Below is the code for file delete:

public void ConvertImageToPdf(string ImageLocation,string SaveFilePath,string TypeDoc)
{
    Document document = new Document();
    using (var stream = new FileStream(SaveFilePath, FileMode.Create, FileAccess.Write, FileShare.None))
    {
        PdfWriter.GetInstance(document, stream);
        document.Open();
        using (var imageStream = new FileStream(ImageLocation, FileMode.Open, FileAccess.Read, FileShare.ReadWrite))
        {
            //System.Drawing.Image img = System.Drawing.Image.FromFile(ImageLocation);
             var images = iTextSharp.text.Image.GetInstance(imageStream);
            images.ScaleAbsolute(500f,300f);
            Paragraph pr = new Paragraph(TypeDoc);
            //System.Drawing.Image image = resizeImage(img, new Size(200, 200));
            //  image.Width = 300;
            document.Add(pr);
            document.Add(images);
            if (document != null)
            {
                Console.WriteLine("Succesfull");
                File.Delete(ImageLocation);
            }
        }
        document.Close();
    }
