如果powershell中没有执行条件

Question

我从scvmm中获取VM的数据，如名称和VMhost，并存储到变量$a中

我有VM名称ex: win10-jde，我想通过使用if语句获得win10-jde名称和vmhost的详细信息，它失败了任何帮助。

$b = "win10-jde"
$a = Get-SCVirtualMachine | Select-Object name, vmhost

if ($b -match $a){
    Write-Output "$b"
}

$a输出是：

PS C:\Users\scvmmadmin> $a

Name                                       VMHost                
----                                      ------

Answer 1

您需要通过foreach循环运行包含VM详细信息的对象。而且，我将使用-eq而不是-match，因为-match用于匹配正则表达式。下面有更多..。试着做这样的事情：

$b = "win10-jde"
$VMs = Get-SCVirtualMachine | Select-Object name, vmhost

ForEach ($VM in $VMs)
{
    $Name = $VM.Name
    $VMHost = $VM.vmhost

    if ($b -eq $Name)
    {
        Write-Output "$VM"
    }
}

现在，-match操作符。一个变量将“匹配”另一个变量，如果它等于或包含在与其进行比较的变量中。例如：“蓝色”将与“蓝鲸”相配。比较运算符-eq要求一个变量与它要比较的变量相同，以便使比较成为真。

我希望这能帮到你!

Answer 2

在这里，您尝试将字符串$b与对象$a进行比较，后者永远不会返回true。您所需要做的就是比较$b和$a.name。请像这样改变你的代码。

$b = "win10-jde"
$a = Get-SCVirtualMachine | Select-Object name, vmhost
foreach($vm in $a)
{    
    if ($b -eq $vm.name)
    {
        Write-Output "$vm"
    }
}
