BrotliStream.WriteAsync Method

Definition

Overloads

WriteAsync(ReadOnlyMemory<Byte>, CancellationToken)

Asynchronously writes compressed bytes to the underlying Brotli stream from the specified byte memory range.

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

Asynchronously writes compressed bytes to the underlying Brotli stream from the specified byte array.

WriteAsync(ReadOnlyMemory<Byte>, CancellationToken)

Source:
BrotliStream.Compress.cs
Source:
BrotliStream.Compress.cs
Source:
BrotliStream.Compress.cs

Asynchronously writes compressed bytes to the underlying Brotli stream from the specified byte memory range.

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 memory region to write data from.

cancellationToken
CancellationToken

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

Returns

A task that represents the asynchronous write operation.

Exceptions

The cancellation token was canceled. This exception is stored into the returned task.

Remarks

The `WriteAsync` method enables you to perform resource-intensive I/O operations without blocking the main thread. This performance consideration is particularly important in a Windows 8.x Store app or desktop app where a time-consuming stream operation can block the UI thread and make your app appear as if it is not working. The async methods are used in conjunction with the async and await keywords in Visual Basic and C#.

Use the CanWrite property to determine whether the current instance supports writing.

If the operation is canceled before it completes, the returned task contains the Canceled value for the Status property.

Source:

Asynchronously writes compressed bytes to the underlying Brotli stream from the specified byte array.

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);
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 that contains the data to compress.

offset
Int32

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

A task that represents the asynchronous write operation.

Exceptions

The cancellation token was canceled. This exception is stored into the returned task.

This method stores in the task it returns all non-usage exceptions that the method's synchronous counterpart can throw. If an exception is stored into the returned task, that exception will be thrown when the task is awaited. Usage exceptions, such as ArgumentException, are still thrown synchronously. For the stored exceptions, see the exceptions thrown by Write(Byte[], Int32, Int32).
