Parameters

buffer

An array of bytes. This method copies count bytes from buffer to the current stream.

offset

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

count

The number of bytes to be written to the current stream.

Exceptions

Type	Reason
ArgumentException	(offset + count ) is greater than the length of buffer.
ArgumentNullException	buffer is null.
ArgumentOutOfRangeException	offset or count is negative.
System.IO.IOException	An I/O error occurred.
NotSupportedException	The stream does not support writing.
ObjectDisposedException	The stream is closed.

Remarks

Use the Stream.CanWrite property to determine whether the current instance supports writing. Use the Stream.WriteAsync(Byte[], int, int) method to write asynchronously to the current stream.

If the write operation is successful, the position within the stream advances by the number of bytes written. If an exception occurs, the position within the stream remains unchanged.
