我正在使用我的服务的pre和post构建事件来卸载和安装服务.唯一的问题是,第一次另一个开发人员使用预构建事件时它失败了,因为尚未安装该服务.
我卸载的当前预构建事件是
- %WinDir%\Microsoft.NET\Framework\v4.0.30319\InstallUtil /u $(TargetPath)
如何在服务已经安装时才使用它来卸载？
您可以使用Microsoft SC工具(Sc.exe)查询服务的状态,甚至可以创建或删除服务.这是一篇关于使用此命令的文章：
http://support.microsoft.com/kb/251192
- C:\windows\system32>sc
- DESCRIPTION:
- SC is a command line program used for communicating with the
- Service Control Manager and services.
- USAGE:
- sc <server> [command] [service name] <option1> <option2>...
- The option <server> has the form "\\ServerName"
- Further help on commands can be obtained by typing: "sc [command]"
- Commands:
- query-----------Queries the status for a service,or
- enumerates the status for types of services.
- queryex---------Queries the extended status for a service,or
- enumerates the status for types of services.
- start-----------Starts a service.
- pause-----------Sends a PAUSE control request to a service.
- continue--------Sends a CONTINUE control request to a service.
- stop------------Sends a STOP request to a service.
- delete----------Deletes a service (from the registry).
- create----------Creates a service. (adds it to the registry).
运行此命令以查询(A)存在且(B)不存在的服务导致：
(一个)
- C:\Windows\System32>sc query W32Time
- SERVICE_NAME: W32Time
- TYPE : 20 WIN32_SHARE_PROCESS
- STATE : 1 STOPPED
- WIN32_EXIT_CODE : 1077 (0x435)
- SERVICE_EXIT_CODE : 0 (0x0)
- CHECKPOINT : 0x0
- WAIT_HINT : 0x0
(B)
- C:\Windows\System32>sc query nothere
- [SC] EnumQueryServicesStatus:OpenService Failed 1060:
- The specified service does not exist as an installed service.
因此,您可以在尝试使用以下内容删除它之前测试服务的存在 – (原谅令人厌恶地使用FOR语句,我不确定如何将sc命令的输出捕获到变量或在IF声明中使用它) –
- set svcname=W32Time
- set svc=exists
- for /f "delims=" %%o in ('sc query %svcname% ^| find "FAIL"') do set svc=notexists
- if "%svc%"=="exists" sc delete %svcname%
