C# UDPClient仅接收一个数据报

我正在尝试读取连续的UDP字节（或者一次至少读取1个以上）。我的缓冲区是单个数据报/数据包大小的4倍（1000字节）

一次只读取一个数据报数据包。如果你想读取多个数据报，你需要多次调用<代码>接收< /代码>。

如果你想接收多个数据包，你应该考虑使用异步方法来接收它们。UdpClient类有一个异步习惯用法，您可以给它一个回调函数，然后继续执行其他处理（例如更新UI）

你要发送多少数据？你们寄的速度是多少？

 Byte[] receiveBytes = new Byte[4096];

 UdpClient udpClient = new UdpClient(56885);
 IPEndPoint RemoteIpEndPoint = new IPEndPoint(IPAddress.Any, 0);
 Byte[] receiveBytes = udpClient.Receive(ref RemoteIpEndPoint);

public static bool messageReceived = false;

public static void ReceiveCallback(IAsyncResult ar)
{
  UdpClient u = (UdpClient)((UdpState)(ar.AsyncState)).u;
  IPEndPoint e = (IPEndPoint)((UdpState)(ar.AsyncState)).e;

  Byte[] receiveBytes = u.EndReceive(ar, ref e);
  string receiveString = Encoding.ASCII.GetString(receiveBytes);

  Console.WriteLine("Received: {0}", receiveString);
  messageReceived = true;
}

public static void ReceiveMessages()
{
  // Receive a message and write it to the console.
  IPEndPoint e = new IPEndPoint(IPAddress.Any, listenPort);
  UdpClient u = new UdpClient(e);

  UdpState s = new UdpState();
  s.e = e;
  s.u = u;

  Console.WriteLine("listening for messages");
  u.BeginReceive(new AsyncCallback(ReceiveCallback), s);

  // Do some work while we wait for a message. For this example, 
  // we'll just sleep 
  while (!messageReceived)
  {
    Thread.Sleep(100);
  }
}
