An attempt was made to change the Key property after hashing has begun.

This property is the public accessor for the KeyValue field.

The following code example demonstrates how to override the Key property to retrieve the key used in the current KeyedHashAlgorithm object. This code example is part of a larger example provided for the KeyedHashAlgorithm class.


Public Overrides Property Key() As Byte()
    Get
        Return CType(keyedCrypto.Key.Clone(), Byte())
    End Get
    Set(ByVal Value As Byte())
        keyedCrypto.Key = CType(Value.Clone(), Byte())
    End Set
End Property
