Socket简介
通过TCP/IP与仪器或设备通讯,在C#语言中,我们通常采用Socket。本项目是一个简单的Socket建立服务监听与Socket作为客户端请求的一个示例。
项目结构
-
客户端项目 SocketClient
主要负责作为Socket客户端发起连接请求,并发送数据
-
服务端项目 SocketDemo
主要负责作为Socket服务端,监听端口并接收连接请求,并返回应答数据
项目演示
- 先运行SocketDemo进行服务监听
Console.WriteLine("Starting:Creating Socket object");
Socket listener = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
listener.Bind(new IPEndPoint(IPAddress.Any, 2112));
listener.Listen(10);
while (true)
{
Console.WriteLine("Waiting for connection on port 2112");
Socket socket = listener.Accept();
string receivedValue = string.Empty;
while (true)
{
byte[] receivedBytes = new byte[1024];
int numBytes = socket.Receive(receivedBytes);
Console.WriteLine("Receiving.");
receivedValue += Encoding.ASCII.GetString(receivedBytes, 0, numBytes);
if (receivedValue.IndexOf("[FINAL]") > -1)
{
break;
}
}
Console.WriteLine("Received value:{0}", receivedValue);
string replyValue = "Message successfully received.";
byte[] replyMessage = Encoding.ASCII.GetBytes(replyValue);
socket.Send(replyMessage);
socket.Shutdown(SocketShutdown.Both);
socket.Close();
}
- 运行SocketClient进行模拟连接,并发送接收数据。
byte[] receivedBytes = new byte[1024];
IPHostEntry ipHost = Dns.Resolve("127.0.0.1");
IPAddress ipAddress = ipHost.AddressList[0];
IPEndPoint ipEndPoint = new IPEndPoint(ipAddress, 2112);
Console.WriteLine("Starting:Creating Socket object");
Socket sender = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
sender.Connect(ipEndPoint);
Console.WriteLine("Successfully connected to {0}", sender.RemoteEndPoint);
string sendingMessage = "Hello World Socket Test";
Console.WriteLine("Creating Message;Hello World Socket Test");
byte[] forwardMessage = Encoding.ASCII.GetBytes(sendingMessage + "[FINAL]");
sender.Send(forwardMessage);
int totalBytesReceived = sender.Receive(receivedBytes);
Console.WriteLine("Message provided from server: {0}", Encoding.ASCII.GetString(receivedBytes, 0, totalBytesReceived));
sender.Shutdown(SocketShutdown.Both);
sender.Close();
Thread.Sleep(1000);
Console.ReadLine();
后记
H5支持WebSocket,预计将来在通讯领域应用会更加广泛,示例程序见博客:[C# WebSocket模拟发送接收](http://www.cnblogs.com/bmbh/p/5174884.html)
