(Inherited from TcpConnection) | |
ToString |
The address and port number are the parameters which were passed into the constructor.
(Overrides TcpConnectionToString) | |
WaitForData |
Causes the currently executing thread to sleep until BytesAvailable > 0, or for a maximum of
maxTimeout milliseconds.
(Inherited from ConnectionA) | |
Write(BinaryReader) |
