C#中應用UDP通訊實例

C#中應用UDP通訊實例。本站提示廣大學習愛好者：（C#中應用UDP通訊實例）文章只能為提供參考，不一定能成為您想要的結果。以下是C#中應用UDP通訊實例正文

收集通訊協定中的UDP通訊是無銜接通訊，客戶端在發送數據前無需與辦事器端樹立銜接，即便辦事器端不在線也能夠發送，然則不克不及包管辦事器端可以收到數據。本文實例即為基於C#完成的UDP通訊。詳細功效代碼以下：

辦事器端代碼以下：

static void Main(string[] args) 
{ 
  UdpClient client = null; 
  string receiveString = null; 
  byte[] receiveData = null; 
  //實例化一個長途端點，IP和端口可以隨便指定，等挪用client.Receive(ref remotePoint)時會將該端點改成真正發送端端點 
  IPEndPoint remotePoint = new IPEndPoint(IPAddress.Any, 0); 

  while (true) 
  { 
 client = new UdpClient(11000); 
 receiveData = client.Receive(ref remotePoint);//吸收數據 
 receiveString = Encoding.Default.GetString(receiveData); 
 Console.WriteLine(receiveString); 
 client.Close();//封閉銜接 
  } 
}

客戶端代碼以下：

static void Main(string[] args) 
{ 
  string sendString = null;//要發送的字符串 
  byte[] sendData = null;//要發送的字節數組 
  UdpClient client = null; 

  IPAddress remoteIP = IPAddress.Parse("127.0.0.1"); 
  int remotePort = 11000; 
  IPEndPoint remotePoint = new IPEndPoint(remoteIP, remotePort);//實例化一個長途端點 

  while (true) 
  { 
 sendString = Console.ReadLine(); 
 sendData = Encoding.Default.GetBytes(sendString); 

 client = new UdpClient(); 
 client.Send(sendData, sendData.Length, remotePoint);//將數據發送到長途端點 
 client.Close();//封閉銜接 
  } 
}
