Powershell INI editing

Question

I want to changing some values in an INI file. Unfortunately, I have keys in 2 different sections which share an identical name but need different values. My code uses the Get-IniContent function from PsIni.

Example INI file:

[PosScreen]
BitmapFile=C:\Temp\Random.bmp
Bitmap=1

[ControlScreen]
BitmapFile=C:\Temp\Random.bmp
Bitmap=1 

I need to change the above to the following:

[PosScreen]
BitmapFile=C:\Temp\FileC.bmp
Bitmap=1

[ControlScreen]
BitmapFile=C:\Temp\FileD.bmp
Bitmap=1 

The PowerShell code I am using seems to work, but it changes every value to "File D". It is obviously parsing everything twice, and the name is the same for each section.

$NewFileC = "C:\Temp\FileC.bmp"
$NewFileD = "C:\Temp\FileD.bmp"
$POSIniContent = Get-IniContent "C:\scripts\Update-EnablerImage\WINSUITE.INI"
$BOIniContent = Get-IniContent "C:\scripts\Update-EnablerImage\WINSUITE.INI"

If ($POSIniContent["PosScreen"]["BitmapFile"] -ne $NewFileC) {
  Get-Content "C:\scripts\Update-EnablerImage\WINSUITE.INI" |
    ForEach-Object {$_ -replace "BitmapFile=.+" , "BitmapFile=$NewFileC" } |
    Set-Content "C:\scripts\Update-EnablerImage\WINSUITE.INI"
}

If ($BOIniContent["ControlScreen"]["BitmapFile"] -ne $NewFileD) {
  Get-Content "C:\scripts\Update-EnablerImage\WINSUITE.INI" |
    ForEach-Object {$_ -replace "BitmapFile=.+" , "BitmapFile=$NewFileD" } |
    Set-Content "C:\scripts\Update-EnablerImage\WINSUITE.INI"
}

My struggle is how to change each one independently. I'm a bit of a scripting newbie, so calling out for some help. Tried using Conditional Logic (ForEach $line in $INIFile, for example), but no luck with that.

You are overcomplicating things. You can use Get-IniContent and Out-IniFile as follows:

$ini = Get-IniContent c:\temp\ini.ini 
$ini["posscreen"]["BitmapFile"] = "C:\Temp\FileC.bmp"  
$ini | Out-IniFile -FilePath c:\temp\ini2.ini

Note that if you want to overwrite the original file, you must add -Force to the Out-IniFile call.
