C# UdpClient 接收有效，ReceiveAsync 挂起

问题描述

我目前正在尝试重构一些旧代码，并达到了尝试异步进行 UDP 通信的程度。我的旧代码接收数据包：

ClientListener = new UdpClient(ClientListenPort);
ServerEp = new IPEndPoint(IPAddress.Any,ClientListenPort);
try
{
    while (!stop)
    {
         byte[] ReceivedData = ClientListener.Receive(ref ServerEp);
         LastReceivedTimeMS = Environment.TickCount;
         if (!FoundServer)
         {
             ServerIP = ServerEp.Address.ToString();
             FoundServer = true;
         }
         HandleReceiveData(ReceivedData);
     }
}
 catch (Exception e)
{
    Debug.Log("Error: " + e);
}

而异步方式不接收任何东西（挂起）。有人知道我做错了什么吗？

ClientListener = new UdpClient(ClientListenPort);
ServerEp = new IPEndPoint(IPAddress.Any,ClientListenPort);
try
{
    Task.Run(async () =>
    {
        while (!stop)
        {
            UdpReceiveResult receivedResults = await ClientListener.ReceiveAsync();
            if (!FoundServer)
            {
                ServerIP = receivedResults.RemoteEndPoint.Address.ToString();
                ServerEp = receivedResults.RemoteEndPoint;
                FoundServer = true;
            }
            HandleReceiveData(receivedResults.Buffer);
        }
    });
}
catch (Exception e)
{
    Debug.Log("Error: " + e);
}
