Convertfrom-string removes leading zeros

问题

Im having a problem with the Convertfrom-String cmdlet

$value = 'something:009' 
$value | ConvertFrom-String -Delimiter ':'

Output:

P1        P2
--        --
something  9

The output i want is

P1        P2
--        --
something  009

Anyone got any ideas?

Thanks in advance.

I suggest avoiding ConvertFrom-String altogether - it performs type conversions that you cannot control when you use -Delimiter, as you've experienced, and its example-driven template-based parsing is awkward.

^{On a side note: ConvertFrom-String is not available in the cross-platform PowerShell Core edition.}

In your simple case, use ConvertFrom-Csv instead:

$value = 'something:009' 
$value | ConvertFrom-Csv -Delimiter ':' -Header P1, P2

ConvertFrom-Csv reads all values as strings, as-is (with string input; enclosing double quotes around field values are removed).

mklement0 propose the best solution. You can do it too :

Solution 1 : with a simple split (not you can split with regex too)

$value = 'something:009' 
$values=$value -split ':'

[pscustomobject]@{
Val1=$values[0]
Val2=$values[1]
}

Solution 2 : with ConvertFrom-String and a Template

$template=@"
{{Val1:Abc123}:{Val2:1}}
"@

$value = 'something:009' 
$value | ConvertFrom-String -TemplateContent $template
