powershell - 使用if条件在PowerShell中进行比较

Question

我试图从系统中获取.Net版本，并尝试检查我的系统是否具有.NET版本大于或等于4.6。下面是代码。从代码中，我可以检索发行版本。我在if条件下面临问题。

$myArray = @()

$myArray = @(Get-ChildItem 'HKLM:\SOFTWARE\Microsoft\NET Framework Setup\NDP' -Recurse |
    Get-ItemProperty -Name Release,Release -EA 0 |
    Where { $_.PSChildName -match '^(?!S)\p{L}' } |
    Select Release)
Write-Output $myArray[0]
Write-Output $myArray[1]

$var1 = 393295
foreach ($var in $myArray) {
    Write-Output $var
    if ($var -ge $var1) {
        Write-Output same
    } else {
        Write-Output NOT same
    }
}

我收到此错误:

Cannot compare "@{Release=461808}" to "393295" because the objects are not the
same type or the object "@{Release=461808}" does not implement "IComparable".

将foreach行更改为

foreach($var in $myArray.Release)
