Спасибо. Я преобразую его в VB.net, чтобы другие пользователи не сталкивались с трудностями.Это класс, который мне нужно было добавить в мой проект
Public Class UserImpersonation
Const LOGON32_LOGON_INTERACTIVE = 2
Const LOGON32_LOGON_NETWORK = 3
Const LOGON32_LOGON_BATCH = 4
Const LOGON32_LOGON_SERVICE = 5
Const LOGON32_LOGON_UNLOCK = 7
Const LOGON32_LOGON_NETWORK_CLEARTEXT = 8
Const LOGON32_LOGON_NEW_CREDENTIALS = 9
Const LOGON32_PROVIDER_DEFAULT = 0
Const LOGON32_PROVIDER_WINNT35 = 1
Const LOGON32_PROVIDER_WINNT40 = 2
Const LOGON32_PROVIDER_WINNT50 = 3
Dim impersonationContext As WindowsImpersonationContext
Declare Function LogonUserA Lib "advapi32.dll" (ByVal lpszUsername As String, _
ByVal lpszDomain As String, _
ByVal lpszPassword As String, _
ByVal dwLogonType As Integer, _
ByVal dwLogonProvider As Integer, _
ByRef phToken As IntPtr) As Integer
Declare Auto Function DuplicateToken Lib "advapi32.dll" ( _
ByVal ExistingTokenHandle As IntPtr, _
ByVal ImpersonationLevel As Integer, _
ByRef DuplicateTokenHandle As IntPtr) As Integer
Declare Auto Function RevertToSelf Lib "advapi32.dll" () As Long
Declare Auto Function CloseHandle Lib "kernel32.dll" (ByVal handle As IntPtr) As Long
Public Function impersonateUser(ByVal userName As String, ByVal domain As String, ByVal password As String) As Boolean
Return impersonateValidUser(userName, domain, password)
End Function
Public Sub undoimpersonateUser()
undoImpersonation()
End Sub
Private Function impersonateValidUser(ByVal userName As String, ByVal domain As String, ByVal password As String) As Boolean
Dim tempWindowsIdentity As WindowsIdentity
Dim token As IntPtr = IntPtr.Zero
Dim tokenDuplicate As IntPtr = IntPtr.Zero
impersonateValidUser = False
If RevertToSelf() Then
If LogonUserA(userName, domain, password, LOGON32_LOGON_NEW_CREDENTIALS, LOGON32_PROVIDER_WINNT50, token) <> 0 Then
If DuplicateToken(token, 2, tokenDuplicate) <> 0 Then
tempWindowsIdentity = New WindowsIdentity(tokenDuplicate)
impersonationContext = tempWindowsIdentity.Impersonate()
If Not impersonationContext Is Nothing Then
impersonateValidUser = True
End If
End If
End If
End If
If Not tokenDuplicate.Equals(IntPtr.Zero) Then
CloseHandle(tokenDuplicate)
End If
If Not token.Equals(IntPtr.Zero) Then
CloseHandle(token)
End If
End Function
Private Sub undoImpersonation()
impersonationContext.Undo()
End Sub
End Class
, затем в своем контроллере я использую его как Be.St упоминает
<Authorize()> _
Function SearchUrlNewDir() As String
Dim impersonateUser As New UserImpersonation
impersonateUser.impersonateUser("username", "", "password.")
Dim di As DirectoryInfo = New DirectoryInfo("\\10.11.11.172\remfolder")
'Dim subFiles() As FileInfo = di.GetFiles()
Dim subFolders() As DirectoryInfo = di.GetDirectories()
impersonateUser.undoimpersonateUser()
Return ""
End Function
Этот класс можно использовать для того, чтобыдоступ к файлам или папкам на удаленных компьютерах через UNC, от asp.net до сервера samba linux, который не требует, чтобы имитатор находился в одном домене с этим сервером.
Множество спасибо
