Sockets Raspberry pi 2服务器没有响应

我用运行Windows10IoT的raspberry pi 2启动了一个客户机-服务器项目，这非常好，因为您可以在PC和RPI2上运行相同的应用程序。考虑到这一点，我只创建了一个既可以充当客户端又可以充当服务器的应用程序，然后将其部署在两个设备上，并将其中一个用作服务器，另一个用作客户端。唯一的问题是服务器端从不应答客户机连接调用

我的代码如下：

服务器：

///servername is the port that I use
///hostadapter is an adapter helper obj that has a HostName property set to my Ip address.
public async void Start(string serverName, HostName hostAdapter)
    {
        //create the "server" object
        serverListener = new StreamSocketListener();
        serverListener.ConnectionReceived += ServerListener_ConnectionReceived;

        try
        {
            await serverListener.BindEndpointAsync(hostAdapter, serverName);
            Started = true;
        }
        catch (Exception ee)
        {
            Started = false;
            myConsole.Print("error while starting server: " + ee.Message);
        }
    }

private async void ServerListener_ConnectionReceived(StreamSocketListener sender, StreamSocketListenerConnectionReceivedEventArgs args)
    {

        myConsole.Print("connection recieved callback called");
        DataReader reader = new DataReader(args.Socket.InputStream);
        DataWriter ServerWriter = new DataWriter(args.Socket.OutputStream);
        string ServerAnswer = "message recieved by server";

        try
        {
            while (true)
            {
                // Read first 4 bytes (length of the subsequent string).
                uint sizeFieldCount = await reader.LoadAsync(sizeof(uint));
                if (sizeFieldCount != sizeof(uint))
                {
                    // The underlying socket was closed before we were able to read the whole data.
                    return;
                }

                // Read the string.
                uint stringLength = reader.ReadUInt32();
                uint actualStringLength = await reader.LoadAsync(stringLength);
                if (stringLength != actualStringLength)
                {
                    // The underlying socket was closed before we were able to read the whole data.
                    return;
                }

                ServerWriter.WriteUInt32(ServerWriter.MeasureString(ServerAnswer));
                ServerWriter.WriteString(ServerAnswer);
                await ServerWriter.StoreAsync();
            }
        }
        catch (Exception exception)
        {
            myConsole.Print(exception.Message);
        }
    }

客户：

public async void Connect(string serverIP, string serverPort)
    {

        try
        {
            ServerHost = new HostName(serverIP);
        }
        catch (Exception ee)
        {
            return;
        }

        try
        {
            //open socket
            ClientSocket = new StreamSocket();
            await ClientSocket.ConnectAsync(ServerHost, serverPort);
            Connected = true;
        }
        catch (Exception ex)
        {
            ClientSocket.Dispose();
            ClientSocket = null;

            myConsole.Print(ex.Message);

            Connected = false;
        }
    }

非常感谢您的帮助。我已经下载了wireshark，以便能够监视网络数据，并且找到了客户端发送的tcp[syn]包，但我看不到任何tcp[syn ack]包。

结果是我缺少了一项功能。通过以太网进行通信所需的功能包括

<Capabilities>
    <Capability Name="internetClient" />
    <Capability Name="privateNetworkClientServer" />
    <Capability Name="internetClientServer" />
</Capabilities>

我只添加了privateNetworkClientServer和internetClient..

您可以尝试

BindServiceNameAsync（）

而不是

BindEndpointAsync

？我已经尝试了这两种方法。我真的不明白其中的区别。我使用BindEndpointAsync（）运行，因为我在microsoft示例中看到了它。因此，如果我理解正确，服务器可以在PC上运行，但不能在raspberry上运行，或者服务器永远不能工作？如果客户机和服务器都在同一台PC上，服务器就可以工作。一旦它们在不同的机器上运行，它们就不能工作。i、 e PC客户端和服务器工作正常。PC客户端，rPI服务器不工作。PC服务器和rPI客户端不工作。是否启用了本地网络功能？
