通过本文主要向大家介绍了c#udp通信实例,c#udp通信,c#udp异步通信,c#udp高并发异步通信,c#udp等相关知识,希望对您有所帮助,也希望大家支持linkedu.com www.linkedu.com
    网络通信协议中的UDP通信是无连接通信,客户端在发送数据前无需与服务器端建立连接,即使服务器端不在线也可以发送,但是不能保证服务器端可以收到数据。本文实例即为基于C#实现的UDP通信。具体功能代码如下:
服务器端代码如下:
static void Main(string[] args) 
{ 
  UdpClient client = null; 
  string receiveString = null; 
  byte[] receiveData = null; 
  //实例化一个远程端点,IP和端口可以随意指定,等调用client.Receive(ref remotePoint)时会将该端点改成真正发送端端点 
  IPEndPoint remotePoint = new IPEndPoint(IPAddress.Any, 0); 
  while (true) 
  { 
 client = new UdpClient(11000); 
 receiveData = client.Receive(ref remotePoint);//接收数据 
 receiveString = Encoding.Default.GetString(receiveData); 
 Console.WriteLine(receiveString); 
 client.Close();//关闭连接 
  } 
}
</div>
客户端代码如下:
static void Main(string[] args) 
{ 
  string sendString = null;//要发送的字符串 
  byte[] sendData = null;//要发送的字节数组 
  UdpClient client = null; 
  IPAddress remoteIP = IPAddress.Parse("127.0.0.1"); 
  int remotePort = 11000; 
  IPEndPoint remotePoint = new IPEndPoint(remoteIP, remotePort);//实例化一个远程端点 
  while (true) 
  { 
 sendString = Console.ReadLine(); 
 sendData = Encoding.Default.GetBytes(sendString); 
 client = new UdpClient(); 
 client.Send(sendData, sendData.Length, remotePoint);//将数据发送到远程端点 
 client.Close();//关闭连接 
  } 
}
</div>
程序最终运行效果如下:
