集合中包含的變量

Question

IF命令有一種方法將變量包含在一組值中？

我的意思是：

IF %% i的（ABC 123 OPL）回聲首先設置

IF %% i的（XYZ 456 BNM）回聲第二設定

Answer 1

：

C:\Users\preet>set val=99 
C:\Users\preet>for %f in (100 99 21) do @if (%f)==(%val%) echo found it %f 
found it 99 

在一個批處理文件

set val=99 
for %%f in (100 99 21) do @if (%%f)==(%val%) echo found it %%f 

Answer 2

您可以使用for聲明來做到這一點。這裏有一個腳本，它可以讓你喜歡的東西運行：

myprog 456 

，它會輸出in set 2：在命令行

@setlocal enableextensions enabledelayedexpansion 
@echo off 
for %%a in (abc 123 opl) do (
    if "x%%a"=="x%1" echo in set 1 
) 
for %%a in (xyz 456 bnm) do (
    if "x%%a"=="x%1" echo in set 2 
) 
@endlocal

而且您也不僅限於在Windows計算機中進行批處理。還有vbscript（和powershell）。這裏是你如何檢查使用VBScript

strVar = WScript.Arguments(0) 
Set dictfirst = CreateObject("Scripting.Dictionary") 
Set dictsecond = CreateObject("Scripting.Dictionary") 
dictfirst.Add "abc",1 
dictfirst.Add "123",1 
dictfirst.Add "opl",1 
dictsecond.Add "xyz",1 
dictsecond.Add "456",1 
dictsecond.Add "bnm",1 
If dictfirst.Exists(strVar) Then 
    WScript.Echo strVar & " exists in first set" 
ElseIf dictsecond.Exists(strVar) Then 
    WScript.Echo strVar & " exists in second set" 
Else 
    WScript.Echo strVar & " doesn't exists in either sets" 
End If 

用法：

C:\test>cscript //nologo test.vbs abc 
abc exists in first set 

C:\test>cscript //nologo test.vbs xyz 
xyz exists in second set 

C:\test>cscript //nologo test.vbs peter 
peter doesn't exists in either sets
