Examples

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

if ( bufStream->CanRead )
{
   Client::ReceiveData( netStream, bufStream );
}

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

if bufStream.CanRead then
    receiveData netStream bufStream

If bufStream.CanRead Then
    ReceiveData(netStream, bufStream)
End If

Remarks

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.
