Reads a byte from the stream and advances the position within the stream by one byte, or returns -1 if at the end of the stream.
Assembly: mscorlib (in mscorlib.dll)
Use the CanRead property to determine whether the current instance supports reading.
Attempts to manipulate the stream after the stream has been closed could throw an ObjectDisposedException.Notes to Implementers
The default implementation on Stream creates a new single-byte array and then calls Read. 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 reads the buffer directly, avoiding the extra array allocation on every call.
