windows服务开发（一、安装）-CFANZ编程社区

最近由于工作需要，写了一个windows服务程序，有许多经验，我会陆续写出来。
请原谅我从安装谈起，因为我一直有一个误区：只要从System.ServiceProcess.ServiceBase继承一个类并编译好就可以用.net提供的命令行程序InstallUtil.exe安装了。经过尝试，发现如果仅仅做了这样的一个类是无法用InstallUtil.exe安装的，在安装时会输出下面的信息：
D:\>installutil windowsservice2.exe
Microsoft (R) .NET Framework Installation utility Version 1.1.4322.573
Copyright (C) Microsoft Corporation 1998-2002. All rights reserved.
Running a transacted installation.

Beginning the Install phase of the installation.
See the contents of the log file for the d:\windowsservice2.exe assembly's progr
ess.
The file is located at d:\windowsservice2.InstallLog.
Installing assembly 'd:\windowsservice2.exe'.
Affected parameters are:
assemblypath = d:\windowsservice2.exe
logfile = d:\windowsservice2.InstallLog
No public installers with the RunInstallerAttribute.Yes attribute could be found
in the d:\windowsservice2.exe assembly.

The Install phase completed successfully, and the Commit phase is beginning.
See the contents of the log file for the d:\windowsservice2.exe assembly's progr
ess.
The file is located at d:\windowsservice2.InstallLog.
Committing assembly 'd:\windowsservice2.exe'.
Affected parameters are:
assemblypath = d:\windowsservice2.exe
logfile = d:\windowsservice2.InstallLog
No public installers with the RunInstallerAttribute.Yes attribute could be found
in the d:\windowsservice2.exe assembly.
Remove InstallState file because there are no installers.

The Commit phase completed successfully.

The transacted install has completed.
这是因为installUtil.exe会用反射的方法去查找所有把RunInstallerAttribute设置为true的System.Configuration.Install.Installer类型，并执行上面的Install方法，当找不到的时候，安装就失败了。
所以我们必须要写一个从Installer类继承的类来满足installUtil.exe的要求。

由于windows服务的特殊性，其调试和通常的程序调试有一定的差别，下面我分别介绍几种方法：
1、微软推荐的方法
1.1、调试windows服务的初始化、启动
另写一个程序控制服务的初始化和启动

1.2、调试windows服务的其他方面
就是附加到操作系统进程的方法

2、我的trace方法
2.1、添加调试方法

private static void DebugRun(string[] args) 
 { 
 
 /*
 初始化服务
 OnStart();
 Console.ReadLine();
 OnStop();
 */
 }

2.2、改写程序入口为如下：

public static void Main(string[] args)
  { 
 
 #if DEBUG
 DebugRun(args);
 #else
 /*
 初始化服务
 */
 #endif
 }

2.3、加入2种调试代码

EventLog.WriteEntry("...");
 System.Diagnostics.Debug.WriteLine("...");
