使用 角色(用户)模拟 方式访问共享文件后怎么打开文件

[待解决问题]
主要使用了 advapi32.dll 和 kernel32.dll 来进行用户模拟, 可以对文件进行复制操作(比如将共享文件复制到本地磁盘 D), 但是无法直接打开任何共享文件, 如 .jpg 和 .doc
示例 : Process.Start(@"\\192.168.7.99\testpath\测试目录\测试文档.doc");
执行上述代码会报错, 登录失败: 未知的用户名或错误密码
以下为模拟用户代码
public class IdentityScope : IDisposable { // obtains user token [DllImport("advapi32.dll", SetLastError = true)] static extern bool LogonUser(string pszUsername, string pszDomain, string pszPassword, int dwLogonType, int dwLogonProvider, ref IntPtr phToken); // closes open handes returned by LogonUser [DllImport("kernel32.dll", CharSet = CharSet.Auto)] extern static bool CloseHandle(IntPtr handle); [DllImport("Advapi32.DLL")] static extern bool ImpersonateLoggedOnUser(IntPtr hToken); [DllImport("Advapi32.DLL")] static extern bool RevertToSelf(); const int LOGON32_PROVIDER_DEFAULT = 0; const int LOGON32_LOGON_NEWCREDENTIALS = 9;//域控中的需要用:Interactive = 2 private bool disposed; public IdentityScope(string sUsername, string sPassword, string sDomain) { // initialize tokens IntPtr pExistingTokenHandle = new IntPtr(0); IntPtr pDuplicateTokenHandle = new IntPtr(0); try { // get handle to token bool bImpersonated = LogonUser(sUsername, sDomain, sPassword, LOGON32_LOGON_NEWCREDENTIALS, LOGON32_PROVIDER_DEFAULT, ref pExistingTokenHandle); if (true == bImpersonated) { if (!ImpersonateLoggedOnUser(pExistingTokenHandle)) { int nErrorCode = Marshal.GetLastWin32Error(); throw new Exception("ImpersonateLoggedOnUser error;Code=" + nErrorCode); } } else { int nErrorCode = Marshal.GetLastWin32Error(); throw new Exception("LogonUser error;Code=" + nErrorCode); } } finally { // close handle(s) if (pExistingTokenHandle != IntPtr.Zero) CloseHandle(pExistingTokenHandle); if (pDuplicateTokenHandle != IntPtr.Zero) CloseHandle(pDuplicateTokenHandle); } } protected virtual void Dispose(bool disposing) { if (!disposed) { RevertToSelf(); disposed = true; } } public void Dispose() { Dispose(true); } }
