How to read a specific item of INI file using PowerShell? - powershell

Question

I want to read a specific item of my INI file, I have 5 Items in the section of my INI file, and I want to read 4 items, except items number 3.
I already tried to read all the items, but I can not find a way how to specify the item that I want to read and the format of the file that I read is like this:
Name Value
AA 12
BB 13
CC 14
DD 15
EE 16
I used this command to execute it.
File1.ps1 Read-File -FilePath C:\Users\Data.ini -a_section Code -store C:\Users\
function Read-File {
Param(
[Parameter(Mandatory=$true)]$FilePath,
[Parameter(Mandatory=$true)]$a_section,
[Parameter(Mandatory=$true)]$store
)
$input_file = $FilePath
$ini_file = #{}
Get-Content $input_file | ForEach-Object {
$_.Trim()
} | Where-Object {
$_ -notmatch '^(;|$)'
} | ForEach-Object {
if ($_ -match '^\[.*\]$') {
$section = $_ -replace '\[|\]'
$ini_file[$section] = #{}
} else {
$key, $value = $_ -split '\s*=\s*', 2
$ini_file[$section][$key] = $value
}
}
$Path_Store = $store
$Get_Reg = $ini_file.($a_section)
$Output = $Get_Reg | Out-File $Path_Store\Out_Test
}
$cmd, $params = $args
& $cmd #params
My expectation result, I have an output file like this
AA=12
BB=13
DD=15
EE=16
My INI File look like this:
[Name]
1=Joe
2=Grace
[Code]
AA=12
BB=13
CC=14
DD=15
EE=16

Try this:
function Get-IniSection {
Param(
[Parameter(Mandatory=$true)]$Path,
[Parameter(Mandatory=$true)]$SectionName
)
$ini_file = #{}
Get-Content $Path | ForEach-Object {
$_.Trim()
} | Where-Object {
$_ -notmatch '^(;|$)'
} | ForEach-Object {
if ($_ -match '^\[.*\]$') {
$section = $_ -replace '\[|\]'
$ini_file += #{ $section = #{} }
} else {
$key, $value = $_ -split '\s*=\s*', 2
$ini_file[$section] += #{ $key = $value }
}
}
return $ini_file[$SectionName]
}
$section = Get-IniSection -Path "C:\temp\test.ini" -SectionName "code"
$section.GetEnumerator() | Where-Object { $_.Name -ne "EE" }
$section.GetEnumerator() | ForEach-Object { "$($_.Name)=$($_.Value)" }
$section.GetEnumerator() |
Where-Object { $_.Name -in #("A1","AE","AP","AS","E1","E2","JP","M1","M2","N1","N2","P1","P2","P3","P4","PR","RU","S1","S2","W1","W2","W3","W4","ZH") } |
Select-Object -ExpandProperty "Value"
$section.GetEnumerator() |
Where-Object { $_.Name -in #("A1","AE","AP","AS","E1","E2","JP","M1","M2","N1","N2","P1","P2","P3","P4","PR","RU","S1","S2","W1","W2","W3","W4","ZH") } |
Foreach-Object { ($_.Value -split ",")[0] }
