socket.available (socket closed)

[Dirk Reske]

Hello,

in msdn stands, that the socket.available property can fire a
SocketException when the remote machine has closed the connection.
why can?

I have to check the number of receivable bytes bevor I receive them, but
when remote closes the connection, it ends in an endless loop...
while(socket.Available < RequiredBytes) {}

how to solve?

thanks

has no sense. That is why exception is thrown.

the problem is, that no exception is thrown...

i have implemented a method GetPacket(Socket s) that should read data from
the socket, until a whole packet is received...
the socket are in blocking mode, because this runs in its own thread, so I
don't need asynchone operations....and the method should not return before
the whole packet is received.

and sometimes when I read the packet header, the socket.receive method
returns, before the whole header is received.
So i was looking for a way to ensure I can read the whole header.

I've solved it myself...
I receive the data in a loop until my required data is successfully
received...

thanks
