asp.net访问网络路径方法(模拟用户登录)

核心代码：

[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ò控?中D的?需è要a用?:Interactive = 2 private bool disposed; /// <summary> /// 登?录? /// </summary> /// <param name="sUsername"&gt;用?户§名?</param> /// <param name="sDomain"&gt;域ò名?，?如?果?不?在ú域ò中D就í使1用?机ú器÷IP地?址·</param> /// <param name="sPassword"&gt;密ü码?</param> public IdentityScope(string sUsername,string sDomain,string sPassword) { // 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); }

}

第二个参数是域名，有域名的话写域名，没有域名写目标机器的IP就可以了
