File is saving on my folder.
How i can do it. with asp.net with c#.
public static string AlldocToPDF(AlldocToPDFInput objAlldocToPDFInput, string DirvePath)
{
Byte[] Xlsbytes;
List<iTextSharp.text.Document> objDocs = new List<iTextSharp.text.Document>();
List<string> fNames = new List<string>();
try
{
foreach (var x in objAlldocToPDFInput.Documents)
{
string Filepathname = DirvePath + DateTime.Now.ToString("yyyyMMddHHmmssfff") + ".pdf";
string str = x.FileContent.ToString();
Xlsbytes = Convert.FromBase64String(str);
if (x.FileExtension == "pdf")
{
File.WriteAllBytes(Filepathname, Xlsbytes);
}
else
{
iTextSharp.text.Image image = iTextSharp.text.Image.GetInstance(Xlsbytes);
iTextSharp.text.Rectangle pageSize = null;
pageSize = new iTextSharp.text.Rectangle(0, 0, image.Width, image.Height);
using (var ms = new MemoryStream())
{
var document = new iTextSharp.text.Document(pageSize, 0, 0, 0, 0);
iTextSharp.text.pdf.PdfWriter.GetInstance(document, ms).SetFullCompression();
document.Open();
document.Add(image);
document.Close();
objDocs.Add(document);
File.WriteAllBytes(Filepathname, ms.ToArray());
}
}
fNames.Add(Filepathname);
}
string outFile = DirvePath + DateTime.Now.ToString("yyyyMMddHHmmssfff") + ".pdf";
CombineMultiplePDFs(fNames, outFile);
Xlsbytes = File.ReadAllBytes(outFile);
fNames.Add(outFile);
string Base64string = Convert.ToBase64String(Xlsbytes);
return Base64string;
}
catch (Exception ex)
{
return "False";
}
finally
{
if (fNames.Count > 1)
{
foreach (string fname in fNames)
{
if (File.Exists(fname))
{
File.Delete(fname);
}
}
}
}
}
