這篇文章主要介紹了C#實現的UDP收發請求工具類,結合具體實例形式分析了C#針對UDP請求的監聽、接收、發送等相關操作技巧,需要的朋友可以參考下
本文實例講述了C#實現的UDP收發請求工具類別。分享給大家參考，具體如下：
初始化：
ListeningPort = int.Parse(ConfigurationManager.AppSettings["ListeningPort"]); SendingPort = int.Parse(ConfigurationManager.AppSettings["SendingPort"]); SendingIp = ConfigurationManager.AppSettings["SendingIp"];
監聽：
public static void Listen()
{
Task.Run(() =>
{
var done = false;
var listener = new UdpClient(ListeningPort);
var groupEP = new IPEndPoint(IPAddress.Any, ListeningPort);
string received_data;
byte[] receive_byte_array;
try
{
_log.Error("############Service started###########");
while (true)
{
receive_byte_array = listener.Receive(ref groupEP);
Console.WriteLine("Received a broadcast from {0}", groupEP.ToString());
received_data = Encoding.UTF8.GetString(receive_byte_array, 0, receive_byte_array.Length);
ParseCommand(received_data);
}
}
catch (Exception e)
{
_log.Error(e);
Console.WriteLine(e.ToString());
}
_log.Error("############Service stopped###########");
});
}#傳送：
public static void SendCommand(string xmlCmd)
{
try
{
var sending_socket = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp);
var sending_end_point = new IPEndPoint(IPAddress.Parse(SendingIp), SendingPort);
var send_buffer = Encoding.UTF8.GetBytes(xmlCmd);
sending_socket.SendTo(send_buffer, sending_end_point);
_log.Info("[COMMAND SENT] : " + xmlCmd);
}
catch (Exception ex)
{
_log.Error(ex);
}
}以上是關於C#如何實現的UDP收發請求工具類別的範例程式碼分析的詳細內容。更多資訊請關注PHP中文網其他相關文章！
