 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)

参数
