Definisi

Ruang nama:

Windows.Storage.Streams

Menyalin aliran sumber ke aliran tujuan dan menunggu operasi penyalinan selesai.

public:
 static IAsyncOperationWithProgress<unsigned long long, unsigned long long> ^ CopyAndCloseAsync(IInputStream ^ source, IOutputStream ^ destination);

/// [Windows.Foundation.Metadata.RemoteAsync]
 static IAsyncOperationWithProgress<uint64_t, uint64_t> CopyAndCloseAsync(IInputStream const& source, IOutputStream const& destination);

[Windows.Foundation.Metadata.RemoteAsync]
public static IAsyncOperationWithProgress<ulong,ulong> CopyAndCloseAsync(IInputStream source, IOutputStream destination);

function copyAndCloseAsync(source, destination)

Public Shared Function CopyAndCloseAsync (source As IInputStream, destination As IOutputStream) As IAsyncOperationWithProgress(Of ULong, ULong)

Parameter

source

IInputStream

Aliran untuk menyalin data.

destination

IOutputStream

Aliran untuk menyalin data.

Mengembalikan

IAsyncOperationWithProgress<UInt64,UInt64>

Windows.Foundation.IAsyncOperationWithProgress<unsigned long long,unsigned long long>

IAsyncOperationWithProgress<uint64_t,uint64_t>

Operasi penulis byte. Bilangan bulat pertama menunjukkan jumlah byte yang ditulis. Bilangan bulat kedua mewakili kemajuan operasi tulis.

Atribut

RemoteAsyncAttribute

Keterangan

Metode CopyAndCloseAsync mirip dengan CopyAsync tetapi juga memanggil dan menunggu FlushAsync dan Tutup pada aliran output sebelum operasi asinkronnya selesai.
