我正在尝试在外域中查找下一个可用的计算机名称。我们的计算机使用命名格式 departmentName001

部门名称003

部门名称004

...

部门名称999

我可以找到现有的计算机帐户并添加 1，但我无法让它开始查看 001，我知道使用"{0:d3}" -f但我没有正确使用它。任何人都可以帮忙吗？

function GetComputerList($ComputerName)
{
$objSearcher = New-Object System.DirectoryServices.DirectorySearcher
$objSearcher.SearchRoot = “LDAP://dc=domain,dc=local”
$objSearcher.Filter = ("(&(objectCategory=computer)(name=$ComputerName))")
$colProplist = "name"
$objSearcher.PageSize = 1000
    foreach ($i in $colPropList){[void]$objSearcher.PropertiesToLoad.Add($i)}
$colResults = $objSearcher.FindAll()
foreach ($objResult in $colResults)
    {$objComputer = $objResult.Properties; $objComputer.name}
}


$HostName = Finance
$unit="{0:d3}" -f $_

$num = GetComputerList("$HostName*") | Foreach {[int]($_.Name)} | Sort-Object | Select-Object -Last 1 
$name = $HostName+($unit+($num+1))

试试这个，它会获取名称以“departmentName”开头的所有计算机，删除所有 az 字符，只留下数字，将数字转换为整数并对它们进行排序以找到最大的一个：

$searcher = [ADSISearcher]'(&(objectCategory=computer)(name=departmentName*))'
$searcher.PageSize = 1000
$last = $searcher.FindAll() | Foreach-Object { [int]($_.Properties.name -replace '\D').Trim() } | Sort-Object | Select-Object -Last 1
$digitLength = "$last".Length
$NewComputerName = "{0}{1:D$digitLength}" -f 'departmentName',($last+1)
$NewComputerName

编辑：

# get next available number in a range of numbers. returns 5 for 1,2,3,4,6,7,9
$number = $searcher.FindAll() | Foreach-Object { [int]($_.Properties.name -replace '\D').Trim() } | Sort-Object    

for($i=0; $i -lt $number.length; $i++) {if( $number[$i+1]-$number[$i] -gt 1) {$number[$i]+1; break} }

尝试这个：

$searcher = [ADSISearcher]'(&(objectCategory=computer)(name=Finance*))'
$searcher.PageSize = 1000
$last = $searcher.FindAll() | Foreach-Object {
[string]($_.Properties.name -replace '\D')  }  | Sort-Object     
$i = 0
$last | % { if ($i -ne [int]$_ ) { $new = $i.tostring().padleft(3,'0'); break } 
else 
{ $i++ }}

$newComputerName = "finance" + $new

根据这篇文章中的信息，我对我的环境的代码进行了一些更改和调整，以检查的不仅仅是 AD .. 并且还修复了它在范围开始时不填充空白.. 我在这里写了博客:自动生成服务器名称

代码的副本也在这里，我知道它可以重构很多！
