一、开发环境
操作系统：Windows 10 X64
开发环境：VS2015
编程语言：C#
.NET版本：.NET Framework 4.0
目标平台：X86
二、创建Windows Service
1、新建一个Windows Service，并将项目名称改为“MyWindowsService”，如下图所示：
2、在解决方案资源管理器内将Service1.cs改为MyService1.cs后并点击“查看代码”图标按钮进入代码编辑器界面，如下图所示：
3、在代码编辑器内如入以下代码，如下所示：
using System; using System.ServiceProcess; using System.IO;namespace MyWindowsService
{
public partial class MyService : ServiceBase
{
public MyService()
{
InitializeComponent();
}</span><span style="color: rgba(0, 0, 255, 1)">string</span> filePath = <span style="color: rgba(128, 0, 0, 1)">@"</span><span style="color: rgba(128, 0, 0, 1)">D:\MyServiceLog.txt</span><span style="color: rgba(128, 0, 0, 1)">"</span><span style="color: rgba(0, 0, 0, 1)">; </span><span style="color: rgba(0, 0, 255, 1)">protected</span> <span style="color: rgba(0, 0, 255, 1)">override</span> <span style="color: rgba(0, 0, 255, 1)">void</span> OnStart(<span style="color: rgba(0, 0, 255, 1)">string</span><span style="color: rgba(0, 0, 0, 1)">[] args) { </span><span style="color: rgba(0, 0, 255, 1)">using</span> (FileStream stream = <span style="color: rgba(0, 0, 255, 1)">new</span><span style="color: rgba(0, 0, 0, 1)"> FileStream(filePath,FileMode.Append)) </span><span style="color: rgba(0, 0, 255, 1)">using</span> (StreamWriter writer = <span style="color: rgba(0, 0, 255, 1)">new</span><span style="color: rgba(0, 0, 0, 1)"> StreamWriter(stream)) { writer.WriteLine($</span><span style="color: rgba(128, 0, 0, 1)">"</span><span style="color: rgba(128, 0, 0, 1)">{DateTime.Now},服务启动！</span><span style="color: rgba(128, 0, 0, 1)">"</span><span style="color: rgba(0, 0, 0, 1)">); } } </span><span style="color: rgba(0, 0, 255, 1)">protected</span> <span style="color: rgba(0, 0, 255, 1)">override</span> <span style="color: rgba(0, 0, 255, 1)">void</span><span style="color: rgba(0, 0, 0, 1)"> OnStop() { </span><span style="color: rgba(0, 0, 255, 1)">using</span> (FileStream stream = <span style="color: rgba(0, 0, 255, 1)">new</span><span style="color: rgba(0, 0, 0, 1)"> FileStream(filePath, FileMode.Append)) </span><span style="color: rgba(0, 0, 255, 1)">using</span> (StreamWriter writer = <span style="color: rgba(0, 0, 255, 1)">new</span><span style="color: rgba(0, 0, 0, 1)"> StreamWriter(stream)) { writer.WriteLine($</span><span style="color: rgba(128, 0, 0, 1)">"</span><span style="color: rgba(128, 0, 0, 1)">{DateTime.Now},服务停止！</span><span style="color: rgba(128, 0, 0, 1)">"</span><span style="color: rgba(0, 0, 0, 1)">); } } }}
4、双击项目“MyWindowsService”进入“MyService”设计界面，在空白位置右击鼠标弹出上下文菜单，选中“添加安装程序”，如下图所示：
5、此时软件会生成两个组件，分别为“serviceInstaller1”及“serviceProcessInstaller1”，如下图所示：
6、点击“serviceInstaller1”，在“属性”窗体将ServiceName改为MyService，Description改为我的服务，StartType保持为Manual，如下图所示：
7、点击“serviceProcessInstaller1”，在“属性”窗体将Account改为LocalSystem（服务属性系统级别），如下图所示：
8、鼠标右键点击项目“MyWindowsService”，在弹出的上下文菜单中选择“生成”按钮，如下图所示：
9、至此，Windows服务已经创建完毕。
三、创建安装、启动、停止、卸载服务的Windows窗体
1、在同一个解决方案里新建一个Windows Form项目，并命名为WindowsServiceClient，如下图所示：
2、将该项目设置为启动项目，并在窗体内添加四个按钮，分别为安装服务、启动服务、停止服务及卸载服务，如下图所示：
3、按下F7进入代码编辑界面，引用“System.ServiceProcess”及“System.Configuration.Install”，并输入如下代码：
using System; using System.Collections; using System.Windows.Forms; using System.ServiceProcess; using System.Configuration.Install;namespace WindowsServiceClient
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
string serviceFilePath = $"{Application.StartupPath}\MyWindowsService.exe";
string serviceName = "MyService";</span><span style="color: rgba(0, 128, 0, 1)">//</span><span style="color: rgba(0, 128, 0, 1)">事件：安装服务</span> <span style="color: rgba(0, 0, 255, 1)">private</span> <span style="color: rgba(0, 0, 255, 1)">void</span> button1_Click(<span style="color: rgba(0, 0, 255, 1)">object</span><span style="color: rgba(0, 0, 0, 1)"> sender, EventArgs e) { </span><span style="color: rgba(0, 0, 255, 1)">if</span> (<span style="color: rgba(0, 0, 255, 1)">this</span>.IsServiceExisted(serviceName)) <span style="color: rgba(0, 0, 255, 1)">this</span><span style="color: rgba(0, 0, 0, 1)">.UninstallService(serviceName);

4、为了后续调试服务及安装卸载服务的需要，将已生成的MyWindowsService.exe引用到本Windows窗体，如下图所示：
5、由于需要安装服务，故需要使用UAC中Administrator的权限，鼠标右击项目“WindowsServiceClient”，在弹出的上下文菜单中选择“添加”->“新建项”，在弹出的选择窗体中选择“应用程序清单文件”并单击确定，如下图所示：
6、打开该文件，并将<requestedExecutionLevel level="asInvoker" uiAccess="false" />改为<requestedExecutionLevel level="requireAdministrator" uiAccess="false" />，如下图所示：
7、IDE启动后，将会弹出如下所示的窗体（有的系统因UAC配置有可能不显示），需要用管理员权限打开：
8、重新打开后，在IDE运行WindowsServiceClient项目；
9、使用WIN+R的方式打开运行窗体，并在窗体内输入services.msc后打开服务，如下图所示：
10、点击窗体内的“安装服务”按钮，将会在服务中出现MyService，如下图所示：
11、点击“运行服务”按钮，将启动并运行服务，如下所示：
12、点击“停止服务”按钮，将会停止运行服务，如下图所示：
13、点击“卸载服务”按钮，将会从服务中删除MyService服务。
14、以上启动及停止服务将会写入D:\MyServiceLog.txt，内容如下所示：

补充：如何调试服务
1、要调试服务，其实很简单，如需将服务附加进程到需要调试的项目里面即可，假如要调试刚才建的服务，现在OnStop事件里设置断点，如下所示：
2、启动“WindowsServiceClient”项目，在“调试”菜单中选择“附件到进程”（服务必须事先安装），如下所示：
3、找到“MyWindowsService.exe”，点击“附加”按钮，如下图所示：
4、点击“停止服务”按钮，程序将会在设置断点的地方中断，如下图所示：
