths, so we have to resolve them folderpaths.Add(ResolveStandardKnownFolders(x.InnerText)); } newLibrary.Folders = folderpaths.ToArray(); return newLibrary; } 

希望这有助于将来的某个人！
