Question

我从scvmm获取VM的数据，如名称和VMhost，并存储到变量$ a

我有VM名称ex：win10-jde我想通过使用if语句获取win10-jde名称和vmhost详细信息它没有任何帮助

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

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

$a输出为：

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，我会使用-eq而不是-match，因为-match用于匹配正则表达式。更多关于以下内容...尝试这样的事情：

$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运算符。一个变量将匹配＆＃34;另一个变量，如果它等于或包含在所比较的变量中。例如。＆＃34;蓝色＆＃34;将匹配＆＃34;蓝鲸＆＃34;。比较运算符-eq要求一个变量与要比较的变量相同，以便比较为真。

我希望这有帮助！

Answer 2

在这里，您尝试将字符串$b与对象$a进行比较，该对象永远不会返回true。您只需将$b与$a.name进行比较即可。请更改您的代码。

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

如果条件没有在powershell中执行
