I metodi GetLowerBound e GetUpperBound possono determinare se il valore di index non è compreso nei limiti.The GetLowerBound and GetUpperBound methods can determine whether the value of index is out of bounds.

Per ulteriori informazioni sulle conversioni, vedere Convert.For more information about conversions, see Convert.

Questo metodo è un'operazione O (1).This method is an O(1) operation.

Nota

Se SetValue viene usato per assegnare null a un elemento di una matrice di tipi valore, tutti i campi dell'elemento vengono inizializzati su zero.If SetValue is used to assign null to an element of an array of value types, all fields of the element are initialized to zero. Il valore dell'elemento non è un riferimento null e non è possibile trovarlo cercando un riferimento null.The value of the element is not a null reference, and cannot be found by searching for a null reference.

I metodi GetLowerBound e GetUpperBound possono determinare se il valore di index non è compreso nei limiti.The GetLowerBound and GetUpperBound methods can determine whether the value of index is out of bounds.

Questo metodo è un'operazione O (1).This method is an O(1) operation.

Nota

Se SetValue viene usato per assegnare null a un elemento di una matrice di tipi valore, tutti i campi dell'elemento vengono inizializzati su zero.If SetValue is used to assign null to an element of an array of value types, all fields of the element are initialized to zero. Il valore dell'elemento non è un riferimento null e non è possibile trovarlo cercando un riferimento null.The value of the element is not a null reference, and cannot be found by searching for a null reference.

I metodi GetLowerBound e GetUpperBound possono determinare se uno degli indici è fuori limite.The GetLowerBound and GetUpperBound methods can determine whether any of the indexes is out of bounds.

Per ulteriori informazioni sulle conversioni, vedere Convert.For more information about conversions, see Convert.

Questo metodo è un'operazione O (1).This method is an O(1) operation.

Nota

Se SetValue viene usato per assegnare null a un elemento di una matrice di tipi valore, tutti i campi dell'elemento vengono inizializzati su zero.If SetValue is used to assign null to an element of an array of value types, all fields of the element are initialized to zero. Il valore dell'elemento non è un riferimento null e non è possibile trovarlo cercando un riferimento null.The value of the element is not a null reference, and cannot be found by searching for a null reference.

L'oggetto Array corrente non ha esattamente tre dimensioni.The current Array does not have exactly three dimensions.

Non è possibile eseguire il cast di value al tipo di elemento dell'oggetto Array corrente.value cannot be cast to the element type of the current Array.

index1 o index2 o index3 non è compreso nell'intervallo di indici validi per la dimensione corrispondente dell'oggetto Array corrente.index1 or index2 or index3 is outside the range of valid indexes for the corresponding dimension of the current Array.
