{s:navigationPrevUpNext|ProtectDocument-sample|PDFsharpSamples|TextLayout-sample}
This sample shows how to convert a PDF document with n pages into n documents with one page each.

==PDF Output File==

See the PDF files created by this sample:

First page: {s:PdfLink|SplitDocument-sample%2fPortable%20Document%20Format%20-%20Page%201_tempfile.pdf|output.pdf} (31 kB){br}
Second page: {s:PdfLink|SplitDocument-sample%2fPortable%20Document%20Format%20-%20Page%202_tempfile.pdf|output.pdf} (17 kB)

{s:note} the sample creates six pages from the sample document, only two pages are provided here.

==Screen Shots==
Here are two sample screen shots:

{s:ImageThumbLink|Screen shot of page 2|SplitDocument-sample%2fSplitDocument2th.png|SplitDocument-sample%2fSplitDocument2.png}{br}
{s:note} the sample creates six pages from the sample document, only two pages are shown here.

==Source Code==

This is the whole source code needed to create the PDF file:
{s:beginCsharp}
// Get a fresh copy of the sample PDF file
const string filename = "Portable Document Format.pdf";
File.Copy(Path.Combine("../../../../../PDFs/", filename), 
  Path.Combine(Directory.GetCurrentDirectory(), filename), true);
&nbsp;
// Open the file
PdfDocument inputDocument = PdfReader.Open(filename, PdfDocumentOpenMode.Import);
&nbsp;
string name = Path.GetFileNameWithoutExtension(filename);
for (int idx = 0; idx < inputDocument.PageCount; idx++)
{
  // Create new document
  PdfDocument outputDocument = new PdfDocument();
  outputDocument.Version = inputDocument.Version;
  outputDocument.Info.Title =
    String.Format("Page {0} of {1}", idx + 1, inputDocument.Info.Title);
  outputDocument.Info.Creator = inputDocument.Info.Creator;
&nbsp;
  // Add the page and save it
  outputDocument.AddPage(inputDocument.Pages&#0091;idx&#0093;);
  outputDocument.Save(String.Format("{0} - Page {1}_tempfile.pdf", name, idx + 1));
}
{s:endCsharp}
