DelegatingStream.WriteAsync Method (Byte[], Int32, Int32, CancellationToken)

DelegatingStreamWriteAsync Method (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.

Syntax

Copy

public override Task WriteAsync(
	byte[] buffer,
	int offset,
	int count,
	CancellationToken cancellationToken
)

Public Overrides Function WriteAsync ( 
	buffer As Byte(),
	offset As Integer,
	count As Integer,
	cancellationToken As CancellationToken
) As Task

abstract WriteAsync : 
        buffer : byte[] * 
        offset : int * 
        count : int * 
        cancellationToken : CancellationToken -> Task 
override WriteAsync : 
        buffer : byte[] * 
        offset : int * 
        count : int * 
        cancellationToken : CancellationToken -> Task

Parameters

buffer: Type: SystemByte
The buffer to write data from.
offset: Type: SystemInt32
The zero-based byte offset in buffer from which to begin copying bytes to the stream.
count: Type: SystemInt32
The maximum number of bytes to write.
cancellationToken: Type: System.ThreadingCancellationToken
The token to monitor for cancellation requests. The default value is None.

Return Value

Type: Task
A task that represents the asynchronous write operation.

Exceptions

Exception	Condition
ArgumentNullException	buffer is null.
ArgumentOutOfRangeException	offset or count is negative.
ArgumentException	The sum of offset and count is larger than the buffer length.
NotSupportedException	The stream does not support writing.
ObjectDisposedException	The stream has been disposed.
InvalidOperationException	The stream is currently in use by a previous write operation.
