WindowsPrincipal.IsInRole Method

Determines whether the current principal belongs to a specified Windows user group.

Name Description
WindowsPrincipal.IsInRole (Int32) Determines whether the current principal belongs to the Windows user group with the specified relative identifier (RID).
WindowsPrincipal.IsInRole (SecurityIdentifier) Determines whether the current principal belongs to the Windows user group with the specified security identifier (SID).
WindowsPrincipal.IsInRole (String) Determines whether the current principal belongs to the Windows user group with the specified name.
WindowsPrincipal.IsInRole (WindowsBuiltInRole) Determines whether the current principal belongs to the Windows user group with the specified WindowsBuiltInRole.

There are four overloads for this method. For performance reasons, the IsInRole(SecurityIdentifier) overload is strongly recommended.

NoteImportant:

The IsInRole method is not supported on Windows 98 or Windows Millennium Edition.
