BufferedStream::ReadByte Method ()

 

Reads a byte from the underlying stream and returns the byte cast to an int, or returns -1 if reading from the end of the stream.

Namespace:   System.IO
Assembly:  mscorlib (in mscorlib.dll)

public:
virtual int ReadByte() override

Return Value

Type: System::Int32

The byte cast to an int, or -1 if reading from the end of the stream.

Exception Condition
IOException

An I/O error occurs, such as the stream being closed.

NotSupportedException

The stream does not support reading.

ObjectDisposedException

Methods were called after the stream was closed.

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.
