Parameters

buffer

A byte array containing the data to write.

offset

A int that specifies the zero based byte offset in buffer at which to begin copying bytes to the current stream.

count

A int that specifies 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

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

Operation

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.
