Replace first character in string

I have a CSV file where I want to replace the first character that is 0 with +46 but I can't make this work as I want to.

I have the following code that works, but it works on all zeroes and not only the first one:

$csv = Import-Csv test.csv
$csv | ForEach-Object {
    $_.mobile = $_.mobile.Replace("0", "+46")
}
$csv | Export-Csv -Encoding "UTF8" new-test.csv -NoTypeInformation

Any idea how to make this work only on the first character in the string?

This happens as String.Replace() will replace all the occurrences.

In order to only replace the first one, use regular expressions. By using the beginning of line anchor, ^, the replacement is limited to start of string. Like so,

$_.mobile = $_.mobile -replace "^0", "+46"
