Socket.IsBound Property
.NET Framework 3.0
Gets a value that indicates whether the Socket is bound to a specific local port.
Namespace: System.Net.Sockets
Assembly: System (in system.dll)
Assembly: System (in system.dll)
A socket is considered bound to a local port if it is explicitly bound by calling the Bind method, or implicitly bound by calling members like Connect, SendTo, or ReceiveFrom, which use an ephemeral local port (a free port greater than 1024, selected by the operating system.) Servers use the Bind method to bind to a well-known port so that clients may connect to them.
The following code example demonstrates the use of the IsBound property.
static void ConfigureTcpSocket(Socket tcpSocket) { // Don't allow another socket to bind to this port. tcpSocket.ExclusiveAddressUse = true; // The socket will linger for 10 seconds after // Socket.Close is called. tcpSocket.LingerState = new LingerOption (true, 10); // Disable the Nagle Algorithm for this tcp socket. tcpSocket.NoDelay = true; // Set the receive buffer size to 8k tcpSocket.ReceiveBufferSize = 8192; // Set the timeout for synchronous receive methods to // 1 second (1000 milliseconds.) tcpSocket.ReceiveTimeout = 1000; // Set the send buffer size to 8k. tcpSocket.SendBufferSize = 8192; // Set the timeout for synchronous send methods // to 1 second (1000 milliseconds.) tcpSocket.SendTimeout = 1000; // Set the Time To Live (TTL) to 42 router hops. tcpSocket.Ttl = 42; Console.WriteLine("Tcp Socket configured:"); Console.WriteLine(" ExclusiveAddressUse {0}", tcpSocket.ExclusiveAddressUse); Console.WriteLine(" LingerState {0}, {1}", tcpSocket.LingerState.Enabled, tcpSocket.LingerState.LingerTime); Console.WriteLine(" NoDelay {0}", tcpSocket.NoDelay); Console.WriteLine(" ReceiveBufferSize {0}", tcpSocket.ReceiveBufferSize); Console.WriteLine(" ReceiveTimeout {0}", tcpSocket.ReceiveTimeout); Console.WriteLine(" SendBufferSize {0}", tcpSocket.SendBufferSize); Console.WriteLine(" SendTimeout {0}", tcpSocket.SendTimeout); Console.WriteLine(" Ttl {0}", tcpSocket.Ttl); Console.WriteLine(" IsBound {0}", tcpSocket.IsBound); Console.WriteLine(""); }
