If a class derived from Stream does not support reading, calls to the Read, ReadByte, BeginRead, EndRead, and the Peek methods of StreamReader, StringReader, and TextReader throw a NotSupportedException.

If the stream is closed, this property returns false.

This code example is part of a larger example provided for the BufferedStream class.

if(bufStream.CanRead)
{
    ReceiveData(netStream, bufStream);
}

if ( bufStream.get_CanRead()  ) {
    ReceiveData(netStream, bufStream);
}
