powershell foreach 循环失败，因为它通过第一次测试增加计数

有人要求我监控 Windows 服务器上的 c:\temp。我需要知道有多少个文件夹，以及它们存在的时间是否超过 1、2 和 3 分钟。此报告以基本形式工作，但并不完全正确。一旦有 1 个文件夹，我仍然会收到一份报告，称它存在超过 3 分钟，这是错误的。我的 for 循环有什么问题？我想要使用 for 循环来计算存在且具有特定年龄的文件夹的数量。但是 for 循环循环一次，然后我得到计数​​器 = 1，即使这是错误的。即它是几秒前，但我收到的报告说它存在了 3 分钟。任何输入都将不胜感激。谢谢

以下是我的可能很差的代码...

    $Now = Get-Date
    $OneMinute = 1
    $TwoMinutes = 2
    $ThreeMinutes = 3
    $TargetFolder = "C:\Temp"
    $LastWrite1Min = $Now.AddMinutes(-$OneMinute)
    $LastWrite2Min = $Now.AddMinutes(-$TwoMinutes)
    $LastWrite3Min = $Now.AddMinutes(-$ThreeMinutes)
    $i=0
    $j=0
    $k=0
    $g=0
    $StringThere = "There are "
    $StringOne = "Folder(s) older than 1 Minute"
    $StringTwo = "Folder(s) Older than 2 Minute"
    $StringThree = "Folder(s) Older than 3 Minute"

    $directoryInfo = Get-ChildItem C:\Temp | Measure-Object
    #$directoryInfo.count #Returns the the number folders within the directory
    If ($directoryInfo.count -eq 0){
    write-host "Folder is empty - Good!"
    }

    ##################################################
    If ($directoryInfo.count -ne 0){
    write-host "Temp has at least one folder present - ... "

    $Folders = get-childitem -path $TargetFolder | 
    Where {$_.psIsContainer -eq $true} | 
    Where {$_.LastWriteTime -le "$LastWrite1Min"} 
        foreach ($Folder in $Folders)
        {
            $i = $i + 1 
        }

    $Folders = get-childitem -path $TargetFolder | 
    Where {$_.psIsContainer -eq $true} | 
    Where {$_.LastWriteTime -le "$LastWrite2Min"} 

        foreach ($Folder in $Folders)
        {    
            If ($Folder -ne "`0" ){
                $j = $j + 1 
            }     
        }
    $Folders = get-childitem -path $TargetFolder | 
    Where {$_.psIsContainer -eq $true}  |
    Where{ $_.LastWriteTime -le "$LastWrite3Min"} 

        foreach ($Folder in $Folders)
        {
            if($_.LastWriteTime -le "$LastWrite3Min"){
            }
        }
        foreach ($Folder in $Folders)
              {
                  if($_.LastWriteTime -le "$LastWrite3Min")
                  {   
                        $k = $k + 1      
                  }
              }    

    }#end of not zero if 
    #######################################################

    write-host $StringThere $i $StringOne
    write-host $StringThere $j $StringTwo
    write-host $StringThere $k $StringThree
    write-host $exitcode

    exit $exitcode

我需要正确的退出代码，但 for 循环却让这个代码完全错误。谢谢！

这是一个可以运行的版本，可以进一步改进。

$Now = Get-Date
$TargetFolder = "C:\Temp"
$LastWrite1Min = $Now.AddMinutes(-1)
$LastWrite2Min = $Now.AddMinutes(-2)
$LastWrite3Min = $Now.AddMinutes(-3)
$i=0
$j=0
$k=0

$StringThere = "There are "
$StringOne = "Folder(s) older than 1 Minute"
$StringTwo = "Folder(s) Older than 2 Minute"
$StringThree = "Folder(s) Older than 3 Minute"

$directoryInfo = Get-ChildItem C:\Temp | Measure-Object
#$directoryInfo.count #Returns the the number folders within the directory
If ($directoryInfo.count -eq 0){
write-host "Folder is empty - Good!"
}

##################################################
If ($directoryInfo.count -ne 0)
{
    write-host "Temp has at least one folder present - ... "

    $Folders = get-childitem -path $TargetFolder | 
    Where {$_.psIsContainer -eq $true} 

    foreach ($Folder in $Folders)
    {
        if ($Folder.LastWriteTime -le $LastWrite3Min)
        {
            $k++ 
        }
        elseif ($Folder.LastWriteTime -le $LastWrite2Min)
        {
            $j++
        }
        elseif ($Folder.LastWriteTime -le $LastWrite1Min)
        {
            $i++
        }
    }

}#end of not zero if 
#######################################################

write-host $StringThere $i $StringOne
write-host $StringThere $j $StringTwo
write-host $StringThere $k $StringThree
