true if data is available on the stream to be read; otherwise, false.
Exceptions
The NetworkStream is closed.
The underlying Socket is closed.
Use the ErrorCode property to obtain the specific error code and refer to the Windows Sockets version 2 API error code documentation for a detailed description of the error.
Remarks
Use the DataAvailable property to determine if data is queued to be immediately read.
If DataAvailable is true, a call to Read returns immediately.
If the remote host shuts down or closes the connection, DataAvailable may throw a SocketException.
Note
Do not use DataAvailable to determine whether the transmission has ended. Even if there's no data available to be immediately read, the underlying socket may receive more data later.
