FileRandomAccessStream.WriteAsync(IBuffer) 方法

定義

命名空間:

Windows.Storage.Streams

以非同步方式將資料寫入檔案。

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

非同步寫入器作業寫入的緩衝區。

傳回
