这个Socket通信说是自己的其实完全不是（如果哪位高人见到此程序是您本人开发的千万不要介意，本人也是在网上搜索出的，这个程序真的很不错，值得推广哦！在此谢谢发布此Socket通信程序的高人）。
此程序的大部分源码没有任何改动，只是原来的Server端是用C/S程序写的，为了能使Socket通信的Server端更灵活，在此将其改成一个Windows服务，因此也需要改动了一些Server端的代码和工程，但是基础类和Client端都没有改变。
对于我本人来说，Windows服务和Socket通信本人都不是很了解，只是经过了昨天简单的学习和研究才完成了此Windows服务Server端Socket通信程序，所以也说不出太多的门道，如果有清楚这方面知识的博友还希望能多多交流。好了，废话少说，开始正题了。
现在开始我们来讲解，如何一步一步地完成Windows服务Server端Socket通信程序。
我个人认为Windows服务只是包裹在Socket通信程序外的“一件外套”，所以核心还是我在网上找到的这个Socket程序，为此我们的第一步应该先开发出此Socket程序的类库。
1、打开Visual Studio.Net2003，单击菜单中的“文件”——>“新建”——>“项目”，在弹出的对话框左侧选择“Visual C#项目”，在右侧选择“类库”，下方的名称中输入“SocketLibrary”，位置自己随便选择一个路径。
2、删除自动创建的Class1.cs，新建如下的类名文件“Client.cs”、“Connection.cs”、“ConnectionCollection.cs”、“Message.cs”、“MessageCollection.cs”、“Server.cs”、“SocketBase.cs”和“SocketFactory.cs”。
3、各个类文件的代码如下：
(1)、Client.cs文件中的代码：
using System;
using System.Net;
using System.Net.Sockets;
namespace SocketLibrary
{
public class Client:SocketBase
{
public const int CONNECTTIMEOUT = 10;
public Client()
{
}
public Connection StartClient(IPAddress ipaddress,int port) {
TcpClient client = new TcpClient();
client.SendTimeout = CONNECTTIMEOUT;
client.ReceiveTimeout = CONNECTTIMEOUT;
client.Connect(ipaddress,port);
this._connections.Add(new Connection(client.GetStream()));
this.StartListenAndSend();
return new Connection(client.GetStream());
}
public void StopClient() {
this.EndListenAndSend();
}
}
}

public static System.Text.Encoding DefaultEncoding = System.Text.Encoding.GetEncoding("GB2312");
}
}
第二步再来开发出Windows服务。
1、打开Visual Studio.Net2003，单击菜单中的“文件”——>“新建”——>“项目”，在弹出的对话框左侧选择“Visual C#项目”，在右侧选择“Windows服务”，下方的名称中输入“SocketService”，位置自己随便选择一个路径。
2、删除自动创建的服务文件，新建如下的Windows服务文件“SocketService.cs”。
3、在SocketService.cs文件的设计界面，选择开发环境右侧的“属性”页卡，会在页卡底部发现“添加安装程序(I)”，单击此处后会在解决方案的SocketService工程下多一个服务文件“ProjectInstaller.cs”。
4、在ProjectInstaller.cs文件的设计界面，会看见两个组件“serviceProcessInstaller1”和“serviceInstaller1”。将serviceProcessInstaller1组件的Account属性设置为“LocalSystem”（表示本地系统服务，NetworkService表示网络服务，LocalService表示本地服务，User表示用户服务）；再将serviceInstaller1组件的StartType属性设置为“Automatic”（表示服务自动启动，Manual表示手动启动，Disabled表示禁用）。
5、右击解决方案中的“引用”，选择添加引用，在弹出的对话框中选择“浏览”，将前面的“SocketLibrary.dll”添加到此引用。
6、在系统C盘下建立两个文件“SocketService.ini”和“SocketService.log”。SocketService.ini文件是配置SocketService监听的端口号，打开该ini文件在其中编辑下面的内容“端口号：8088”（双引号请不要输入在ini文件的内容里），而SocketService.log是为了记录有关信息的日志。
7、删除SocketService.cs文件的所有代码，将下面的代码拷贝到该文件中：
using System;
using System.Collections;
using System.ComponentModel;
using System.Data;
using System.Diagnostics;
using System.ServiceProcess;
using System.IO;
using SocketLibrary;
namespace SocketService
{
public class SocketService : System.ServiceProcess.ServiceBase

}
#endregion

{

}

{
System.ServiceProcess.ServiceBase.Run(new SocketService());
}
SocketLibrary.Server _server = new SocketLibrary.Server();
/**//// <summary>

protected override void OnStart(string[] args)
{
// TODO: 在此处添加代码以启动服务。
try
{
StreamReader ConfigReader = new StreamReader("C:\\SocketService.ini",System.Text.Encoding.GetEncoding("GB2312"));
string str = ConfigReader.ReadToEnd();
string[] Str = str.Split('：');
if (Str.Length == 2)
{
if(Str[0] == "端口号")
{
_server.StartServer(Convert.ToInt32(Str[1]));
StreamWriter LogWriter = new StreamWriter("C:\\SocketService.log",true,System.Text.Encoding.GetEncoding("GB2312"));
LogWriter.Write(DateTime.Now.ToLongDateString() + " " + DateTime.Now.ToShortTimeString() + " SocketService服务已启动\n");
LogWriter.Close();
_server.MessageReceived += new SocketLibrary.SocketBase.MessageEventHandler(_server_MessageReceived);
_server.Connected += new SocketLibrary.SocketBase.ConnectionHandler(_server_Connected);
}
else
{
StreamWriter LogWriter = new StreamWriter("C:\\SocketService.log",true,System.Text.Encoding.GetEncoding("GB2312"));
LogWriter.Write(DateTime.Now.ToLongDateString() + " " + DateTime.Now.ToShortTimeString() + " SocketService.ini文件中无端口号属性，格式应为\"端口号：[输入的端口号]\"\n");
LogWriter.Close();
OnStop();
}
}
else
{

}
}

{

LogWriter.Write(DateTime.Now.ToLongDateString() + " " + DateTime.Now.ToShortTimeString() + " SocketService服务启动时有错误，错误信息：" + e.Message + "\n");
LogWriter.Close();
OnStop();
}
}
/**//// <summary>

/// </summary>
protected override void OnStop()
{
// TODO: 在此处添加代码以执行停止服务所需的关闭操作。
_server.StopServer();
StreamWriter LogWriter = new StreamWriter("C:\\SocketService.log",true,System.Text.Encoding.GetEncoding("GB2312"));
LogWriter.Write(DateTime.Now.ToLongDateString() + " " + DateTime.Now.ToShortTimeString() + " SocketService服务已停止\n");
LogWriter.Close();
}
private void _server_MessageReceived(object sender, SocketLibrary.SocketBase.MessageEventArgs e)
{
StreamWriter LogWriter = new StreamWriter("C:\\SocketService.log",true,System.Text.Encoding.GetEncoding("GB2312"));

LogWriter.Write(DateTime.Now.ToLongDateString() + " " + DateTime.Now.ToShortTimeString() + " " + e.Exception.Message + "\n");
LogWriter.Close();
}
}
}
8、在Visual Studio.Net2003的菜单上选择“生成”——>“重新生成解决方案”，当生成成功后，会在程序所在路径文件夹里的“bin\Debug\”下找到“SocketService.exe”文件，记住这个路径和文件名，下一步需要用到。
9、打开“Visual Studio .NET 2003 命令提示”（应该都知道如何打开吧，不知道的可以在评论中询问）。在其中输入“installutil [第8步中的路径和文件名]”（例如：installutil C:\SocketService\bin\Debug\SocketService.exe），按下回车，将会在本机上安装刚开发好的Windows服务，如果要卸载安装过的Windows服务请在“Visual Studio .NET 2003 命令提示”中输入“installutil /u [第8步中的路径和文件名]”（例如：installutil /u C:\SocketService\bin\Debug\SocketService.exe）。
10、制作Windows服务的安装部署工程（略）。
第三步最后开发出一个Socket通信的客户端来验证此服务。
1、和以往建立C/S程序的过程一样，只是将工程名称改为“SocketClientTest”。
2、删除自动创建的Form1，新建窗体“CFrom”。
3、窗体控件与布局见下图：
4、在引用中添加“SocketLibrary.dll”引用（添加方法和SocketService工程添加方法相同）
5、后台代码如下：
using System;
using System.Drawing;
using System.Collections;
using System.ComponentModel;
using System.Windows.Forms;
using System.Data;
namespace SocketClientTest
{
/**//// <summary>

/**//// <summary>

6、运行程序，点击CForm中的“连接”按钮，再在TextBox1中输入部分信息，单击“发送”按钮，看看在C:\SocketService.log中是否记录了CForm窗口中TextBox1中的内容。
到此我们就已经将这个Socket通信Server端的Winodows服务开发完成了。下面提供源程序的下载：

以上程序已在Visual Studio.Net2003下运行通过。
