网络文件夹浏览器服务
在网上有一些类似的问题 – 甚至在这里有一些问题，但即使这些问题似乎很高兴，我找不到真正做到我需要的东西。
我正在尝试将远程目录浏览function添加到基于Web的管理控制面板（基于Intranet）。
此时我不需要担心安全性，因为这是在其他地方处理的。
为此，我使用的Web服务接受服务器名称和共享/文件夹路径作为参数。 我只需要它返回此路径的子目录，如果有的话。
听起来不是那么难，是吗？ 嗯，这是（至少对我来说！）
我需要帮助的唯一一点是实际生成服务器和提供的路径的目录列表。
所有的帮助表示赞赏，但请不要只是链接到一个网站，因为我可能已经看到它但未能找到一个有效的解决方案; 其中大多数甚至似乎都没有试图做标题所暗示的。 一些解释也会有所帮助！
干杯
您可以使用Interop使用此处描述的方法。
我对代码做了一些修改以得出这个。 我没有对此进行过广泛的测试，所以它可能有错误，但它应该让你开始。
private List GetSubDirectories(string serverName, string folderPath) { List subDirectories = new List (); string folder_path = Path.Combine(serverName, folderPath); IntPtr INVALID_HANDLE_VALUE = new IntPtr(-1); WIN32_FIND_DATA findData; IntPtr findHandle; findHandle = FindFirstFile(folder_path, out findData); if (findHandle == INVALID_HANDLE_VALUE) { int error = Marshal.GetLastWin32Error(); Console.WriteLine(error.ToString()); return null; } do { try { if ((findData.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY) == FILE_ATTRIBUTE_DIRECTORY) subDirectories.Add(findData.cFileName); } catch (Exception ex) { Console.WriteLine(ex.ToString()); } } while (FindNextFile(findHandle, out findData)); FindClose(findHandle); return subDirectories; } public const int FILE_ATTRIBUTE_DIRECTORY = 0x10; [DllImport("kernel32", SetLastError = true, CharSet = CharSet.Auto)] public static extern IntPtr FindFirstFile(string lpFileName, out WIN32_FIND_DATA lpFindFileData); [DllImport("kernel32", SetLastError = true, CharSet = CharSet.Auto)] public static extern bool FindNextFile(IntPtr hFindFile, out WIN32_FIND_DATA lpFindFileData); [DllImport("kernel32", SetLastError = true, CharSet = CharSet.Auto)] public static extern bool FindClose(IntPtr hFindFile); [StructLayout(LayoutKind.Sequential)] public struct FILETIME { public uint dwLowDateTime; public uint dwHighDateTime; }; [StructLayout(LayoutKind.Sequential, CharSet = CharSet.Auto)] public struct WIN32_FIND_DATA { public uint dwFileAttributes; public System.Runtime.InteropServices.ComTypes.FILETIME ftCreationTime; public System.Runtime.InteropServices.ComTypes.FILETIME ftLastAccessTime; public System.Runtime.InteropServices.ComTypes.FILETIME ftLastWriteTime; public uint nFileSizeHigh; public uint nFileSizeLow; public uint dwReserved0; public uint dwReserved1; [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 260)] public string cFileName; [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 14)] public string cAlternateFileName; } [DllImport("kernel32.dll", CharSet = CharSet.Auto)] public static extern bool CloseHandle(IntPtr handle); } 你可以这样称呼：
var subdirectories = GetSubDirectories(@"\\[serverName]", @"[folderPath]\*");
您必须按照MSDN添加“\ *”
在网络共享上，您可以使用以下forms的lpFileName：“\ Server \ Share *”。 但是，您不能使用指向共享本身的lpFileName; 例如，“\ Server \ Share”无效。
不确定我们是否能做到这一点。 我们有类似的问题，但最终通过提供共享路径（\ SERVERNAME \ FOLDER）解决了它。
最重要的Web服务应该使用具有访问目录的完全权限的帐户，否则与权限相关的exception将被抛出到调用客户端。
好吧，实际上它可以使用NetShareEnum Win32APIfunction完成 。
但这里是.NET包装类，用于枚举本地和远程计算机上的网络共享，并将本地文件路径转换为UNC路径。 请参阅文章网络共享和UNC路径 。
要枚举.NET中指定文件夹的子文件夹，您可以使用DirectoryInfo.EnumerateDirectories方法。
要枚举某些计算机的共享，如果隐藏的管理共享（如C$ ， ADMIN$ ， print$等）对您不重要或使用NetShareEnum枚举所有共享，则可以使用WNetEnumResource本机函数。
相应的代码可以是
