Save Pdf in Zip with MemoryStream - c#

I try the save multiples files pdf in zip but I can't, can somebody can help me?
using (MemoryStream memorystream = new MemoryStream())
{
string zip = #"C:\Temp\ZipFile.zip";
using (var archive = new ZipArchive(memorystream, ZipArchiveMode.Create, true))
{
for (int i = 0; i < 1; i++)
{
ZipArchiveEntry file = archive.CreateEntry(string.Format("Test{0}.pdf", i), CompressionLevel.Optimal);
using (Stream stream = file.Open())
{
Document document = new Document(PageSize.A4, 25, 25, 30, 30);
PdfWriter writer = PdfWriter.GetInstance(document, memorystream);
document.Open();
//
PdfPTable table = new PdfPTable(7);
Font fdefault = FontFactory.GetFont("Arial", 9, Font.NORMAL, BaseColor.DARK_GRAY);
table.AddCell(new Paragraph("Container", fdefault));
table.AddCell(new Paragraph("Code", fdefault));
table.AddCell(new Paragraph("ITEM", fdefault));
table.AddCell(new Paragraph("Reference", fdefault));
table.AddCell(new Paragraph("Description", fdefault));
table.AddCell(new Paragraph("Size", fdefault));
table.AddCell(new Paragraph("Quantity", fdefault));
document.Add(table);
document.Close();
writer.Close();
memorystream.Close();
}
}
}
using (var fileStream = new FileStream(zip, FileMode.Create))
{
memorystream.Seek(0, SeekOrigin.Begin);
memorystream.CopyTo(fileStream);
}
}
I do it that with ExcelPackage and work but this don't work, I don't know the problem. I would appreciate if anyone can help me with this problem.


You've got two fatal flaws.
First, you are binding the PdfWriter to the zip's MemoryStream instead of the Stream that you are getting back from ZipArchiveEntry.Open(). So change this line:
PdfWriter writer = PdfWriter.GetInstance(document, memorystream);
To this:
PdfWriter writer = PdfWriter.GetInstance(document, stream);
Second but related to the first, you are closing the zip's MemoryStream inside of the for loop. Just kill off the line:
memorystream.Close();
Putting that all together and switching over to the preferred using pattern you get this:
using (var zipMemorystream = new MemoryStream())
{
using (var archive = new ZipArchive(zipMemorystream, ZipArchiveMode.Create, true))
{
for (int i = 0; i < 10; i++)
{
var file = archive.CreateEntry(string.Format("Test{0}.pdf", i), CompressionLevel.Optimal);
using (Stream stream = file.Open( ))
{
using( var document = new Document(PageSize.A4, 25, 25, 30, 30) )
{
using( var writer = PdfWriter.GetInstance(document, stream))
{
document.Open();
//
var table = new PdfPTable(7);
var fdefault = FontFactory.GetFont("Arial", 9, iTextSharp.text.Font.NORMAL, BaseColor.DARK_GRAY);
table.AddCell(new Paragraph("Container", fdefault));
table.AddCell(new Paragraph("Code", fdefault));
table.AddCell(new Paragraph("ITEM", fdefault));
table.AddCell(new Paragraph("Reference", fdefault));
table.AddCell(new Paragraph("Description", fdefault));
table.AddCell(new Paragraph("Size", fdefault));
table.AddCell(new Paragraph("Quantity", fdefault));
document.Add(table);
document.Close();
}
}
}
}
}
string zip = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Desktop), "ZipFile.zip");
using (var fileStream = new FileStream(zip, FileMode.Create))
{
zipMemorystream.Seek(0, SeekOrigin.Begin);
zipMemorystream.CopyTo(fileStream);
}
}

If I disable this line the PDF file is created but damaged it cannot be opened.
The error is :
Object reference not set to an instance of an object
I really hope in your help.

Transform IText7 to base64 C# [duplicate]

I am trying to get a pdf from datatable and attach it to an entity in CRM. For that purpose I use this code. Unfortunately created pdf is broken, I am unable to open it. Any ideas?
private static string ExportToBase64Pdf(DataTable dt, string entityName)
{
using (MemoryStream memoryStream = new MemoryStream())
{
Document document = new Document(PageSize.A4);
PdfWriter writer = PdfWriter.GetInstance(document, memoryStream);
document.Open();
Font font5 = FontFactory.GetFont(FontFactory.HELVETICA, 5);
PdfPTable table = new PdfPTable(dt.Columns.Count);
float[] widths = new float[dt.Columns.Count];
for (int i =0; i<dt.Columns.Count; i++) { widths[i] = 4f; }
table.SetWidths(widths);
table.WidthPercentage = 100;
PdfPCell cell = new PdfPCell(new Phrase(entityName));
cell.Colspan = dt.Columns.Count;
foreach (DataColumn c in dt.Columns)
{
table.AddCell(new Phrase(c.ColumnName, font5));
}
foreach (DataRow r in dt.Rows)
{
for (int i = 0; i < dt.Columns.Count; i++)
{
table.AddCell(new Phrase(r[i].ToString(), font5));
}
}
document.Add(table);
var bytes = memoryStream.ToArray();
var encodedPDF = Convert.ToBase64String(bytes);
document.Close();
return encodedPDF;
}
}

You retrieve the document bytes before the document is finished by closing:
var bytes = memoryStream.ToArray();
var encodedPDF = Convert.ToBase64String(bytes);
document.Close();
Move the close call before the ToArray call.

ItextSharp Columntext in my PDF

i´m working at a little program.
I have a PDF with 17 pages and i want to place columntext on some of them.
But after creating the PDF i get only Page one out.
{
string newfile = "newfile.pdf";
FileStream fs = new FileStream(newfile, FileMode.Create, FileAccess.Write);
PdfReader reader = null;
PdfWriter writer = null;
PdfImportedPage page = null;
Document dc = null;
dc = new Document(reader.GetPageSizeWithRotation(1));
writer = PdfWriter.GetInstance(dc, fs);
dc.Open();
int numberOfPages = reader.NumberOfPages;
PdfContentByte cb = writer.DirectContent;
reader = new PdfReader(pdfPath);
for (int i = 1; i <= numberOfPages; i++)
{
page = writer.GetImportedPage(reader, startPage);
cb.AddTemplate(page, 0, 0);
if (startPage == 1)
{
cb.BeginText();
ColumnText.ShowTextAligned(cb, Element.ALIGN_LEFT, new Phrase(new Chunk("<<NAME>>", FontFactory.GetFont("c:\\windows\\fonts\\Roboto-BoldCondensed.ttf", 15, BaseColor.BLACK)).SetSkew(0, 10)), 367.7F, 140.7F, 10);
cb.EndText();
}
startPage++;
}
dc.Close();
fs.Close();
writer.Close();
reader.Close();
}

I tried to use stamper but the PDF file ist damaged. Something is wrong with my code string newfile = "newfile2.pdf";

itextSharp datatable to pdf base64 string - pdf damaged

I am trying to get a pdf from datatable and attach it to an entity in CRM. For that purpose I use this code. Unfortunately created pdf is broken, I am unable to open it. Any ideas?
private static string ExportToBase64Pdf(DataTable dt, string entityName)
{
using (MemoryStream memoryStream = new MemoryStream())
{
Document document = new Document(PageSize.A4);
PdfWriter writer = PdfWriter.GetInstance(document, memoryStream);
document.Open();
Font font5 = FontFactory.GetFont(FontFactory.HELVETICA, 5);
PdfPTable table = new PdfPTable(dt.Columns.Count);
float[] widths = new float[dt.Columns.Count];
for (int i =0; i<dt.Columns.Count; i++) { widths[i] = 4f; }
table.SetWidths(widths);
table.WidthPercentage = 100;
PdfPCell cell = new PdfPCell(new Phrase(entityName));
cell.Colspan = dt.Columns.Count;
foreach (DataColumn c in dt.Columns)
{
table.AddCell(new Phrase(c.ColumnName, font5));
}
foreach (DataRow r in dt.Rows)
{
for (int i = 0; i < dt.Columns.Count; i++)
{
table.AddCell(new Phrase(r[i].ToString(), font5));
}
}
document.Add(table);
var bytes = memoryStream.ToArray();
var encodedPDF = Convert.ToBase64String(bytes);
document.Close();
return encodedPDF;
}
}

You retrieve the document bytes before the document is finished by closing:
var bytes = memoryStream.ToArray();
var encodedPDF = Convert.ToBase64String(bytes);
