今天決定寫(xiě)寫(xiě)博客，不為別的，只當(dāng)自己的積累，如果與此同時(shí)能不誤導(dǎo)他人甚至給了朋友們一些啟發(fā)，那真是更好了！

程序的目的和用途：

很多開(kāi)機(jī)啟動(dòng)程序僅僅加在啟動(dòng)項(xiàng)里面，只有登陸后才真正啟動(dòng)。windows服務(wù)在開(kāi)機(jī)未進(jìn)行用戶(hù)登錄前就啟動(dòng)了。正是利用這一點(diǎn)，解決一些服務(wù)器自動(dòng)重啟后特定軟件也自動(dòng)啟動(dòng)的問(wèn)題。

1.新建一個(gè)服務(wù)項(xiàng)目 visual C#----windows----windows服務(wù)；

2.添加一個(gè)dataset（.xsd）,用于存儲(chǔ)啟動(dòng)目標(biāo)的路徑，日志路徑等。

?? 在dataset可視化編輯中，添加一個(gè)datatable，包含兩列 StartAppPath 和 LogFilePath。分別用于存儲(chǔ)目標(biāo)的路徑、日志路徑。

?? *我認(rèn)為利用dataset.xsd存儲(chǔ)配置參數(shù)的優(yōu)勢(shì)在于可以忽略xml解析的具體過(guò)程直接使用xml文件。

???? 在dataset中 提供了ReadXml方法用于讀取xml文件并將其轉(zhuǎn)換成內(nèi)存中的一張datatable表，數(shù)據(jù)很容易取出來(lái)！同樣，WriteXml方法用于存儲(chǔ)為xml格式的文件，也僅僅需要一句話(huà)而已。

3. program.cs文件 作為程序入口，代碼如下：

view plaincopy to clipboardprint?
using System.Collections.Generic;??
using System.ServiceProcess;??
using System.Text;??
??
namespace WindowsServices_AutoStart??
{??
????static class Program??
????{??
????????/// <summary>??
????????/// 應(yīng)用程序的主入口點(diǎn)。??
????????/// </summary>??
????????static void Main()??
????????{??
????????????ServiceBase[] ServicesToRun;??
??
????????????// 同一進(jìn)程中可以運(yùn)行多個(gè)用戶(hù)服務(wù)。若要將??
????????????// 另一個(gè)服務(wù)添加到此進(jìn)程中，請(qǐng)更改下行以??
????????????// 創(chuàng)建另一個(gè)服務(wù)對(duì)象。例如，??
????????????//??
????????????//?? ServicesToRun = new ServiceBase[] {new Service1(), new MySecondUserService()};??
????????????//??
????????????ServicesToRun = new ServiceBase[] { new WindowsServices_AutoStart() };??
??
????????????ServiceBase.Run(ServicesToRun);??
????????}??
????}??
}??
using System.Collections.Generic;
using System.ServiceProcess;
using System.Text;

namespace WindowsServices_AutoStart
{
????static class Program
????{
????????/// <summary>
????????/// 應(yīng)用程序的主入口點(diǎn)。
????????/// </summary>
????????static void Main()
????????{
????????????ServiceBase[] ServicesToRun;

????????????// 同一進(jìn)程中可以運(yùn)行多個(gè)用戶(hù)服務(wù)。若要將
????????????// 另一個(gè)服務(wù)添加到此進(jìn)程中，請(qǐng)更改下行以
????????????// 創(chuàng)建另一個(gè)服務(wù)對(duì)象。例如，
????????????//
????????????//?? ServicesToRun = new ServiceBase[] {new Service1(), new MySecondUserService()};
????????????//
????????????ServicesToRun = new ServiceBase[] { new WindowsServices_AutoStart() };

????????????ServiceBase.Run(ServicesToRun);
????????}
????}
}

5.啟動(dòng)調(diào)試，成功時(shí)也會(huì)彈出一個(gè)對(duì)話(huà)框大致意思是提示服務(wù)需要安裝。

6.把Debug文件夾下面的.exe執(zhí)行程序，安裝為windows系統(tǒng)服務(wù)，安裝方法網(wǎng)上很多介紹。我說(shuō)一種常用的：

安裝服務(wù)
訪(fǎng)問(wèn)項(xiàng)目中的已編譯可執(zhí)行文件所在的目錄。??
用項(xiàng)目的輸出作為參數(shù)，從命令行運(yùn)行 InstallUtil.exe。在命令行中輸入下列代碼：??
installutil yourproject.exe
卸載服務(wù)??
用項(xiàng)目的輸出作為參數(shù)，從命令行運(yùn)行 InstallUtil.exe。??
installutil /u yourproject.exe

至此，整個(gè)服務(wù)已經(jīng)編寫(xiě)，編譯，安裝完成，你可以在控制面板的管理工具的服務(wù)中，看到你編寫(xiě)的服務(wù)。

7.安裝好了之后在系統(tǒng)服務(wù)列表中可以管理服務(wù)，這時(shí)要注意將服務(wù)的屬性窗口----登陸----“允許于桌面交互”勾選！這樣才能在啟動(dòng)了你要的目標(biāo)程序后不單單存留于進(jìn)程。在桌面上也看得到。

8.關(guān)于卸載服務(wù)，目前有兩個(gè)概念：一是禁用而已；一是完全刪除服務(wù)。 前者可以通過(guò)服務(wù)管理窗口直接完成。后者則需要進(jìn)入注冊(cè)表“HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services”找到服務(wù)名稱(chēng)的文件夾，整個(gè)刪掉，重新啟動(dòng)電腦后，服務(wù)消失。

9.擴(kuò)展思考：經(jīng)過(guò)修改代碼，還可以實(shí)現(xiàn)：啟動(dòng)目標(biāo)程序之前，檢測(cè)進(jìn)程中是否存在目標(biāo)程序，存在則不再次啟動(dòng)
