我正在尝试在.NETMF 4.3中为我的FEZ Spider工具包编写一个TCP服务器。
public partial class Program
{
void ProgramStarted()
{
ethernetJ11D.NetworkInterface.Open();
ethernetJ11D.UseStaticIP("192.168.0.8", "255.255.255.0", "192.168.0.1");
Socket serverSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
EndPoint endPoint = new IPEndPoint(IPAddress.Any, 7777);
serverSocket.Bind(endPoint);
serverSocket.Listen(10);
new Thread(() =>
{
while (true)
{
Debug.Print("Network up: " + ethernetJ11D.IsNetworkUp);//true
Debug.Print("Network connected: " + ethernetJ11D.IsNetworkConnected);//true
System.Net.Sockets.Socket clientSocket = serverSocket.Accept();//exception!
new Thread(new Request(clientSocket).Process);
}
}).Start();
}
serverSocket.Accept方法抛出一个错误代码为10050的SocketException。This页面说它是WSAENETDOWN:网络已关闭。但是,ethernetJ11D的属性表明连接已启动,我可以毫无问题地ping设备。我做错了什么?
修改
当我尝试运行以下客户端时,我在socket.Connect调用上得到了相同的异常。
ethernetJ11D.NetworkInterface.Open();
ethernetJ11D.UseStaticIP("192.168.0.8", "255.255.255.0", "192.168.0.1");
Socket socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
IPEndPoint endpoint = new IPEndPoint(IPAddress.Parse("192.168.0.5"), 7777);
socket.Connect(endpoint);
Debug.Print("connected");
byte[] msg = new byte[] { 7, 77, 222 };
socket.Send(msg);
编辑2
我试图改为实现UDP客户端。它也不起作用。
答案 0 :(得分:2)
我已经解决了这个问题:
IPAddress.Any
更改为静态IP,例如。 IPAddress.Parse("192.168.0.8")
。Thread.Sleep(3000)
。看来界面的网络设置配置需要一些时间。
