WindowsImpersonationContext::Dispose Method

Releases all resources used by the WindowsImpersonationContext.

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

virtual void Dispose() sealed



Call Dispose when you are finished using the WindowsImpersonationContext. The Dispose method leaves the WindowsImpersonationContext in an unusable state. After calling Dispose, you must release all references to the WindowsImpersonationContext so the garbage collector can reclaim the memory that the WindowsImpersonationContext was occupying. For more information, see Cleaning Up Unmanaged Resources and Implementing a Dispose Method.

Note: Always call Dispose before you release your last reference to the WindowsImpersonationContext. Otherwise, the resources it is using will not be freed until the garbage collector calls the WindowsImpersonationContext object's Finalize method.
