Batch file 如何打印数组元素并使用for循环遍历它们？

我正在处理批处理文件。我有一个数组：

setlocal enabledelayedexpansion
set Base_list[0]=Base1
set Base_list[1]=Base2
set Base_list[2]=Base3
set Base_list[3]=Base4
set Base_list[4]=Base5
set Base_list[5]=Base6
set Current_Node=Node1
if "%Current_Node%" == "Node1" ( for /l %%a in (0 ,%counter% , %Base_list%) do (
// do some stuff
)
)

如何打印名为

Base\u list

的数组

如何遍历此数组

我想，你完全被/L的

搞糊涂了

正确的语法是（，）do…/L%%i的

@echo off
setlocal enabledelayedexpansion
set Base_list[0]=Base1
set Base_list[1]=Base2
set Base_list[2]=Base3
set Base_list[3]=Base4
set Base_list[4]=Base5
set Base_list[5]=Base6
set Current_Node=Node1

REM list array:
set base_list[

REM list values only:
for /f "tokens=2 delims==" %%i in ('set Base_list[') do echo %%i

REM get size of the array:
for /f %%i in ('set base_list[ ^|find /c "="') do set count=%%i
echo size is %count%
REM subtract one because array starts with 0:
set /a count-=1

if "%Current_Node%" == "Node1" for /l %%a in (0,1,%count%) do (
  echo  %%a: some stuff with !base_list[%%a]!
)

打印：

（如果索引大于9，并且没有名称以
base\u list[
-您不指定）开头的不需要的变量，则假定您不希望保留数字序列

迭代：

for /f "tokens=1*delims==" %%a in ('set base_list[ 2^>nul') do echo %%b

或

取决于您想要执行的操作-与“打印”相同的条件。
您的代码中有几个小错误：

@echo off
setlocal enabledelayedexpansion
set Base_list[0]=Base1
set Base_list[1]=Base2
set Base_list[2]=Base3
set Base_list[3]=Base4
set Base_list[4]=Base5
set Base_list[5]=Base6
set Current_Node=Node1

rem Explicitly set the counter:
set counter=5

if "%Current_Node%" == "Node1" (
   for /l %%a in (0 , 1, %counter%) do (
   rem do some stuff
   echo Element %%a in Base_list array is: !Base_list[%%a]!
   )
)


您尚未初始化计数器变量
FOR命令的格式略有不同
注释是通过REM命令插入的，而不是//

这是您的代码的正确版本：

@echo off
setlocal enabledelayedexpansion
set Base_list[0]=Base1
set Base_list[1]=Base2
set Base_list[2]=Base3
set Base_list[3]=Base4
set Base_list[4]=Base5
set Base_list[5]=Base6
set Current_Node=Node1

rem Explicitly set the counter:
set counter=5

if "%Current_Node%" == "Node1" (
   for /l %%a in (0 , 1, %counter%) do (
   rem do some stuff
   echo Element %%a in Base_list array is: !Base_list[%%a]!
   )
)

但是，此代码可以用更简单的方式编写：

@echo off
setlocal enabledelayedexpansion

rem Create the array via elements placed in a FOR command
rem at same time, generate the counter:
set counter=0
for %%a in (Base1 Base2 Base3 Base4 Base5 Base6) do (
   set Base_list[!counter!]=%%a
   set /A counter+=1
)

rem Adjust the counter because the array is zero-based:
set /A counter-=1

set Current_Node=Node1

if "%Current_Node%" == "Node1" (
   for /l %%a in (0 , 1, %counter%) do (
   rem do some stuff
   echo Element %%a in Base_list array is: !Base_list[%%a]!
   )
)

我建议您阅读批处理文件中的阵列管理

@echo off
setlocal enabledelayedexpansion

rem Create the array via elements placed in a FOR command
rem at same time, generate the counter:
set counter=0
for %%a in (Base1 Base2 Base3 Base4 Base5 Base6) do (
   set Base_list[!counter!]=%%a
   set /A counter+=1
)

rem Adjust the counter because the array is zero-based:
set /A counter-=1

set Current_Node=Node1

if "%Current_Node%" == "Node1" (
   for /l %%a in (0 , 1, %counter%) do (
   rem do some stuff
   echo Element %%a in Base_list array is: !Base_list[%%a]!
   )
)
