如何通过C＃显示特定服务的服务启动模式 [英] How to display Service Start Mode for a specific service thru C#

问题描述

您好

我正试图找到一种方法，只需显示特定

Windows服务的启动模式。例如...如果我只想点击一个按钮并让它显示W3SVC的服务状态和启动类型？

我尝试使用Servicecontroller但是这并没有给我这个选项。有没有一种简单的方法呢？

解决方案

基本上，您需要打开服务管理，与管理员一起打开服务，然后更改配置。三个步骤：

< a href =http://msdn.microsoft.com/en-us/library/windows/desktop/ms684330%28v=vs.85%29.aspx> http://msdn.microsoft.com/en-us /library/windows/desktop/ms684330%28v=vs.85%29.aspx [ ^ ]，

http://msdn.microsoft.com/en-us/library/windows/desktop/ms681987%28v=vs .85％29.aspx [ ^ ]。



第一步，使用 OpenSCManager获取服务管理器的句柄 SC_HANDLE code>，然后，第二步，使用它作为调用 OpenService 的第一个参数，然后，最后，使用生成的服务句柄，到调用 ChangeServiceConfig 。



你需要P / Invoke。如果您需要学习P / Invoke，请从这里开始：

http：//en.wikipedia .org / wiki / P / Invoke [ ^ ]，

http://msdn.microsoft.com/en-us/library / Aa712982 [ ^ ]。



此CodeProject也很有用： Essential P / Invoke [ ^ ]。



P / Invoke的一种替代方法是使用C ++ / CLI混合模式（托管+非托管）项目。此项目可以构建全局钩子所需的DLL，但它可以包含一些托管包装器CLI代码，因此，从.NET应用程序的角度来看，您可以将其用作常规.NET程序集，即引用它。请参阅：

http://en.wikipedia.org/wiki/C ％2B％2B / CLI [ ^ ]，

http：//www.ecma-international .org / publications / standards / Ecma-372.htm [ ^ ]，

http：/ /msdn.microsoft.com/en-us/library/xey702bw.aspx [ ^ ]，

http：/ /msdn.microsoft.com/en-us/library/3bstk3k5 [ ^ ]。



这样，y你可以用C ++编写代码，将它包装在C ++ / CLI托管类中，并将生成的模块作为.NET程序集引用。

顺便提一下，解决方案1的一个非常原始的替代方案：通过 System.Diagnostics.Process.Start使用SC.EXE（服务控制管理器） ：

 System.ServiceProcess.ServiceStartMode startMode =  / /   ...  
  string  processName =  //   ...  
 
  //   ...  
 
  string  application =   SC; 
  string  commandLine =  string  .Format（
   CONFIG {0}，start = {1}， //   important：'='之后的空格 
 processName，startMode）; 
 System.Diagnostics.Process.Start（application，commandLine）; 

您还可以重定向流 StandardOutput 以捕获应用程序的输出。为了以防万一，还重定向 StandardError 。你会在这里找到重定向的代码示例：

Hello
I am trying to find a way to just simply display the Start Mode for a specific
Windows Services. For example...If I just want to click on a button and have it display the Service Status and Start Type for W3SVC ?
I tried using Servicecontroller but that does not give me this option. Is there a simple way of doing this?

解决方案

Basically, you need to open service manages, with the manager, open a service, and then change it configuration. Three steps:
http://msdn.microsoft.com/en-us/library/windows/desktop/ms684323%28v=vs.85%29.aspx[^],
http://msdn.microsoft.com/en-us/library/windows/desktop/ms684330%28v=vs.85%29.aspx[^],
http://msdn.microsoft.com/en-us/library/windows/desktop/ms681987%28v=vs.85%29.aspx[^].

By first step, you get the handle of the Service Manager, SC_HANDLE, using OpenSCManager, then, by second step, use it as a first parameter for the call to OpenService and then, finally, use the resulting handle to the service, to call ChangeServiceConfig.

You will need P/Invoke. If you need to learn P/Invoke, start from here:
http://en.wikipedia.org/wiki/P/Invoke[^],
http://msdn.microsoft.com/en-us/library/Aa712982[^].

This CodeProject can also be useful: Essential P/Invoke[^].

One alternative to P/Invoke is to use C++/CLI mixed-mode (managed+unmanaged) project. This project could build a DLL required by the global hooks, but it can contain some managed wrapper CLI code, so, from the standpoint of your .NET application, you can use it as a regular .NET assembly, that is, reference it. Please see:
http://en.wikipedia.org/wiki/C%2B%2B/CLI[^],
http://www.ecma-international.org/publications/standards/Ecma-372.htm[^],
http://msdn.microsoft.com/en-us/library/xey702bw.aspx[^],
http://msdn.microsoft.com/en-us/library/3bstk3k5[^].

This way, you can write the code in C++, wrap it in C++/CLI managed class and reference the resulting module as a .NET assembly.

By the way, one extremely primitive alternative to Solution 1: use "SC.EXE" (Service Control Manager) via System.Diagnostics.Process.Start:

System.ServiceProcess.ServiceStartMode startMode = // ...
string processName = // ...

//...

string application = "SC";
string commandLine = string.Format(
    "CONFIG {0}, start= {1}", // important: blank space after '='
    processName, startMode);
System.Diagnostics.Process.Start(application, commandLine);

You can also redirect the stream StandardOutput to capture output of the application. Just in case, redirect also StandardError. You will find the code sample for redirection here:
http://msdn.microsoft.com/en-us/library/system.diagnostics.process.standardoutput.aspx[^].
