Instantiates a new Socket object with a given endPoint instances address family, the SocketType.Stream, and ProtocolType.Tcp. Socket server received message: "Hi friends ?!" _ = await client.SendAsync(messageBytes, SocketFlags.None) Ĭonsole.WriteLine($"Socket client sent message: \"\"") Once the socket is connected, it can send and receive data from the server socket connection. With the endPoint object created, create a client socket to connect to the server. IPEndPoint ipEndPoint = new(ipAddress, 11_000) Īfter determining the address of the remote device and choosing a port to use for the connection, the app can establish a connection with the remote device. The following code combines the IP address for with a port number to create a remote endpoint for a connection. Other services can have registered port numbers in the range 1,024 to 65,535. For more information, see IANA: Service Name and Transport Protocol Port Number Registry). ![]() The Internet Assigned Numbers Authority (IANA) defines port numbers for common services. IPAddress ipAddress = ipHostInfo.AddressList įor manual testing and debugging purposes, you can typically use the GetHostEntryAsync method to get given the Dns.GetHostName() value to resolve the localhost name to an IP address. IPHostEntry ipHostInfo = await Dns.GetHostEntryAsync("") The following code gets an IPAddress containing the IP address for the server. In most cases, you can use the first address returned in the AddressList array. GetHostEntryAsync returns a Task that when awaited contains a list of addresses and aliases for the requested name. The GetHostEntryAsync method queries a DNS server to map a user-friendly domain name (such as "") to a numeric Internet address (such as 192.168.1.1). The Dns class provides domain-name services to apps that use TCP/IP internet services. A descendant of EndPoint is defined for each supported address family for the IP address family, the class is IPEndPoint. ![]() The combination of network address and service port is called an endpoint, which is represented in the. The network address identifies a specific network destination the port number identifies the specific service on that device to connect to. TCP/IP uses a network address and a service port number to uniquely identify a service. Before you can initiate a conversation through a Socket, you create a data pipe between your app and the remote destination. The IPEndPoint is constructed with an IPAddress and its corresponding port number. When working with, you represent a network endpoint as an IPEndPoint object. When connecting a client socket to a server socket, the client will use an IPEndPoint object to specify the network address of the server. The constructor for the Socket class has parameters that specify the address family, socket type, and protocol type that the socket uses to make connections. Before you can use a socket to communicate with remote devices, the socket must be initialized with protocol and network address information.
