* Sample of a PowerShell script
[void][Reflection.Assembly]::LoadFile("C:\System\Lib\PdfSharp.dll")
$doc = [PdfSharp.Pdf.IO.PdfReader]::Open("C:\Test\PDF\SampleField.pdf", [PdfSharp.Pdf.IO.PdfDocumentOpenMode]::Modify)
$form = $doc.AcroForm
if($form.Elements.ContainsKey("/NeedAppearances") -eq $true){
$form.Elements["/NeedAppearances"] = [PdfSharp.Pdf.PdfBoolean]::True
}else{
$form.Elements.Add("/NeedAppearances", [PdfSharp.Pdf.PdfBoolean]::True)

$fields = $form.Fields

$fields["Age"].Value = [PdfSharp.Pdf.PdfString]::new("25")
$fields["Mail"].Value = [PdfSharp.Pdf.PdfString]::new("foo@***.com")
