WindowsImpersonationContext Class

Represents the Windows user prior to an impersonation operation.

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

public class WindowsImpersonationContext implements IDisposable

This class reverts a user's identity after the user impersonates another user.

Notes to Implementers:

Because Microsoft Windows 98 and Windows Millennium Edition platforms do not have users or user tokens, impersonation cannot take place on those platforms.

The following example demonstrates how to impersonate a user and then revert to the original identity.

No code example is currently available or this language may not be supported.
