Question

我有一些powershell代码，可以通过SQL查询将计算机的负载返回到数组。

查询返回的成员总数有所不同。我也对数组进行了混洗。

我想获取该数组并将其按百分比分成四个或五个较小的数组。我想预先定义百分比。例如，我可能希望看到25％，25％，25％，25％。下次我想看到10％，30％，30％，40％或另外5％，35％，30％，30％。

$phasepercents = 0.1,0.2,0.2,0.25,0.25 #Percentage of machines in each 
group

# AD groups to be created, Group5 is not needed as all EUC machines will be 
# added in the final round
$Phase0group = @()
$Phase1group = @()
$Phase2group = @()
$Phase3group = @()
$Phase4group = @()
$computers = my sql query with returned computers

$totalmachines = $computers.count #Total No of machine in the collection

$Machinesineachgroup = @()
$phasestartnumbers  = @()

# work out the percentages
$counter = 0
foreach ($phasepercent in $phasepercents)
{
$value =  $phasepercent *= $totalmachines
$value =  [Math]::floor($value) 
$Machinesineachgroup += $value
#WriteToLog "[INFO]`t,Machines in Phase$counter is $value"
$counter +=1
}
WriteToLog "[INFO-S]`t Total Machines in each phases $Machinesineachgroup"

这将根据$PercentageList中的％将您的集合分成批处理大小，然后将这些批处理存储到数组数组中。您还可以修改它，以将数组存储在自定义对象的属性中，或者根据需要存储到哈希表中。 [咧嘴]

$MasterList = 1..100
$PercentageList = 10, 30, 20, 40

$Index = 0
$BatchList = foreach ($PL_Item in $PercentageList)
    {
    $BatchSize = [math]::Round($MasterList.Count * $PL_Item / 100, 0)

    # the leading comma forces PoSh to NOT unroll the array
    #    instead, it is stored as whole
    ,$MasterList[$Index..($Index + $BatchSize - 1)]

    $Index = $Index + $BatchSize
    }

$BatchList[0] -join ', '
'=' * 30
$BatchList.ForEach({$_ -join ', '})

输出...

1, 2, 3, 4, 5, 6, 7, 8, 9, 10
