Converte o valor numérico de cada elemento de uma submatriz de bytes especificada em sua representação de cadeia de caracteres hexadecimal equivalente.

public:
 static System::String ^ ToString(cli::array <System::Byte> ^ value, int startIndex);
public static string ToString (byte[] value, int startIndex);
static member ToString : byte[] * int -> string
Public Shared Function ToString (value As Byte(), startIndex As Integer) As String

Parâmetros

value
Byte[]

Uma matriz de bytes.

startIndex
Int32

A posição inicial dentro de value.

Retornos

String

Uma cadeia de caracteres de pares hexadecimais separados por hifens, em que cada par representa o elemento correspondente de uma submatriz de value. Por exemplo, "7F-2C-4A-00".

Exceções

ArgumentNullException

value é null.

ArgumentOutOfRangeException

startIndex é menor que zero ou maior que o tamanho de value menos 1.

Exemplos

O exemplo de código a seguir converte a parte de uma Byte matriz começando no especificado startIndex em um String com o ToString método .

Comentários

Os elementos da posição startIndex da matriz até o final da matriz são convertidos.

Aplica-se a

ToString(Byte[], Int32, Int32)

Origem:
BitConverter.cs
Origem:
BitConverter.cs
Origem:
BitConverter.cs

Converte o valor numérico de cada elemento de uma submatriz de bytes especificada em sua representação de cadeia de caracteres hexadecimal 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 -> string
Public Shared Function ToString (value As Byte(), startIndex As Integer, length As Integer) As String

Parâmetros

value
Byte[]

Uma matriz de bytes que inclui os bytes a serem convertidos.

startIndex
Int32

A posição inicial dentro de value.

length
Int32

O número de elementos da matriz em value a serem convertidos.

Retornos

String

Uma cadeia de caracteres de pares hexadecimais separados por hifens, em que cada par representa o elemento correspondente de uma submatriz de value. Por exemplo, "7F-2C-4A-00".

Exceções

ArgumentNullException

value é null.

ArgumentOutOfRangeException

startIndex ou length é menor que zero.

- ou -

startIndex é maior que zero e é maior ou igual ao comprimento de value.

ArgumentException

A combinação de startIndex e length não especifica uma posição em value, ou seja, o parâmetro startIndex é maior que o comprimento de value menos o parâmetro length.

Exemplos

O exemplo a seguir usa o ToString método para converter parte de uma matriz de bytes, começando no especificado startIndex e com o especificado length, em uma cadeia de caracteres.

Comentários

Os length elementos da posição startIndex da matriz são convertidos. Se length for igual a zero, o método retornará String.Empty.

Aplica-se a
