SymmetricAlgorithm.GenerateIV Method

When overridden in a derived class, generates a random initialization vector (IV) to use for the algorithm.

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

public abstract void GenerateIV()

In general, there is no reason to use this method, because CreateEncryptor() or CreateEncryptor(null, null) automatically generates both an initialization vector and a key. However, you may want to use the GenerateIV method to reuse a symmetric algorithm instance with a different initialization vector.
