 |
|
I created the following code to merge two pdfs into a single document. It works most of the time. However, one pdf throws an error when trying to retrieve the pagecount(bolded below). The error message says:key must be of type System.String.
| Code: | /// <summary>
/// Merges two pdf into single document
/// </summary>
/// <param name="file"></param>
/// <param name="title"></param>
private void Merge(MemoryStream file, string title)
{
// Open the document to import pages from it.
PdfDocument inputDocument = PdfReader.Open(file, PdfDocumentOpenMode.Import);
// Iterate pages- Next line causes problems
[b]int count = inputDocument.PageCount;[/b]
for (int idx = 0; idx < count; idx++)
{
PdfPage page = inputDocument.Pages[idx];
sourceDcoument.AddPage(page);
if (idx == 0 && title.Length > 0)
{
pageBookmarks.Add(title);
}
else
{
pageBookmarks.Add(string.Empty);
}
}
} |

Just to add on to the above message. I noticed this when I was debugging, I am not sure if this is related at all.
Object reference not set to an instance of an object.
at PdfSharp.Pdf.PdfDictionary.DictionaryElements.CreateDictionary(Type type, PdfDictionary oldDictionary)
at PdfSharp.Pdf.PdfDictionary.DictionaryElements.GetValue(String key, VCF options)
at PdfSharp.Pdf.Advanced.PdfCatalog.get_Outlines()
at PdfSharp.Pdf.PdfDocument.get_Outlines()
Any help? |

Which version of PDFsharp do you use?
If this problem also occurs with the current PDFsharp 1.2 then please provide us the PDF file that causes this error.
