Question

我不太确定代码会发生什么。我有一个程序可以读入输入（来自本地主机上的telnet客户端）并将其存储到字典中。此输入按需存储;

PersonsName＆＃34;位于＆＃34;

然而，当没有＆＃34;围绕输入的第二部分;

PersonName位于位置

我收到此错误; System.IO.IOException：无法从传输连接读取数据：远程主机强制关闭现有连接。 ---＆GT; System.Net.Sockets.SocketException：远程主机强制关闭现有连接在System.Net.Sockets.Socket.Receive（Byte []缓冲区，Int32偏移量，Int32大小，SocketFlags socketFlags）在System.Net.Sockets.NetworkStream.Read（Byte []缓冲区，Int32偏移量，Int32大小） ---内部异常堆栈跟踪结束--- 在System.Net.Sockets.NetworkStream.Read（Byte []缓冲区，Int32偏移量，Int32大小）在System.IO.StreamReader.ReadBuffer（）在System.IO.StreamReader.ReadLine（）位于C：\ Users \ UserPC \ source \ repos \ locationserver \ locationserver \ Program.cs中的locationserver.Program.doRequest（NetworkStream socketStream）：第61行

我的代码如下

 public static Dictionary<string, string> dataBase;

    static void Main(string[] args)
    {
        //create a database then populate it with an item so its not null
        dataBase = new Dictionary<string, string>();
        dataBase.Add("Person", "in Location");
        runServer();
    }

    static void runServer()
    {
        TcpListener listener;
        Socket connection;
        NetworkStream socketStream;
        try
        {
            listener = new TcpListener(IPAddress.Any, 43);
            listener.Start();
            Console.WriteLine("Server has now started");
            while (true)
            {
                connection = listener.AcceptSocket();
                socketStream = new NetworkStream(connection);
                Console.WriteLine("A connection has been made");
                doRequest(socketStream);
                socketStream.Close();
                connection.Close();
            }
        }
        catch (Exception e)
        {
            Console.WriteLine(e.ToString());
        }
    }

    static void doRequest(NetworkStream socketStream)
    {
        try
        {
            //set timeout value to 1 second
            socketStream.ReadTimeout = 1000;
            socketStream.WriteTimeout = 1000;

            StreamWriter sw = new StreamWriter(socketStream);
            StreamReader sr = new StreamReader(socketStream);

            string line = sr.ReadLine().Trim();
            //A load of code it never goes into
}
catch (Exception e)
        {
            Console.WriteLine(e);
        }

    }

}

已经过了一段时间并且不知道发生了什么。任何帮助都会很棒。谢谢

编辑：发生错误的行如下

string line = sr.ReadLine().Trim();

＆＃34;＆＃34;无法从传输连接中读取数据。已添加
