I want to remove specific item in my INI file.
My INI file

[Information]
Name= Joyce
Class=Elementry
Age=10

I want to remove Age=10

I tried this code, but I just can remove the value of Age which is 10.

Param(
 [parameter(mandatory=$true)]$FilePath,
 [parameter(mandatory=$true)] $a,
 [parameter(mandatory=$true)] $b,
 [parameter(mandatory=$true)] $c
 )
 Import-Module PsIni
 $ff = Get-IniContent $FilePath
 $ff["$a"]["$b"] = "$c" 
 $ff | Out-IniFile -FilePath $FilePath -Force

My Expectation output of INI file is:

[Information]
Name=Joyce
Class=Elementry

powershell ini

  You are asking a lot of questions about ini files. Have you considered more modern approach and use JSON or XML instead?

Get-IniContent returns a (nested) ordered hashtable that represents the INI file's structure.

To remove an entry, you must therefore use the ordered hashtable's .Remove() method:

# Read the INI file into a (nested) ordered hashtable.
$iniContent = Get-IniContent file.ini

# Remove the [Information] section's 'Age' entry.
$iniContent.Information.Remove('Age')

# Save the updated INI representation back to disk.
$iniContent | Out-File -Force file.ini

You could therefore modify your script as follows:

Param(
 [parameter(mandatory=$true)] $FilePath,
 [parameter(mandatory=$true)] $Section,
 [parameter(mandatory=$true)] $EntryKey,
 $EntryValue # optional: if omitted, remove the entry
)

Import-Module PsIni

$ff = Get-IniContent $FilePath

if ($PSBoundParameters.ContainsKey('EntryValue')) 
 $ff.$Section.$EntryKey = $EntryValue
 else 
 $ff.$Section.Remove($EntryKey)


$ff | Out-IniFile -FilePath $FilePath -Force

Then call it as follows; note the omission of a 4th argument, which requests removal of the entry:

.script.ps1 file.ini Information Age
