Releases all resources used by the CriticalHandle.
Assembly: mscorlib (in mscorlib.dll)
Calling the Close or Dispose method allows the resources to be freed. Unlike the SafeHandle class, this will always happen immediately since there is no reference count to indicate that other threads are using this handle. Therefore, you must employ a synchronization mechanism to ensure it is safe to call the Dispose method. Although most classes that use the CriticalHandle class do not need to provide a finalizer, this is sometimes necessary (for example, to flush out file buffers or to write some data back into memory). In this case, the class can provide a finalizer that is guaranteed to run before the CriticalHandle critical finalizer runs.
Note Always call the Close or Dispose method before you release your last reference to the CriticalHandle object. Otherwise, the resources it is using will not be freed until the garbage collector calls the CriticalHandle object's Finalize method.
