UdpClient udpClient=newUdpClient(RemoteIpEndPoint);//如果这里写while(true) 则会不停挂起异步接收操作,直到占满缓冲区间或队列。会报“由于系统缓冲区空间不足或队列已满,不能执行套接字上的操作”的错UdpState s =newUdpState(udpClient, RemoteIpEndPoint); udpClient.BeginReceive(EndReceive, s); }privatest...
使用UdpClient的BeginReceive和EndReceive方法替代Receive方法,以便在异步方式下正确获取发送方客户端的端口号。具体代码示例如下: private void ReceiveCallback(IAsyncResult ar) { UdpClient udpClient = (UdpClient)ar.AsyncState; IPEndPoint ipEndPoint = new IPEndPoint(IPAddress.Any, 0); byte[] receiveBytes = ...
UdpClient u=((UdpState)(ar.AsyncState)).u; IPEndPoint e=((UdpState)(ar.AsyncState)).e;byte[] receiveBytes = u.EndReceive(ar,refe);stringreceiveString =Encoding.ASCII.GetString(receiveBytes); Console.WriteLine($"Received: {receiveString}"); messageReceived=true; }publicstaticvoidReceiveMessage...
byte[] receiveBytes = u.EndReceive(ar, ref e); string receiveString = Encoding.ASCII.GetString(receiveBytes); Console.WriteLine($"Received: {receiveString}"); messageReceived = true; } public static void ReceiveMessages() { // Receive a message and write it to the console. ...
在ReceiveCallback回调函数中,我们通过调用UdpClient.EndReceive方法获取接收到的数据,并进行相应的处理。然后再次调用StartReceive方法,实现循环接收数据的功能。 这种方式适用于需要持续接收UDP数据包的场景,比如实时数据传输、网络游戏等。在实际应用中,可以根据具体需求对接收到的数据进行解析和处理。
byte[] data = client.EndReceive(ar, ref ep);Console.WriteLine("收到数据");//收到数据 client.Close();} } //Receive public void Main(){ using (UdpClient client = new UdpClient(8080)){ IPEndPoint ep = new IPEndPoint(IPAddress.Any, 0);byte[] data = client.Receive(ref ep...
(IAsyncResult ar) { IPEndPoint remoteEP = null; byte[] receivedBytes = udpClient.EndReceive(ar, ref remoteEP); string receivedData = Encoding.UTF8.GetString(receivedBytes); Console.WriteLine($"Received: {receivedData}"); // 继续异步接收 udpClient.BeginReceive(ReceiveCallback, null); } // ...
(IPEndPoint)result.RemoteEndPoint; byte[] receivedData = udpClient.EndReceive(result, ref remoteEndPoint); string receivedMessage = Encoding.ASCII.GetString(receivedData); Console.WriteLine($"Received: {receivedMessage} from {remoteEndPoint}"); // 异步发送响应 string responseMessage = "Hello from ...
我的接收是通过异步BeginReceive投递的,而发送则是以阻塞方式Send 其中EndReceive也进行了线程同步, UDP的接收缓冲区我也设置得足够大了,TCP连接限制和端口可用数我也修改过,但问题依然无法解决。 让这个问题搞了几天了,希望大家能提供些思路和解决办法 ,真的古怪...
