目录访问共享C#怎么访问共享目录
本文是一篇关于目录访问共享的帖子
用C#访问共享目录老是涌现权限问题,让人很头疼,研究了良久找到一种方法,贴上代码:
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); } }
通过IdentityScope传入目标机器的IP,用户名和密码就能够访问到共享目录了。
如何使用如下:
using (IdentityScope iss = new IdentityScope(targetLoginName, targetPassword,targetIP)) { //你的代码 }
文章结束给大家分享下程序员的一些笑话语录:
某程序员对书法十分感兴趣,退休后决定在这方面有所建树。花重金购买了上等的文房四宝。一日突生雅兴,一番磨墨拟纸,并点上了上好的檀香,颇有王羲之风 范,又具颜真卿气势,定神片刻,泼墨挥毫,郑重地写下一行字:hello world.
