Poznámky

Převedou se prvky z pozice startIndex pole na konec pole.

Platí pro

ToString(Byte[], Int32, Int32)

Zdroj:
BitConverter.cs
Zdroj:
BitConverter.cs
Zdroj:
BitConverter.cs

Převede číselnou hodnotu každého prvku zadaného podarray bajtů na jeho ekvivalentní šestnáctkové řetězcové vyjádření.

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 -> string
Public Shared Function ToString (value As Byte(), startIndex As Integer, length As Integer) As String

Parametry

value
Byte[]

Pole bajtů, které zahrnuje bajty, které chcete převést.

startIndex
Int32

Počáteční pozice v rámci value.

length
Int32

Počet prvků pole, které se mají value převést.

Návraty

String

Řetězec šestnáctkových párů oddělených spojovníky, kde každý pár představuje odpovídající prvek v podadrech ; valuenapříklad "7F-2C-4A-00".

Výjimky

ArgumentNullException

value je null.

ArgumentOutOfRangeException

startIndex nebo length je menší než nula.

-nebo-

startIndexje větší než nula a je větší než nebo rovna délce .value

ArgumentException

Kombinace startIndex a length neurčovala pozici v ; valueto startIndex znamená, že parametr je větší než délka value parametru length minus parametr.

Příklady

Následující příklad používá metodu ToString k převodu části pole bajtů počínaje zadaným startIndex a zadaným lengthřetězcem na řetězec.
