Writes a byte to the current position in the stream and advances the position within the stream by one byte.
Assemblies: mscorlib (in mscorlib.dll)
System.IO (in System.IO.dll)
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.
