Question

为什么我无法向服务器发送消息，有人可以帮助我吗？编程语言是 C#，我已经关闭了我的防火墙，但它仍然无法工作。

这是我的服务器

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using SimpleTCP;

namespace TCP
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        SimpleTcpServer server;

        private void Form1_Load(object sender, EventArgs e)
        {
            server = new SimpleTcpServer();
            server.Delimiter = 0x13;
            server.StringEncoder = Encoding.UTF8;
            server.DataReceived += Server_DataReceived;
        }

        private void Server_DataReceived(object sender, SimpleTCP.Message e)
        {
            txtStatus.Invoke((MethodInvoker)delegate ()
            {
                txtStatus.Text += e.MessageString;
                e.ReplyLine(string.Format("You said: {0}", e.MessageString));
            });
        }

        private void btnStart_Click(object sender, EventArgs e)
        {
            txtStatus.Text += "Server starting...";
            System.Net.IPAddress ip = System.Net.IPAddress.Parse(txtHost.Text);
            server = new SimpleTcpServer().Start(ip, Convert.ToInt32(txtPort.Text));
            txtStatus.Text += Environment.NewLine + "Server connected!";
            //server.Start(ip, Convert.ToInt32(txtPort.Text));
        }

        private void btnStop_Click(object sender, EventArgs e)
        {
            if (server.IsStarted)
                server.Stop();
        }      
    }
}

这是我的客户

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using SimpleTCP;

namespace Client
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }
 
        SimpleTcpClient client;
 
        private void btnConnect_Click(object sender, EventArgs e)
        {
            btnConnect.Enabled = false;
            //Connect to server
            client.Connect(txtHost.Text, Convert.ToInt32(txtPort.Text));
        }
 
        private void Form1_Load(object sender, EventArgs e)
        {
            client = new SimpleTcpClient();
            client.StringEncoder = Encoding.UTF8;
            client.DataReceived += Client_DataReceived;
        }
 
        private void Client_DataReceived(object sender, SimpleTCP.Message e)
        {
            //Update message to txtStatus
            txtStatus.Invoke((MethodInvoker)delegate ()
            {
                txtStatus.Text += e.MessageString;               
            });
        }
 
        private void btnSend_Click(object sender, EventArgs e)
        {
            client.WriteLineAndGetReply(txtMessage.Text, TimeSpan.FromSeconds(0));
        }
    }
}

不知道是连接问题还是消息问题

C# TCP 连接，客户端无法向服务器发送消息
