我如何从 cmdlet 命令获取属性并将它们作为整数保存到变量

Question

例如，我试图从 cmdlet 获取一个值，将其保存为 int 并在 PowerShell 脚本的 if 语句或 while 语句中使用它。

$value = Get-WmiObject -Class Win32_logicaldisk -过滤器"DriveType = '2'" | Select-对象大小回声$值

 Size
 ----
1992032256 <------- I am trying to get that number so that I can use it in a if statement and compare it with another number

Answer 1

像这样：

$value = Get-WmiObject -Class Win32_logicaldisk -Filter "DriveType = '2'"
$value.size

Answer 2

Get-WmiObject -Class Win32_logicaldisk -Filter "DriveType = '2'" 语句可能 return 不止一个对象。要将 Size 属性与某个值进行比较，您需要迭代结果：

Get-WmiObject -Class Win32_logicaldisk -Filter "DriveType = '2'" | ForEach-Object {
    # for demo, output to console if the Size is greater or equal then 16 GB
    $sizeGB = [math]::Round($_.Size / 1GB)  # Size is an Int64 value in Bytes
    if ($sizeGB -ge 16) {
        Write-Host "Drive $($_.DeviceID) has a total capacity of $sizeGB GB"
    }
}
