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