Stream.WriteByte Method

Writes a byte to the current position in the stream and advances the position within the stream by one byte.

Namespace:  System.IO
Assembly:  mscorlib (in mscorlib.dll)
public virtual void WriteByte(
	byte value
)

Parameters

value
Type: System.Byte
The byte to write to the stream.
ExceptionCondition
IOException

An I/O error occurs.

NotSupportedException

The stream does not support writing, or the stream is already closed.

ObjectDisposedException

Methods were called after the stream was closed.

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

Notes to Implementers

The default implementation on Stream creates a new single-byte array and then calls Write. While this is formally correct, it is inefficient. Any stream with an internal buffer should override this method and provide a much more efficient version that writes to the buffer directly, avoiding the extra array allocation on every call.
