Edit

Copies a source stream to a destination stream and waits for the copy operation to complete.

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)

Parameters

source: IInputStream

The stream to copy data from.

destination: IOutputStream

The stream to copy data to.

Returns

IAsyncOperationWithProgress<UInt64,UInt64>

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

IAsyncOperationWithProgress<uint64_t,uint64_t>

The byte writer operation. The first integer represents the number of bytes written. The second integer represents the progress of the write operation.

Attributes: RemoteAsyncAttribute

Remarks

The CopyAndCloseAsync method is similar to CopyAsync but also calls and waits for FlushAsync and Close on the output stream before its asynchronous operation completes.
