File.AppendAllBytesAsync Method

Definition

Overloads

AppendAllBytesAsync(String, Byte[], CancellationToken)

Asynchronously appends the specified byte array to the end of the file at the given path.

If the file doesn't exist, this method creates a new file. If the operation is canceled, the task will return in a canceled state.

AppendAllBytesAsync(String, ReadOnlyMemory<Byte>, CancellationToken)

Asynchronously appends the specified byte array to the end of the file at the given path.

If the file doesn't exist, this method creates a new file. If the operation is canceled, the task will return in a canceled state.

AppendAllBytesAsync(String, Byte[], CancellationToken)

Source:
File.cs

Asynchronously appends the specified byte array to the end of the file at the given path.

If the file doesn't exist, this method creates a new file. If the operation is canceled, the task will return in a canceled state.

public static System.Threading.Tasks.Task AppendAllBytesAsync (string path, byte[] bytes, System.Threading.CancellationToken cancellationToken = default);
static member AppendAllBytesAsync : string * byte[] * System.Threading.CancellationToken -> System.Threading.Tasks.Task
Public Shared Function AppendAllBytesAsync (path As String, bytes As Byte(), Optional cancellationToken As CancellationToken = Nothing) As Task

Parameters

path
String

The file to append to.

bytes
Byte[]

The bytes to append to the file.

cancellationToken
CancellationToken

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

Returns

A task that represents the asynchronous append operation.

Exceptions

path or bytes is null.

path is empty.

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