Overloads

WriteAsync(ReadOnlyMemory<Byte>, CancellationToken)

Asynchronously writes a span of bytes to the current stream, advances the current position within this stream by the number of bytes written, and monitors cancellation requests.
WriteAsync(Byte[], Int32, Int32, CancellationToken)

Asynchronously writes a sequence of bytes to the current stream, advances the current position within this stream by the number of bytes written, and monitors cancellation requests.

WriteAsync(ReadOnlyMemory<Byte>, CancellationToken)

Asynchronously writes a span of bytes to the current stream, advances the current position within this stream by the number of bytes written, and monitors cancellation requests.

public override System.Threading.Tasks.ValueTask WriteAsync (ReadOnlyMemory<byte> buffer, System.Threading.CancellationToken cancellationToken = default);
override this.WriteAsync : ReadOnlyMemory<byte> * System.Threading.CancellationToken -> System.Threading.Tasks.ValueTask
Public Overrides Function WriteAsync (buffer As ReadOnlyMemory(Of Byte), Optional cancellationToken As CancellationToken = Nothing) As ValueTask

Parameters

buffer
ReadOnlyMemory<Byte>

The buffer to write data from.

cancellationToken
CancellationToken

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

Returns

ValueTask

A task that represents the asynchronous write operation.

Remarks

If an exception occurs during the write operation, it will be set as the Task.Exception of the property of the returned task.

Applies to

WriteAsync(Byte[], Int32, Int32, CancellationToken)

Asynchronously writes a sequence of bytes to the current stream, advances the current position within this stream by the number of bytes written, and monitors cancellation requests.

public:
 override System::Threading::Tasks::Task ^ WriteAsync(cli::array <System::Byte> ^ buffer, int offset, int count, System::Threading::CancellationToken cancellationToken);
public override System.Threading.Tasks.Task WriteAsync (byte[] buffer, int offset, int count, System.Threading.CancellationToken cancellationToken);
[System.Runtime.InteropServices.ComVisible(false)]
public override System.Threading.Tasks.Task WriteAsync (byte[] buffer, int offset, int count, System.Threading.CancellationToken cancellationToken);
override this.WriteAsync : byte[] * int * int * System.Threading.CancellationToken -> System.Threading.Tasks.Task
[<System.Runtime.InteropServices.ComVisible(false)>]
override this.WriteAsync : byte[] * int * int * System.Threading.CancellationToken -> System.Threading.Tasks.Task
Public Overrides Function WriteAsync (buffer As Byte(), offset As Integer, count As Integer, cancellationToken As CancellationToken) As Task

Parameters

buffer
Byte[]

The buffer to write data from.

offset
Int32

The zero-based byte offset in buffer from which to begin copying bytes to the stream.

count
Int32

The maximum number of bytes to write.

cancellationToken
CancellationToken

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

Returns

Task

A task that represents the asynchronous write operation.

Attributes
ComVisibleAttribute

Remarks

If an exception occurs during the write operation, it will be set as the Task.Exception of the property of the returned task.
