Esempio

Nell'esempio di codice seguente viene visualizzata una stringa originale, le stringhe restituite dal ToString metodo per le chiavi di ordinamento senza distinzione tra maiuscole e minuscole e senza distinzione tra maiuscole e minuscole e i dati delle chiavi di ordinamento senza distinzione tra maiuscole e minuscole.

Commenti

Il valore restituito è la concatenazione della stringa "SortKey -", l'identificatore delle impostazioni cultura e le opzioni di confronto dell'oggetto corrente SortKey e il valore della OriginalString proprietà.

Questo metodo esegue l'override di Object.ToString.
