Question

基本上我已经编写了这个程序来检查字符串。我已经使用套接字方法了。

问题是，我无法弄清楚如何以及在何处准确地打开此程序中的文件并搜索字符串。我希望客户端能够键入/搜索他们想要的任何字符串，而不是在程序中提供搜索字符串。当我运行程序时，我需要客户端屏幕上的输出。

如何改进此计划？有人可以帮我解决一下代码吗？

这是我的计划：

class Program
{
    static void Main(string[] args)
    {
        TcpListener serversocket = new TcpListener(8888);
        TcpClient clientsocket = default(TcpClient);
        serversocket.Start();
        Console.WriteLine(">> Server Started");
        while (true)
        {
            clientsocket = serversocket.AcceptTcpClient();
            Console.WriteLine("Accept Connection From Client");
            LineMatcher lm = new LineMatcher(clientsocket);
            Thread thread = new Thread(new ThreadStart(lm.Run));
            thread.Start();
            Console.WriteLine("Client connected");
        }
        Console.WriteLine(" >> exit");
        Console.ReadLine();
        clientsocket.Close();
        serversocket.Stop();
    }
}
public class LineMatcher
{
    private static Regex _regex = new Regex("not|http|console|application", RegexOptions.Compiled | RegexOptions.IgnoreCase | RegexOptions.CultureInvariant);
    private TcpClient _client;
    public LineMatcher(TcpClient client)
    {
        _client = client;
    }

    public void Run()
    {
        try
        {
            using (var reader = new StreamReader(_client.GetStream()))
            {
                string line;
                int lineNumber = 0;
                while (null != (line = reader.ReadLine()))
                {
                    lineNumber += 1;
                    foreach (Match match in _regex.Matches(line))
                    {

                        Console.WriteLine("Line {0} matches {1}", lineNumber, match.Value);
                    }
                }

            }
        }
        catch (Exception ex)
        {
            Console.Error.WriteLine(ex.ToString());
        }
        Console.WriteLine("Closing client");
        _client.Close();
    }
}

这是一个适合我的简单演示客户端：

using System;
using System.IO;
using System.Net.Sockets;
using System.Text;

namespace AClient
{
    class Client
    {
        static void Main()
        {
            using (var client = new TcpClient("localhost", 8888))
            {
                Console.WriteLine(">> Client Started");

                using (var r = new StreamReader(@"E:\input.txt", Encoding.UTF8))
                using (var w = new StreamWriter(client.GetStream(), Encoding.UTF8))
                {
                    string line;
                    while (null != (line = r.ReadLine()))
                    {
                        w.WriteLine(line);
                        w.Flush(); // probably not necessary, but I'm too lazy to find the docs
                    }
                }

                Console.WriteLine(">> Goodbye");
            }
        }
    }
}

套接字接受多个客户端，但我无法打开该文件
