StreamedFileDataRequest.WriteAsync(IBuffer) 方法

定義

命名空間:

Windows.Storage

將資料從緩衝區寫入至目前的資料流程。

public:
 virtual IAsyncOperationWithProgress<unsigned int, unsigned int> ^ WriteAsync(IBuffer ^ buffer) = WriteAsync;

IAsyncOperationWithProgress<uint32_t, uint32_t> WriteAsync(IBuffer const& buffer);

public IAsyncOperationWithProgress<uint,uint> WriteAsync(IBuffer buffer);

function writeAsync(buffer)

Public Function WriteAsync (buffer As IBuffer) As IAsyncOperationWithProgress(Of UInteger, UInteger)

參數

buffer

IBuffer

包含要寫入之資料的緩衝區。

傳回

IAsyncOperationWithProgress<UInt32,UInt32>

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

IAsyncOperationWithProgress<uint32_t,uint32_t>

當這個方法完成時，它會傳回寫入資料流程 (類型 UInt32) 的位元組數目。 如果應用程式指定要監視進度的函式，該函式會接收目前所寫入 (類型 UInt32) 位元組數目。
