Public Shared Function CopyToAsync (source As Stream, destination As Stream, count As Nullable(Of Long), cancel As CancellationToken) As Task

Parameters

source

Stream

The stream from which the contents will be copied.

destination

Stream

The stream to which the contents of the current stream will be copied.

count

Nullable<Int64>

The count of bytes to be copied.

cancel

CancellationToken

The token to monitor for cancellation requests. The default value is None.

Returns

Task

A task that represents the asynchronous copy operation.

CopyToAsync(Stream, Stream, Nullable<Int64>, Int32, CancellationToken)

Asynchronously reads the given number of bytes from the source stream and writes them to another stream, using a specified buffer size.

public:
 static System::Threading::Tasks::Task ^ CopyToAsync(System::IO::Stream ^ source, System::IO::Stream ^ destination, Nullable<long> count, int bufferSize, System::Threading::CancellationToken cancel);

public static System.Threading.Tasks.Task CopyToAsync (System.IO.Stream source, System.IO.Stream destination, long? count, int bufferSize, System.Threading.CancellationToken cancel);

static member CopyToAsync : System.IO.Stream * System.IO.Stream * Nullable<int64> * int * System.Threading.CancellationToken -> System.Threading.Tasks.Task

Public Shared Function CopyToAsync (source As Stream, destination As Stream, count As Nullable(Of Long), bufferSize As Integer, cancel As CancellationToken) As Task

Parameters

source

Stream

The stream from which the contents will be copied.

destination

Stream

The stream to which the contents of the current stream will be copied.

count

Nullable<Int64>

The count of bytes to be copied.

bufferSize

Int32

The size, in bytes, of the buffer. This value must be greater than zero. The default size is 4096.

cancel

CancellationToken

The token to monitor for cancellation requests. The default value is None.

Returns

Task

A task that represents the asynchronous copy operation.
