我正在使用UDP服务器，可以很好地接收数据，但是我不知道如何存储端点以将数据发送回去。
SetupServer()我不知道该如何获得评论的终极评论EndPoint。
这是我的服务器代码：
static private byte[] buffer = new byte[1024];
static private Socket serverSocket = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp);
private const int port = 904;
static void Main(string[] args) {
SetupServer();
Console.ReadLine();
}
static private void SetupServer() {
Console.WriteLine($"{DateTime.Now}: Setting up server on {port}...");
EndPoint remoteEP = new IPEndPoint(IPAddress.Any, port);
serverSocket.Bind(remoteEP);
Console.WriteLine($"{DateTime.Now}: Server created successfully");
serverSocket.BeginReceiveFrom(buffer, 0, buffer.Length, SocketFlags.None, ref remoteEP,BeginReceive, null);
//serverSocket.SendTo(buffer, 0, buffer.Length, SocketFlags.None, remoteEP);
}
static private void BeginReceive(IAsyncResult ar) {
int recv = serverSocket.EndReceive(ar);
byte[] dataBuf = new byte[recv];
Array.Copy(buffer, dataBuf, recv);
Console.WriteLine($"{DateTime.Now}: {Encoding.ASCII.GetString(dataBuf)}");
EndPoint remoteEP = new IPEndPoint(IPAddress.Any, port);
serverSocket.BeginReceiveFrom(buffer, 0, buffer.Length, SocketFlags.None, ref remoteEP, BeginReceive, null);
}
我知道该怎么做。我serverSocket.EndReceive(ar)将BeginReceive方法中的替换为，EndReceiveFrom(ar,ref epSender)并使用该端点（epSender）可以调用该BeginReceiveFrom方法。
static private void SetupServer() {
Console.WriteLine($"{DateTime.Now}: Setting up server on {port}...");
EndPoint remoteEP = new IPEndPoint(IPAddress.Any, port);
serverSocket.Bind(remoteEP);
Console.WriteLine($"{DateTime.Now}: Server created successfully");
serverSocket.BeginReceiveFrom(buffer, 0, buffer.Length, SocketFlags.None, ref remoteEP,BeginReceive, serverSocket);
}
static private void BeginReceive(IAsyncResult ar) {
EndPoint epSender = new IPEndPoint(IPAddress.Any, port);
int recv = serverSocket.EndReceiveFrom(ar,epSender);
byte[] dataBuf = new byte[recv];
Array.Copy(buffer, dataBuf, recv);
Console.WriteLine($"{DateTime.Now}: {Encoding.ASCII.GetString(dataBuf)}");
serverSocket.SendTo(dataBuf,epSender)
serverSocket.BeginReceiveFrom(buffer, 0, buffer.Length, SocketFlags.None, ref remoteEP, BeginReceive, serverSocket);
}
