Question

我想创建一些函数名称数组，然后根据传递给我的脚本的参数调用它们。这可能吗？在下面的粗略示例中，如果我将2作为参数传递给脚本，我希望将$twoFuncs函数列表按顺序调用。

param ($whichFuncs)
Function a{ Write-Host "Executing function a" }
Function b{ Write-Host "Executing function b" }
Function c {Write-Host "Executing function c" }
$twoFuncs = @("a","b")
$threeFuncs = @("c","b","a")

if($whichFuncs -eq 2)
{
    # execute functions a + b
}

Answer 1

您正在寻找的是调用运算符&和foreach循环。

PS C:\Users\Frode> $twoFuncs | ForEach-Object { & $_ }
Executing function a
Executing function b

Answer 2

如何使用开关？

param ($whichFuncs)
Function a{ Write-Host "Executing function a" }
Function b{ Write-Host "Executing function b" }
Function c {Write-Host "Executing function c" }
switch ($whichFuncs)
 {
   2 {a;b}
   3 {c;b;a}
 }

在数组中按顺序调用一组函数
