Releases all resources used by the current instance of the RegistryKey class.
Assembly: mscorlib (in mscorlib.dll)
Call Dispose when you are finished using the RegistryKey. The Dispose method leaves the RegistryKey in an unusable state. After calling Dispose, you must release all references to the RegistryKey so the garbage collector can reclaim the memory that the RegistryKey was occupying.
