- value
- Byte[]
Matrice di byte.
- startIndex
- Int32
Posizione iniziale all'interno di value.
Restituisce
Stringa di coppie esadecimali separate da trattini, dove ogni coppia rappresenta l'elemento corrispondente in una sottomatrice di value, ad esempio "7F-2C-4A-00".
Eccezioni
value è null.
startIndexè minore di zero o maggiore della lunghezza di value meno 1.
Esempio
L'esempio di codice seguente converte la parte di una Byte matrice a partire dall'oggetto specificato startIndex in un String con il ToString metodo .

Commenti
Gli elementi dalla posizione startIndex della matrice alla fine della matrice vengono convertiti.
Si applica a
ToString(Byte[], Int32, Int32)
- Source:
- BitConverter.cs
- Source:
- BitConverter.cs
- Source:
- BitConverter.cs
Converte il valore numerico di ogni elemento di una sottomatrice specificata di byte nella relativa rappresentazione di stringa esadecimale equivalente.
public:
static System::String ^ ToString(cli::array <System::Byte> ^ value, int startIndex, int length);public static string ToString (byte[] value, int startIndex, int length);static member ToString : byte[] * int * int -> stringPublic Shared Function ToString (value As Byte(), startIndex As Integer, length As Integer) As StringParametri
- value
- Byte[]
Matrice di byte che include i byte da convertire.
- startIndex
- Int32
Posizione iniziale all'interno di value.
- length
- Int32
Numero di elementi della matrice di value da convertire.
Restituisce
Stringa di coppie esadecimali separate da trattini, dove ogni coppia rappresenta l'elemento corrispondente in una sottomatrice di value, ad esempio "7F-2C-4A-00".
Eccezioni
value è null.
startIndex o length è minore di zero.
-oppure-
startIndex è maggiore di zero ed è maggiore o uguale alla lunghezza di value.
La combinazione di startIndex e di length non specifica una posizione all'interno di value, vale a dire che il parametro startIndex è maggiore della lunghezza di value meno il parametro length.
Esempio
Nell'esempio seguente viene usato il ToString metodo per convertire una parte di una matrice di byte, a partire dall'oggetto specificato e con l'oggetto specificato startIndexlengthin una stringa.
