function copyAsync(source, destination)

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

參數

source: IInputStream

要從中複製資料的資料流程。

destination: IOutputStream

要複製資料的資料流程。

傳回

IAsyncOperationWithProgress<UInt64,UInt64>

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

IAsyncOperationWithProgress<uint64_t,uint64_t>

位元組寫入器作業。第一個整數代表寫入的位元組數目。第二個整數代表寫入作業的進度。
