如何使用PowerShell变量作为命令参数? [英] How to use a PowerShell variable as command parameter?

问题描述

我正在尝试使用变量作为命令的参数，但无法完全弄清楚.假设MyCommand将接受两个参数:option1和option2，并且它们接受布尔值.如何使用 $ newVar 代替选项1或2?例如:

I'm trying to use a variable as a command's parameter but can't quite figure it out. Let's say MyCommand will accept two parameters: option1 and option2 and they accept boolean values. How would I use $newVar to substitute option 1 or 2? For example:

$newVar = "option1"
MyCommand -$newVar:$true

我一直沿用的思路.'找不到一个接受参数'-System.String option1'的位置参数..

更具体地说:
此处，CSV文件是其他策略的输出.循环遍历文件中的每个属性，并在我的策略 asdf 中设置该值；因此-$_.name:$_.value应该替换为-AllowBluetooth:true.

More Specifically:
Here, the CSV file is an output of a different policy. The loop goes through each property in the file and sets that value in my policy asdf; so -$_.name:$_.value should substitute as -AllowBluetooth:true.

Import-Csv $file | foreach-object {
    $_.psobject.properties | where-object {
    # for testing I'm limiting this to 'AllowBluetooth' option
    if($_.name -eq "AllowBluetooth"){
    Set-ActiveSyncMailboxPolicy -Identity "asdf" -$_.name:$_.value
    }}
}

推荐答案

通常情况下，要使用变量来填充cmdlet参数，您将使用哈希表变量，并使用@

Typically to use a variable to populate cmdlet parameters, you'd use a hash table variable, and splat it, using @

 $newVar = @{option1 = $true}
 mycommand @newVar

添加的示例:

$AS_policy1 = @{
Identity = "asdf"
AllowBluetooth = $true
}

Set-ActiveSyncMailboxPolicy @AS_policy1
