＆＃34;通常只允许使用每个套接字地址（协议/网络地址/端口）＆＃34;

Question

我正在尝试使用简单的客户端和给我的服务器进行网络编程。当我的客户端连接到服务器时，服务器打印消息“通常只允许使用每个套接字地址（协议/网络地址/端口）”

我使用的端口是6000，localhost是主机。

我正在使用Tcp客户端。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Net.Sockets;

namespace ConsoleTankClientVersion1
{
    class Program
    {

        static void Main(string[] args)
        {
            TcpClient client = null;
            NetworkStream netStream = null;

            //server ip
            String server = "127.0.0.1";

            //server port
            int servPort = 6000;

            //The input string is converted to a stream of bytes
            byte[] byteBuffer = Encoding.ASCII.GetBytes("JOIN#");


            try
            {

                    // Create socket that is connected to server on port 6000
                    client = new TcpClient(server, servPort);

                    Console.WriteLine("Connected to server... sending join string");

                    netStream = client.GetStream();



                // Send the encoded string to the server
                netStream.Write(byteBuffer, 0, byteBuffer.Length);

                Console.WriteLine("Sent {0} bytes to server...", byteBuffer.Length);

                int totalBytesRcvd = 0; // Total bytes received so far
                int bytesRcvd = 0; // Bytes received in last read

                // Receive the same string back from the server
                while (totalBytesRcvd < byteBuffer.Length)
                {
                    if ((bytesRcvd = netStream.Read(byteBuffer, totalBytesRcvd,
                    byteBuffer.Length - totalBytesRcvd)) == 0)
                    {
                        Console.WriteLine("Connection closed prematurely.");
                        break;
                    }
                    totalBytesRcvd += bytesRcvd;
                }
                Console.WriteLine("Received {0} bytes from server: {1}", totalBytesRcvd,
                Encoding.ASCII.GetString(byteBuffer, 0, totalBytesRcvd));

            }
            catch (Exception e)
            {
                Console.WriteLine(e.Message);
            }




        }
    }
}

TcpTimedWaitDelay是30秒 最大用户端口值为60000
