Convert Linq Code To Dotnet 2.0?

string pdfpath = Server.MapPath("images");
string imagepath = Server.MapPath("Images");
using (Stream inputPdfStream = new FileStream(pdfpath + "\NLI_Filled_out.pdf", FileMode.Open, FileAccess.Read, FileShare.Read))
using (Stream inputImageStream = new FileStream(imagepath + "\sign2.gif", FileMode.Open, FileAccess.Read, FileShare.Read))
using (Stream outputPdfStream = new FileStream(pdfpath + "\NLI_Filled_output.pdf", FileMode.Create, FileAccess.Write, FileShare.None))
{
var reader = new PdfReader(inputPdfStream);
var stamper = new PdfStamper(reader, outputPdfStream);
var pdfContentByte = stamper.GetOverContent(3);
iTextSharp.text.Image image = iTextSharp.text.Image.GetInstance(inputImageStream);
image.ScalePercent(24f);
image.SetAbsolutePosition(100, 130);
pdfContentByte.AddImage(image);
stamper.Close();
}

I have the above code in 3.5 using linq..i want to convert it into dotnet 2.0..
