WaitHandle.Close Method

Releases all resources held by the current WaitHandle.

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

public virtual void Close()

This method is the public implementation of the IDisposable.Dispose method for the WaitHandle class and its derived classes. It provides a standard implementation that calls the Dispose(Boolean) overload with a true argument and then calls the GC.SuppressFinalize method. Call this method to release all resources held by an instance of WaitHandle or a derived class.

Once this method is called, references to the current instance cause undefined behavior.

NoteNote

Always call Close or Dispose() before you release your last reference to the WaitHandle. Otherwise, the resources it is using will not be freed.

Notes to Inheritors

You should override the Dispose(Boolean) method to release resources allocated in derived classes.
