本随笔提供了一个有用的Windows服务小程序的主要是Server端的Socket通信服务。本人也不是非常熟悉Windows服务和Socket通信的知识,但是经过了一天的不懈努力还是了解和学习了一些这方面的皮毛,还望知道这方面知识的博友不吝赐教。
今天被迫要做一个接收通信的模块,以前从来都没有做过关于通信方面的东西,就像没有做过有关GIS方面的程序一样是头一次开发此类程序。
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:
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:
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:
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:
本地下载 SocketLibrary类库源码
本地下载 Server端Socket通信Windows服务源码
本地下载 SocketClientTest源码
本地下载 SocketServerTest源码(没有改变为Windows服务时的程序,即下载时的原程序)
以上程序已在Visual Studio.Net2003下运行通过。
备注:下面有本人的两个评论来修正本随笔中的代码存在的一些问题,请仔细浏览,谢谢浏览本随笔……

SocketFactory.cs文件代码
using System;
using System.Net;
using System.Net.Sockets;
namespace SocketLibrary {
/**//// <summary>
/// 网络通信组件
/// </summary>
public class SocketFactory {
public static System.Text.Encoding DefaultEncoding = System.Text.Encoding.GetEncoding("GB2312");
}
}
4、将文件和代码建立和粘贴完成后,运行此类库,会在程序所在路径文件夹里的“bin\Debug\”下找到“SocketLibrary.dll”文件,下面开发的Windows服务就需要引用这个dll文件。using System;
using System.Net;
using System.Net.Sockets;
namespace SocketLibrary {
/**//// <summary>
/// 网络通信组件
/// </summary>
public class SocketFactory {
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:

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:
CForm.cs文件代码
using System;
using System.Drawing;
using System.Collections;
using System.ComponentModel;
using System.Windows.Forms;
using System.Data;
namespace SocketClientTest
{
/**//// <summary>

{
/**//// <summary>

public CForm()
{
//
// Windows 窗体设计器支持所必需的
//
InitializeComponent();
//
// TODO: 在 InitializeComponent 调用后添加任何构造函数代码
//
}
/**//// <summary>
/// 清理所有正在使用的资源。
/// </summary>
protected override void Dispose( bool disposing )
{
if( disposing )
{
if (components != null)
{
components.Dispose();
}
}
base.Dispose( disposing );
}

}

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。using System;

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:
本地下载 SocketLibrary类库源码
本地下载 Server端Socket通信Windows服务源码
本地下载 SocketClientTest源码
本地下载 SocketServerTest源码(没有改变为Windows服务时的程序,即下载时的原程序)
以上程序已在Visual Studio.Net2003下运行通过。
