RijndaelManagedTransform.Dispose Method

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

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

public void Dispose()



Call Dispose when you are finished using the RijndaelManagedTransform. The Dispose method leaves the RijndaelManagedTransform in an unusable state. After calling Dispose, you must release all references to the RijndaelManagedTransform so the garbage collector can reclaim the memory that the RijndaelManagedTransform 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 RijndaelManagedTransform. Otherwise, the resources it is using will not be freed until the garbage collector calls the RijndaelManagedTransform object's Finalize method.
