Barrier.Dispose Method

Releases all resources used by the current instance of the Barrier class.

Namespace:  System.Threading
Assembly:  System (in System.dll)

public void Dispose()




The method was invoked from within a post-phase action.

Call Dispose when you are finished using the Barrier. The Dispose method leaves the Barrier in an unusable state. After calling Dispose, you must release all references to the Barrier so the garbage collector can reclaim the memory that the Barrier was occupying.

For more information, see Cleaning Up Unmanaged Resources and Implementing a Dispose Method.


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