Question

我有两个循环：

$computer = $args[0]

$colProcData = @()
$procs = get-process -computername $computer | sort -descending "WorkingSet" | select -first 3
foreach($proc in $procs)
{
    $machine = $proc.MachineName
    $process = [String]$proc.ProcessName
    $WorkingSet = [int64]($proc.WorkingSet64/1024)
    $id = $proc.Id
    $CPU = ($proc.CPU)

    $procdata = new-object psobject
    $procdata | add-member noteproperty machine $machine
    $procdata | add-member noteproperty process $process
    $procdata | add-member noteproperty usedRam-MB $WorkingSet 
    $procdata | add-member noteproperty id $id
    $procdata | add-member noteproperty CPU $CPU

    $colProcData += $procdata
}
$colProcData | Sort-Object usedRam-MB -descending  | Format-Table -AutoSize  | out-default



$colProcData = @()
$procs = get-process -computername $computer | sort -descending "WorkingSet" | select -last 3
foreach($proc in $procs)
{
    $machine = $proc.MachineName
    $process = [String]$proc.ProcessName
    $WorkingSet = [int64]($proc.WorkingSet64/1024)
    $id = $proc.Id
    $CPU = ($proc.CPU)

    $procdata = new-object psobject
    $procdata | add-member noteproperty machine $machine
    $procdata | add-member noteproperty process $process
    $procdata | add-member noteproperty usedRam-MB $WorkingSet
    $procdata | add-member noteproperty id $id
    $procdata | add-member noteproperty CPU $CPU

    $colProcData += $procdata
}
$colProcData | Sort-Object usedRam-MB -descending  | Format-Table -AutoSize  | out-default

唯一的区别是第一个/最后一个。当我运行“.\scriptName.ps1 systemName”时，我得到：

process    usedRam-MB   id CPU
-------    ----------   -- ---
mysqld         135812 1692
WmiPrvSE        79560 6184
powershell      51724 6644



process  usedRam-MB   id CPU
-------  ----------   -- ---
LogonUI         264  580
Idle             24    0
sqlservr   -1987392 1640

如何摆脱减去？仅供参考：systemName是远程计算机，而不是localhost！如果我在localhost上运行它我没有减去：

process  usedRam-MB   id CPU
-------  ----------   -- ---
mysqld       135888 1692
WmiPrvSE      80508 6184
svchost       50720  832



process  usedRam-MB   id CPU
-------  ----------   -- ---
sqlservr   10618744 1640
LogonUI         264  580
Idle             24    0

另有资料：

systemName上的内存总计：12.000 MB

请帮忙。

Answer 1

在分割之前，WorkingSet64的价值是什么？这会产生正数吗？

$WorkingSet = $proc.WorkingSet64/1mb

顺便说一下，当前表达式得到KB的结果（一次除以1024）

Answer 2

您可以使用.Net ABS功能：

[Math]::Abs($WorkingSet)

powerShell返回减去int？
