ArgumentNullException

value è null.

Esempio

Nell'esempio di codice seguente vengono illustrati i risultati di Equals quando vengono confrontati con oggetti diversi SortKey .

Due SortKey oggetti vengono considerati uguali se le relative KeyData proprietà sono uguali.

Questo metodo esegue l'override di Object.Equals.
