WindowsIdentity.User Property

Note: This property is new in the .NET Framework version 2.0.

Gets the security identifier (SID) for the user.

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

[ComVisibleAttribute(false)] 
public SecurityIdentifier User { get; }
/** @property */
public SecurityIdentifier get_User ()

public function get User () : SecurityIdentifier

Property Value

A SecurityIdentifier object for the user.

The SID uniquely identifies a user or group on all Windows NT implementations.

NoteNote

   The WindowsIdentity object returned by the GetAnonymous method is not the same as the Windows anonymous user. This property gets a null reference (Nothing in Visual Basic) for an anonymous user represented by the WindowsIdentity object returned by the GetAnonymous method; it does not get the SID representing an anonymous Windows user.

The following code example shows the use of the User property to display the security identifier for the user. This code example is part of a larger example provided for the WindowsIdentity class.

WindowsIdentity windowsIdentity = new WindowsIdentity(logonToken);

WindowsIdentity windowsIdentity = new WindowsIdentity(logonToken);

Windows 2000 SP4, Windows Millennium Edition, Windows Server 2003, Windows XP Media Center Edition, Windows XP Professional x64 Edition, Windows XP SP2, Windows XP Starter Edition
