我在MSND中使用此服务器示例:http://msdn.microsoft.com/en-us/library/fx6588te.aspx
由于某些原因,我的服务器拒绝在此_listener.Bind(localEndPoint);
的此功能上进行连接,但错误为Only one usage of each socket address (protocol/network address/port) is normally permitted
直到几分钟前,我没有遇到问题,Sarver连接没有问题,突然发生了
public static void StartListening(IPAddress ipAddress, int port)
{
_isServerRunning = true;
// Data buffer for incoming data.
byte[] bytes = new Byte[1024];
// Establish the local endpoint for the socket.
// The DNS name of the computer
// running the listener is "host.contoso.com".
//IPHostEntry ipHostInfo = Dns.Resolve(Dns.GetHostName());
//IPAddress ipAddress = IPAddress.Parse("192.168.0.100"); //ipHostInfo.AddressList[0];
IPEndPoint localEndPoint = new IPEndPoint(ipAddress, port);
// Create a TCP/IP socket.
_listener = new Socket(AddressFamily.InterNetwork,
SocketType.Stream, ProtocolType.Tcp);
// Bind the socket to the local endpoint and listen for incoming connections.
try
{
_listener.Bind(localEndPoint);
_listener.Listen(100);
while (true)
{
// Set the event to nonsignaled state.
allDone.Reset();
// Start an asynchronous socket to listen for connections.
Console.WriteLine("Waiting for a connection...");
_listener.BeginAccept(
new AsyncCallback(AcceptCallback),
_listener);
// Wait until a connection is made before continuing.
allDone.WaitOne();
}
}
catch (Exception e)
{
Console.WriteLine(e.ToString());
}
//Console.WriteLine("\nPress ENTER to continue...");
Console.Read();
}
这个错误意味着什么?

这很可能意味着本地端口仍然保留。这可能是空闲的,因为另一个进程仍在运行并保持sockewt打开,或者因为dSO_LINGER套接字选项定义的超时时间没有超时。我不熟悉c#,但应该有办法设置elinger超时。
您可以使用netstat命令告诉套接字的当前状态。
