c# - 无法将文本从控制台输出到文本文件

Question

我正在尝试将文本写入文本文件:

        byte[] b = new byte[100];
        int k = s.Receive(b);
        Console.WriteLine("Recieved...");
        for (int i = 0; i < k; i++)
        {
            Console.Write(Convert.ToChar(b[i]));
            //TextWriter tw = new StreamWriter("output.txt");
            //tw.WriteLine(Convert.ToChar(b[i]));

        }

虽然 Console.Write 方法完美运行，并且文本输出显示在屏幕上，但是当我使用 TextWriter 方法时，应用程序会产生 100 多个错误(继续)并且不会向指定的输出文件输出任何内容

是否有任何其他方式获取“Console.Write(Convert.ToChar(b[i]))”的输出；到文本文件？

以下是错误示例:

The server is running at port 8111... The local End point is :172.16.0.37:8111 Waiting for a connection..... Connection accepted from 172.16.0.37:59307 Recieved... //Error..... at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath)

完整代码如下:

  try
    {

        IPAddress ipAd = IPAddress.Parse("172.16.0.37"); //use local m/c IP address, and use the same in the client

        /* Initializes the Listener */
        TcpListener myList = new TcpListener(ipAd, 8111);

        /* Start Listeneting at the specified port */
        myList.Start();


            Console.WriteLine("The server is running at port 8111...");
            Console.WriteLine("The local End point is  :" + myList.LocalEndpoint);
            Console.WriteLine("Waiting for a connection.....");


        Socket s = myList.AcceptSocket();
        Console.WriteLine("Connection accepted from " + s.RemoteEndPoint);

        byte[] b = new byte[100];
        int k = s.Receive(b);
        Console.WriteLine("Recieved...");
        using (var txt = File.OpenWrite("output.txt"))
        {
            for (int i = 0; i < k; i++)
            {
                Console.Write(Convert.ToChar(b[i]));
                txt.WriteLine(Convert.ToChar(b[i]));
            }
        }




        ASCIIEncoding asen = new ASCIIEncoding();
        s.Send(asen.GetBytes("The string was recieved by the server."));
        Console.WriteLine("\nSent Acknowledgement to Client");
        /* clean up */
        s.Close();
        myList.Stop();


    }
    catch (Exception e)
    {
        Console.WriteLine("Error..... " + e.StackTrace);
    }
    // Loop the process
    loop();
}

也许这就是您想要做的？

byte[] b = new byte[100];
int k = s.Receive(b);
Console.WriteLine("Recieved...");
using (var sw = new StreamWriter("output.txt"))
{
    for (int i = 0; i < k; i++)
    {
        Console.Write(Convert.ToChar(b[i]));
        sw.Write(Convert.ToChar(b[i]));
    }
}
