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