TCP/IP以及Socket聊天室带类库源码分享
最近遇到个设备，需要去和客户的软件做一个网络通信交互，一般的我们的上位机都是作为客户端来和设备通信的，这次要作为服务端来监听客户端，在这个背景下，我查阅了一些大佬们的博客，和一些资料。将这些汇总做了一个简单的服务端监听和客户端的类库，希望对大家有一定的作用，当然更多还是给自己做一个日记。下面是类库和对类库测试的一些全部源代码，有需要的可以我QQ获取源代码（674479991）。
1.通信类库
using System;
using System.Collections.Generic;
using System.Text;
using System.Net;
using System.Net.Sockets;
namespace TCP_DLL

/// <summary>

cilentList.Add(info, ConnCilent);
retn = info + "接入服务成功！";
}
return true;

return true;

2.服务端源代码和界面
using System;
using System.Threading.Tasks;
using System.Windows.Forms; namespace ServerTest
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private TCP_DLL.PSS_Server Server;
private void textBox3_KeyDown(object sender, KeyEventArgs e)
{
if (e.KeyCode == Keys.Enter)
{
if (Server.SendMsg(textBox3.Text).Equals(false))
{
MessageBox.Show("发送消息失败！！");
return;
}
textBox3.Clear();
}
} private void button1_Click(object sender, EventArgs e)
{
string retn = "";
Server = new TCP_DLL.PSS_Server(textBox1.Text, int.Parse(textBox2.Text));
textBox4.Invoke(new Action(() => textBox4.AppendText(DateTime.Now + "\r\n" + "创建服务完成，等待接入..." + "\r\n"))); if (Server.Accept(ref retn).Equals(false))
{
MessageBox.Show(retn);
return;
}
textBox4.Invoke(new Action(() => textBox4.AppendText(DateTime.Now + "\r\n" + retn + "\r\n"))); Task.Factory.StartNew(() =>
{
while (true)

{
MessageBox.Show("接收消息异常！！");
return;
}
textBox4.Invoke(new Action(() => textBox4.AppendText(DateTime.Now + "\r\n" + retn + "\r\n")));
}
});
} private void button2_Click(object sender, EventArgs e)
{
Server.Close();
}
}
}
2.客户端界面和源代码
using System;
using System.Threading.Tasks;
using System.Windows.Forms; namespace CilentTest
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private TCP_DLL.PSS_Cilent Cilent = new TCP_DLL.PSS_Cilent(); private void textBox3_KeyDown(object sender, KeyEventArgs e)
{

{
MessageBox.Show("发送消息失败！！！");
return;
}
textBox3.Clear();
}
} private void button1_Click(object sender, EventArgs e)
{
if (Cilent.Connect(textBox1.Text,int.Parse(textBox2.Text)).Equals(false))
{
MessageBox.Show("连接失败！！！");
return;
}
textBox4.Invoke(new Action(() => textBox4.AppendText(DateTime.Now + "\r\n" + "创建连接完成....." + "\r\n")));
Task.Factory.StartNew(() =>

while (true)
