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

Namespace:   System.Security.Cryptography
Assembly:  mscorlib (in mscorlib.dll)

virtual void Dispose() sealed

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.

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


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