使用ImpersonateLoggedOnUser移动文件

我正在尝试移动文件，但是会出现此错误：

System.UnauthorizedAccessException：拒绝访问路径..
在System.IO .__ Error.WinIOError（Int32 errorCode，String maybeFullPath）
在System.IO .__ Error.WinIOError（）
在System.IO.FileInfo.MoveTo（String destFileName）

要移动文件，我有以下代码：

public void MssFile_Move (string ssPath, string ssDestinationDirectoryPath, string ssDomain, string ssUsername, string ssPassword, out string ssError_message) { IntPtr admin_token = IntPtr.Zero; ssError_message = ""; try { DoImpersonateLoggedOnUser( ssDomain , ssUsername , ssPassword , out ssError_message , out admin_token); FileInfo fi = new FileInfo(ssPath); //Destination Directory does not exist ? if ( !Directory.Exists(Path.GetDirectoryName(ssDestinationDirectoryPath))) Directory.CreateDirectory(Path.GetDirectoryName( ssDestinationDirectoryPath)); fi.MoveTo (ssDestinationDirectoryPath); DoRevertToSelf(ssDomain); } catch (System.Exception se) { int ret = Marshal.GetLastWin32Error(); ssError_message += "Win32Error: " + ret + "\n"; ssError_message += se.ToString(); } finally { if (admin_token != IntPtr.Zero) CloseHandle(admin_token); } } 

冒充我有：

 [DllImport("advapi32.DLL", SetLastError = true)] public static extern int LogonUser(string lpszUsername, string lpszDomain, string lpszPassword, int dwLogonType, int dwLogonProvider, out IntPtr phToken); [DllImport("advapi32.DLL")] public static extern bool ImpersonateLoggedOnUser(IntPtr hToken); //handle to token for logged-on user public void DoImpersonateLoggedOnUser ( string ssDomain , string ssUsername , string ssPassword , out string ssError_message , out IntPtr admin_token) { IntPtr phToken = IntPtr.Zero; admin_token = IntPtr.Zero; ssError_message = ""; if (ssDomain != "") { if (LogonUser(ssUsername, ssDomain, ssPassword, 9, 0, out phToken) != 0) { ImpersonateLoggedOnUser(phToken); } else { int nErrorCode = Marshal.GetLastWin32Error(); ssError_message = "Operation Failed, error: " + nErrorCode; } admin_token = phToken; } } 

如果我将文件夹/文件设置为权限所有人，它可以工作，但我不希望这样。 我究竟做错了什么？

用这段代码完成了它。

 [DllImport("advapi32.DLL", SetLastError = true)] public static extern int LogonUser( string lpszUsername, string lpszDomain, string lpszPassword, int dwLogonType, int dwLogonProvider, out IntPtr phToken); [DllImport("advapi32.DLL")] public static extern bool ImpersonateLoggedOnUser(IntPtr hToken); //handle to token for logged-on user [DllImport("advapi32.DLL")] public static extern bool RevertToSelf(); [DllImport("kernel32.dll")] public extern static bool CloseHandle(IntPtr hToken); enum LogonType { Interactive = 2, Network = 3, Batch = 4, Service = 5, Unlock = 7, NetworkClearText = 8, NewCredentials = 9 } enum LogonProvider { Default = 0, WinNT35 = 1, WinNT40 = 2, WinNT50 = 3 } int valid = LogonUser( ssUsername, ssDomain, ssPassword, (int)LogonType.Interactive, (int)LogonProvider.WinNT50, out admin_token); if (valid != 0) { using (WindowsImpersonationContext context = WindowsIdentity.Impersonate(admin_token)) { CloseHandle(admin_token); FileInfo fi = new FileInfo(ssPath); //Destination Directory does not exist ? if (!Directory.Exists(Path.GetDirectoryName(ssDestinationDirectoryPath))) Directory.CreateDirectory(Path.GetDirectoryName(ssDestinationDirectoryPath)); fi.CopyTo(ssDestinationDirectoryPath); fi.Delete(); } } 

Answer 2

有两种可能的冲突：是否允许模拟使用来删除源文件？

用户是否可以查看 ssDestinationDirectoryPath的完整路径？

我在文件移动方面遇到了很多麻烦，所以请尝试复制然后删除 。
