I get this error in PdfSharp.pdf folder- PdfPages.cs- ImportExternalPage when I try to use the sample code for SplitDocument:

A PDF document must be opened with PdfDocumentOpenMode.Import to import pages from it.

I'm really not sure what I am doing wrong, since the code seems very straight forward. Here is the code I use that gets the error:

filename = "test.PDF";
File.Copy(Path.Combine(@"C:\PDFs\", filename),
Path.Combine(Directory.GetCurrentDirectory(), filename), true);

// Open the file
PdfDocument inputDocument = PdfReader.Open(filename, PdfDocumentOpenMode.ReadOnly);

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;

// Add the page and save it
outputDocument.AddPage(inputDocument.Pages[idx]);
outputDocument.Save(String.Format("{0} - Page {1}.pdf", name, idx + 1));
}

Thanks in advance for any help.

If you replace PdfDocumentOpenMode.ReadOnly by PdfDocumentOpenMode.Import (as the error message says) your code will work.

Stefan ,

How to do it? I found PdfDocumentOpenMode is a property in PdfDocument, but it's internal.

Thanks
James

It's a parameter of

PdfReader.Open returns the opened PdfDocument.

This my code:
pulic void MyMethod(PdfPage pdfPage)
{
PdfDocument pdfDocument = new PdfDocument();
pdfDocument.Pages.Add(pdfPage);
GS ghostscript = new GS();
System.Drawing.Image image = ghostscript.PdfToPng(pdfDocument, 1, 96);
Stream stream = new MemoryStream();
image.Save(stream, System.Drawing.Imaging.ImageFormat.Png);
...
}
I try to use Reader.Open(), but it need pass in some parameters, I don't know what it stand for.

Please help me, thanks
James

Where is that PdfPage pdfPage coming from?
Dat's de place where you have to use PdfReader.Open().

Read this thread here carefully:
viewtopic.php?p=105#p105

Look at the first post and at the answer in the second post.
Look for PdfReader.Open ...

PdfPage pdfPage is come from base class in another assembly which I have no source code, I just try to override the abstract method.

I don't know if base class use Reader.Open() or not

That other assembly must be changed - or replaced.
No source code? Try .NET Reflector ...

PdfReader.Open(...) returns the PdfDocument.
You must specify at open that you want to open the document for import.
