Programming Pillars Inheritance Part 2 docsity.com Lecture Overview = Abstract classes docsity.com Abstract Classes (Using)  Define the implementation in the derived class  A derived class can inherit from an abstract class A derived class must implement all abstract members  (those declared as abstract)  A derived class can inherit members implemented in the abstract class docsity.com Abstract Classes (Example 1)  Cryptography uses standard algorithms to encrypt and decrypt messages  There are different cryptographic algorithms  DES, RC2, Rijndael, TripleDES  They all “work” the same way  They are all symmetric algorithms  The SymmetricAlgorithm class is the abstract class for all symmetric cryptographic algorithms docsity.com Abstract Classes (Example 1) OR ee ee ee om Ae SP ene etter eel ae File Edit View Tools Window — Help 4) How Dol + .NET Framework Class Library SymmetricaAlgorithm Class See Also Example Members & Collapse All yl Language Filter: All \> Represents the abstract base class from which all implementations of symmetric algorithms must inherit, Namespace: System.Security.Cryptography Assembly: mscorlib (in mscorlib.dll) -] Syntax ¥isual Basic (Declaration) <ComVisibleAttribute (True}> _ Public MustInherit Class SymmetricAlgorithm Implements IDisposable ¥isual Basic (Usage) Din instance As sSymmetricAlgorithn
