How to edit INI file value in Powershell? - powershell

Question

I have an INI file:
[Name]
Female = 10
Male = 30
[Class]
Kids = 2
Adult = 10
I want to change the value of each section. Give me idea please.
I tried this code:
function Set-OrAddIniValue
{
Param(
[string]$FilePath,
[hashtable]$keyValueList
)
$content = Get-Content $FilePath
$keyValueList.GetEnumerator() | ForEach-Object {
if ($content -match "^$($_.Key)=")
{
$content= $content -replace "^$($_.Key)=(.*)", "$($_.Key)=$($_.Value)"
}
else
{
$content += "$($_.Key)=$($_.Value)"
}
}
$content | Set-Content $FilePath
}
this is the code

Answer 1

You would do so:
$ini = Get-IniContent "<pathToYourIniFile>"
$ini["<yourSection>"]["<yourKey>"] = "<yourValue>"
$ini | out-inifile -FilePath "<pathToYourIniFile>"

Answer 2

If you updated your code to the following, it will be more successful:
function Set-OrAddIniValue
{
Param(
[string]$FilePath,
[hashtable]$keyValueList
)
$content = Get-Content $FilePath
$keyValueList.GetEnumerator() | ForEach-Object {
if ($content -match "$($_.Key)\s*=")
{
$content= $content -replace "$($_.Key)\s*=(.*)", "$($_.Key)=$($_.Value)"
}
else
{
$content += "$($_.Key)=$($_.Value)"
}
}
$content | Set-Content $FilePath
}
One problem will be if you add extra key/value pairs, they will all be added to the last section. In other words, the code is not section-aware.
