关于UDP的 求助！！！
服务器端的代码如下：
public class Class1
{
static void Main(string[] args)
{
Custom.StartListener();
}
}
public class Custom
{
private static readonly IPAddress GroupAddress = IPAddress.Parse("127.0.0.1");
private const int GroupPort = 11000;
public static void StartListener()
{
//bool done = false;
UdpClient listener = new UdpClient();
IPEndPoint groupEP = new IPEndPoint(GroupAddress, GroupPort);
try
{
//listener.JoinMulticastGroup(GroupAddress);
listener.Connect("127.0.0.1",11000);
while (true)
{
Console.WriteLine("Waiting for broadcast");
byte[] bytes = listener.Receive(ref groupEP);
Console.WriteLine("Received broadcast from {0} :\n {1}\n",
groupEP.Address.ToString(),
Encoding.ASCII.GetString(bytes, 0, bytes.Length));
}
}
catch (Exception e)
{
Console.WriteLine(e.ToString());
}
}
}
客户端的代码：
public class Client
{
static void Main(string[] args)
{
Console.WriteLine("输入数据");
Send(Console.ReadLine());
Console.ReadLine();
}
private static IPAddress GroupAddress = IPAddress.Parse("127.0.0.1");
private static int GroupPort = 11000;
private static void Send(string message)
{
UdpClient sender = new UdpClient();
IPEndPoint groupEP = new IPEndPoint(GroupAddress, GroupPort);
try
{
Console.WriteLine("Sending datagram : {0}", message);
byte[] bytes = Encoding.ASCII.GetBytes(message);
sender.Send(bytes, bytes.Length, "192.168.0.16", 4567);
sender.Close();
}
catch (Exception e)
{
Console.WriteLine(e.ToString());
}
}
}
现在有问题了，我服务器接收不到数据。。求大侠指教啊。。小弟先行感谢了，！

客户端不要指定端口，而且你这服务端和客户端端口都一样，肯定不行的
[解决办法]
Connect 是发送用的
- C# code
// 服务端方法public static void StartListener(){ UdpClient listener = new UdpClient(GroupPort); IPEndPoint groupEP = new IPEndPoint(GroupAddress, GroupPort); try { while (true) { Console.WriteLine("Waiting for broadcast"); byte[] bytes = listener.Receive(ref groupEP); Console.WriteLine("Received broadcast from {0} :\n {1}\n", groupEP.Address.ToString(), Encoding.ASCII.GetString(bytes, 0, bytes.Length)); } } catch (Exception e) { Console.WriteLine(e.ToString()); }}// 客户端方法private static void Send(string message){ UdpClient sender = new UdpClient(); IPEndPoint groupEP = new IPEndPoint(GroupAddress, GroupPort); try { Console.WriteLine("Sending datagram : {0}", message); byte[] bytes = Encoding.ASCII.GetBytes(message); sender.Send(bytes, bytes.Length, groupEP); sender.Close(); } catch (Exception e) { Console.WriteLine(e.ToString()); }}
