傳回非同步位元組讀取器物件。
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)
參數
- buffer
- IBuffer
非同步讀取作業在其中放置讀取位元組的緩衝區。
- options
- InputStreamOptions
指定非同步讀取作業的類型。
