Question

我该如何进行for循环，以便像所显示的逻辑那样使用for循环迭代字符串值：

set list[0]="string1"
set list[1]="string2"
...
set list[10]="string10"

for n in list do (

   for /F "tokens=3 delims=: " %%H in ('sc query "list[n]" ^| findstr "        STATE"') do (   
      if /I "%%H" NEQ "RUNNING" (    
          net stop list[n]    
          net start list[n]   )   
      else( ) )
    )

Answer 1

将一些提示纳入代码中，

我在两个地方使用列表索引来克服可能的排序问题。
为了避免在“单个”命令中出现延迟扩展问题，我使用与初始化列表相同的方式枚举服务。
仅测试echo net stop / start命令。
因此我可以在系统中使用真实的服务名称。

:: Q:\Test\2018\07\25\SO_51512357.cmd
@Echo off&SetLocal EnableExtensions EnableDelayedExpansion

:: initialize/clear list
For /F "delims==" %%A in ('2^>Nul set list[') do Set "%%A="

:: use self expanding code to set list to array list[xx]
Set i=99
Set "list=,WPDBusEnum,WpnService,wscsvc,WSearch,wuauserv,WwanSvc"
Set "list=%list%,xbgm,XblAuthManager,XblGameSave,XboxGipSvc,XboxNetApiSvc"
Set "list=%list:,="&Set /a i+=1&Set "list[!i:~-2!]=%"
Set list

:: technically the following is one line, line breaks inserted where possible. 
For /F "tokens=2delims==" %%n in (
  '2^>Nul set list['
) do  for /F "tokens=3 delims=: " %%H in (
  'sc query "%%n" 2^>Nul ^| findstr /C:"        STATE              :"'
) do if /I "%%H" NEQ "RUNNING" (    
    echo net stop    %%n    
    echo net start   %%n
) else ( 
    echo svc running %%n
)

示例输出：

> Q:\Test\2018\07\25\SO_51512357.cmd
list[00]=WPDBusEnum
list[01]=WpnService
list[02]=wscsvc
list[03]=WSearch
list[04]=wuauserv
list[05]=WwanSvc
list[06]=xbgm
list[07]=XblAuthManager
list[08]=XblGameSave
list[09]=XboxGipSvc
list[10]=XboxNetApiSvc
net stop    WPDBusEnum
net start   WPDBusEnum
svc running WpnService
svc running wscsvc
svc running WSearch
net stop    wuauserv
net start   wuauserv
net stop    WwanSvc
net start   WwanSvc
net stop    xbgm
net start   xbgm
net stop    XblAuthManager
net start   XblAuthManager
net stop    XblGameSave
net start   XblGameSave
net stop    XboxGipSvc
net start   XboxGipSvc
net stop    XboxNetApiSvc
net start   XboxNetApiSvc
