IsolatedStorageFileStream.WriteAsync Method

Definition

Overloads

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

Asynchronously writes a block of bytes to the isolated storage file stream object using data read from a buffer consisting of a byte array.

WriteAsync(ReadOnlyMemory<Byte>, CancellationToken)

Asynchronously writes a block of bytes to the isolated storage file stream object using data read from a buffer consisting of a read-only byte memory range.

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

Asynchronously writes a block of bytes to the isolated storage file stream object using data read from a buffer consisting of a 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

Parameters

buffer
Byte[]

The byte array from which to copy bytes to the current isolated storage file stream.

offset
Int32

The byte offset in buffer from which to begin.

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.

Remarks

If the write operation is successful, the current position of the IsolatedStorageFileStream object is advanced by the number of bytes written. If an exception occurs, the current position of the IsolatedStorageFileStream object is unchanged.

WriteAsync(ReadOnlyMemory<Byte>, CancellationToken)

Asynchronously writes a block of bytes to the isolated storage file stream object using data read from a buffer consisting of a read-only 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

Parameters

buffer
ReadOnlyMemory<Byte>

The read-only byte memory from which to copy bytes to the current isolated storage file stream.

cancellationToken
CancellationToken

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

Returns

A task that represents the asynchronous write operation.
