InputStreamOverStream.ReadAsync(IBuffer, UInt32, InputStreamOptions) Método

Definição

Namespace:

Windows.Storage.Streams

Retorna um objeto de leitor de bytes assíncrono.

public:
 virtual IAsyncOperationWithProgress<IBuffer ^, unsigned int> ^ ReadAsync(IBuffer ^ buffer, unsigned int count, InputStreamOptions options) = ReadAsync;

IAsyncOperationWithProgress<IBuffer, uint32_t> ReadAsync(IBuffer const& buffer, uint32_t const& count, InputStreamOptions const& options);

public IAsyncOperationWithProgress<IBuffer,uint> ReadAsync(IBuffer buffer, uint count, InputStreamOptions options);

function readAsync(buffer, count, options)

Public Function ReadAsync (buffer As IBuffer, count As UInteger, options As InputStreamOptions) As IAsyncOperationWithProgress(Of IBuffer, UInteger)

Parâmetros

buffer

IBuffer

count

UInt32

unsigned int

uint32_t

O número de bytes a serem lidos que é menor ou igual ao valor capacidade .

options

InputStreamOptions

Especifica o tipo da operação de leitura assíncrona.

Retornos

IAsyncOperationWithProgress<IBuffer,UInt32>

Windows.Foundation.IAsyncOperationWithProgress<Windows.Storage.Streams.IBuffer,unsigned int>

IAsyncOperationWithProgress<IBuffer,uint32_t>

A operação assíncrona.
