$file1 = GI C:\TEMP\schlecht\Settings.xml
$file2 = GI C:\TEMP\gut\Settings.xml    #路径是对的，确认了n遍
function Compare-Files{
 param(
 $file1,$file2,[switch]$IncludeEqual)
 $content1 = Get-Content $file1
 $content2 = Get-Content $file2
 $comparedLines = Compare-Object $content1 $content2 -IncludeEqual:$IncludeEqual |
 group { $_.InputObject.ReadCount } # | sort Name
 $comparedLines | foreach {
 $curr=$_ 
 switch ($_.Group[0].SideIndicator){
“==” { $right=$left = $curr.Group[0].InputObject;break}
“=>” { $right,$left = $curr.Group[0].InputObject,$curr.Group[1].InputObject;break }
“<=" { $right,$left = $curr.Group[1].InputObject,$curr.Group[0].InputObject;break }
 }
 [PSCustomObject] @{
 Line = $_.Name
 Left = $left
 Right = $right
 }
 }
 }

下图是报警
