.NET Framework Class Library

WindowsIdentity Constructor (String)

Namespace: System.Security.Principal
Assembly: mscorlib (in mscorlib.dll)

Syntax

Visual Basic (Declaration)

Public Sub New ( _
    sUserPrincipalName As String _
)

Visual Basic (Usage)

Dim sUserPrincipalName As String

Dim instance As New WindowsIdentity(sUserPrincipalName)

public WindowsIdentity(
    string sUserPrincipalName
)

Visual C++

public:
WindowsIdentity(
    String^ sUserPrincipalName
)

JScript

public function WindowsIdentity(
    sUserPrincipalName : String
)

Parameters

sUserPrincipalName: Type: System..::.String
The UPN for the user on whose behalf the code is running.

Exceptions

Exception	Condition
UnauthorizedAccessException	Windows returned the Windows NT status code STATUS_ACCESS_DENIED.
OutOfMemoryException	There is insufficient memory available.
SecurityException	The caller does not have the correct permissions.

Remarks

The UPN identified in sUserPrincipalName is used to retrieve a token for that user through the Win32 API LsaLogonUser function. In turn that token is used to identify the user. An exception might be returned due to the inability to log on using the supplied UPN.

Note:
This constructor is intended for use on computers joined only to Windows Server 2003 domains. An exception is thrown for other domain types.
