这篇文章主要介绍了c#实现的udp收发请求工具类,结合具体实例形式分析了c#针对udp请求的监听、接收、发送等相关操作技巧,需要的朋友可以参考下
本文实例讲述了c#实现的udp收发请求工具类。分享给大家供大家参考，具体如下：
初始化：
listeningport = int.parse(configurationmanager.appsettings["listeningport"]);
sendingport = int.parse(configurationmanager.appsettings["sendingport"]);
sendingip = configurationmanager.appsettings["sendingip"];
监听：
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###########");
});
}
发送：
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);
}
}
以上就是关于c#如何实现的udp收发请求工具类的示例代码分析的详细内容。
