【问题描述】：

Function RemoveDataFromFile ([string] $FileType,[string] $RecordToRemove)

$stupidShit=$RecordToRemove
Write-Host $stupidShit
$RemovedLines = @()
Write-Host "Entering Remove File Proc"
$FolderName="C:\Temp\GTR"
$typeToCheck = switch ($FileType) 
    "PDT" "pdtcode" ; break
    "DET" "detnumber"; break
    "ADR" "detnumber"; break
    "POS" "detnumber"; break
    "PYD" "detnumber"; break
    "SMN" "detnumber"; break
    "REL" "pdtcode"; break
    "DED" "detnumber"; break
    "ALW" "detnumber"; break
    "TER" "detnumber"; break
    "RTN" "rtnparam01"; break

   default "Something else happened"; break
   


 $FileList = Get-ChildItem -Path $FolderName -Filter "*$FileType*"
#write-host $FileType "_" $FileList "++" $recCheck

foreach($singleFiles in $FileList)

Write-Host "Checking -" $singleFiles.Name "++ " $recCheck
    $data = foreach($line in Get-Content $singleFiles.FullName)
            
           
            Write-Host "checiking"
           
            $recCheck="$typeToCheck=""$RecordToRemove"""
            Write-Host "Record Trying to check " $RecordToRemove
              Write-Host "Entering COntent to Check - " $recCheck
           Write-Host $line
           $what=($line -match $recCheck )
           Write-Host "out before loop"  $what
        
                if( $what )
                
                Write-Host "Match Found"
                $object = New-Object -TypeName PSObject
                $object | Add-Member -Name 'Type' -MemberType NoteProperty -Value $FileType
                $object | Add-Member -Name 'FileName' -MemberType NoteProperty -Value $singleFiles.Name
                $object | Add-Member -Name 'Info' -MemberType NoteProperty -Value $line

                $RemovedLines+=$object
                
                else
                
                  $line
                
              

            
  #  $data | Set-Content $singleFiles.FullName 


return $RemovedLines



# call
$Det_RemovedLines=RemoveDataFromFile "DET" $DetRecord.EmployeeID.Trim() 

($line -match $recCheck ) is false - but is correct!!!

($line -match $recCheck ) 为假 但我在一行中检查 detnumber="303353y" cbr="detadd",detnumber="303355y",dettitle="Mrs",detsurname="Awesome123",detdatejnd= 所以条件应该返回 true 但不是。 任何帮助将不胜感激。

【问题讨论】：

截图清楚地显示了为什么不匹配——$RecordToRemove的值是303353y，但是$line的值包含303355y——倒数第二个字符是5，而不是 3

【参考方案1】：

~我没有足够的声誉，无法发表评论

我的 PowerShell 有点生锈了，会不会是 $line 或 $recCheck 有隐藏的小数？

另外，它们是相同的数据类型吗？也许尝试将它们都转换为字符串，看看会发生什么？

如果它返回为假，那么其中一定有某种东西使它们！=

编辑： 忘记这一点，它们不一样： 查看提供的屏幕截图 - 似乎 $rcCheck == "303353y" $line == "303355y"

天哪！我不敢相信我错过了——真是个愚蠢的错误。谢谢@anton。

别担心，最简单的错误有时最难发现
