使用 InstallUtil 解除安裝不存在的服務
我正在使用我的服務的建構前和建構後事件來解除安裝和安裝服務。唯一的問題是,另一個開發人員第一次使用預建構事件時它會失敗,因為該服務尚未安裝。
我目前解除安裝的預建構事件是
%WinDir%\Microsoft.NET\Framework\v4.0.30319\InstallUtil /u $(TargetPath)當服務已經安裝時,我如何才能使用它來解除安裝?
您可以使用 Microsoft SC 工具 (Sc.exe) 來查詢服務的狀態,甚至可以創建或刪除服務。這裡有一篇關於這個命令使用的文章:http: //support.microsoft.com/kb/251192
從命令提示符視窗(為強調而編輯的內容):
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).執行此命令來查詢 (A) 存在且 (B) 不存在的服務會導致:
(一個)
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(乙)
C:\Windows\System32>sc query nothere [SC] EnumQueryServicesStatus:OpenService FAILED 1060: The specified service does not exist as an installed service.因此,您可以在嘗試使用以下命令刪除服務之前測試它是否存在——(請原諒對 FOR 語句的排斥使用,我不確定如何將 sc 命令的輸出擷取到變數中或在 IF 語句中使用它)-
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%
