C#基于TCP/IP实现接收并推送数据的小工具
作者：对号东
这篇文章主要为大家详细介绍了C#如何基于TCP/IP实现接收并推送数据的小工具,文中的示例代码讲解详细,感兴趣的小伙伴可以了解下
一、前言：基于.NET C#的「数据打通」小帮手
做物联网设备联调、服务端数据采集时，是不是总遇到这些需求：
- 用 C# 快速搭建 TCP服务器端、客户端，和设备 / 服务器建立稳定连接
- 实时接收 TCP 数据流，自动推送到业务 API 接口
- 断连自动重试、推送失败重发，还得有清晰日志方便排查
作为.NET 开发者，之前用 Python 写过类似工具，但项目需要 C# 版本，索性重新造个轮子～ 这个工具轻量无依赖，兼顾「连接稳定性测试」和「数据自动转发」，今天把完整思路 + 代码拆解分享，新手也能直接复用！
当然如果您是需要找一个现成的工具放在windows10/11下直接使用，也可以略过源码研究，直接拿走发行版本使用即可。
功能预览：
二、核心功能 & 技术栈
先明确工具定位，避免功能冗余：
- TCP 客户端：支持配置 IP / 端口，断连自动重试（无需手动重启）
- 数据接收：实时监听 TCP 流，处理粘包 / 半包（自定义解析规则）
- API 推送：异步推送数据到目标接口，支持超时设置、失败重试
- 日志记录：记录连接状态、数据收发、API 推送结果（基于.NET 自带日志）
技术栈（纯.NET 原生，无需第三方依赖）：
开发语言：C# （兼容.NET Core 3.1/.>NET4+/NET 5+/.NET 6+）
核心类库：
- System.Net.Sockets（TCP 连接与数据收发）
- System.Net.HttpWebRequest（API 请求）
三、核心代码拆解（带详细注释）
下面分模块讲解，完整代码可直接拉到文末获取，复制就能运行～
1. 核心服务器端工具类-TcpServerTool
负责执行TCP数据接收，并调用API接口地址将收到的数据进行推送。持续接收数据，处理断连重试和粘包问题。

}5. 主窗口模块-MainForm
功能聚合主窗口界面：
using System;
using System.IO;
using System.Windows.Forms;
namespace JoTcp
{
public partial class MainForm : Form
{
Frm_TcpClient tcpClient;
Frm_TcpServer tcpServer;
public MainForm()
{
InitializeComponent();
this.MinimumSize = new System.Drawing.Size(820, 745);
this.Size = new System.Drawing.Size(820, 745);
//1197, 189
}
/// <summary>
/// 点击服务端按钮，显示服务端
/// </summary>
private void btn_TCPServer_Click(object sender, EventArgs e)
{
if (tcpServer == null)
{
tcpServer = new Frm_TcpServer();
}
panel_Container.Controls.Clear();//移除所有控件
tcpServer.TopLevel = false;
tcpServer.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;
panel_Container.Width = tcpServer.Width;
tcpServer.Dock = DockStyle.Fill;
panel_Container.Controls.Add(tcpServer);
tcpServer.Show();
}
/// <summary>
/// 点击客户端按钮，显示客户端
/// </summary>
private void btn_TCPClient_Click(object sender, EventArgs e)
{
if (tcpClient == null)
{
tcpClient = new Frm_TcpClient();
}
panel_Container.Controls.Clear();//移除所有控件
tcpClient.TopLevel = false;
tcpClient.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;
panel_Container.Width = tcpClient.Width;
tcpClient.Dock = DockStyle.Fill;
panel_Container.Controls.Add(tcpClient);
tcpClient.Show();
}
/// <summary>
/// 窗体加载时，显示服务端
/// </summary>
private void MainForm_Load(object sender, EventArgs e)
{
if (tcpServer == null)
{
tcpServer = new Frm_TcpServer();
}
panel_Container.Controls.Clear();//移除所有控件
tcpServer.TopLevel = false;
tcpServer.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;
panel_Container.Width = tcpServer.Width;
tcpServer.Dock = DockStyle.Fill;
panel_Container.Controls.Add(tcpServer);
tcpServer.Show();
// 日志目录创建
String directoryPath = "log";
if (!Directory.Exists(directoryPath))
{
Directory.CreateDirectory(directoryPath);
//Console.WriteLine("目录已创建: " + directoryPath);
}
else
{
//Console.WriteLine("目录已存在: " + directoryPath);
}
}
/// <summary>
/// 窗体关闭，关闭服务端、客户端
/// </summary>
private void MainForm_FormClosing(object sender, FormClosingEventArgs e)
{
tcpClient?.Close();
tcpServer?.Close();
}
private void server_btn_Click(object sender, EventArgs e)
{
if (tcpServer == null)
{
tcpServer = new Frm_TcpServer();
}
panel_Container.Controls.Clear();//移除所有控件
tcpServer.TopLevel = false;
tcpServer.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;
panel_Container.Width = tcpServer.Width;
tcpServer.Dock = DockStyle.Fill;
panel_Container.Controls.Add(tcpServer);
tcpServer.Show();
}
private void client_btn_Click(object sender, EventArgs e)
{
if (tcpClient == null)
{
tcpClient = new Frm_TcpClient();
}
panel_Container.Controls.Clear();//移除所有控件
tcpClient.TopLevel = false;
tcpClient.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;
panel_Container.Width = tcpClient.Width;
tcpClient.Dock = DockStyle.Fill;
panel_Container.Controls.Add(tcpClient);
tcpClient.Show();
}
private void ServerToolStripMenuItem_Click(object sender, EventArgs e)
{
labelTitle.Text = "接推服务端";
if (tcpServer == null)
{
tcpServer = new Frm_TcpServer();
}
panel_Container.Controls.Clear();//移除所有控件
tcpServer.TopLevel = false;
tcpServer.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;
panel_Container.Width = tcpServer.Width;
tcpServer.Dock = DockStyle.Fill;
panel_Container.Controls.Add(tcpServer);
tcpServer.Show();
}
private void ClientToolStripMenuItem_Click(object sender, EventArgs e)
{
labelTitle.Text = "模拟客户端";
if (tcpClient == null)
{
tcpClient = new Frm_TcpClient();
}
panel_Container.Controls.Clear();//移除所有控件
tcpClient.TopLevel = false;
tcpClient.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;
panel_Container.Width = tcpClient.Width;
tcpClient.Dock = DockStyle.Fill;
panel_Container.Controls.Add(tcpClient);
tcpClient.Show();
}
private void AboutToolStripMenuItem_Click(object sender, EventArgs e)
{
Frm_about dialog = new Frm_about(); //
dialog.ShowDialog(); // 使用ShowDialog()方法显示对话框，这会阻止代码继续执行直到对话框关闭
}
}
}6. 入库主程序-Program
using System;
using System.Windows.Forms;
namespace JoTcp
{
internal static class Program
{
/// <summary>
/// 应用程序的主入口点。
/// </summary>
[STAThread]
static void Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new MainForm());
}
}
}
四、关于配置文件
本程序采用了自定义的INI单层配置方案，在config.ini中直接配置以下参数：
## 配置 ip=127.0.0.1 port=9001 apiurl=https://api.2om.cn/ceshi
五、使用场景 & 实测效果
物联网设备测试：和 PLC、传感器建立 TCP 连接，实时接收设备数据并推送到云平台，验证设备稳定性。
服务端日志转发：接收 Windows/Linux 服务器的 TCP 日志流，推送到 ELK 等日志分析平台，无需手动采集。
.NET 项目数据上报：本地.NET 程序生成的数据通过 TCP 发送，工具自动转发到业务 API，简化项目开发。
实测效果（.NET 4.7 + Windows 10）：
- 数据处理能力：每秒 150 + 条 TCP 数据，API 推送无阻塞
- 重连稳定性：断网后 5 秒自动重连，恢复后无缝续传
- 推送可靠性：API 临时不可用时，重试 3 次后仍失败会记录日志，避免数据丢失
