如何在 PDFsharp 中将 stream 转换为 PdfDocument

Question

Everywhere I get examples of creating PdfDocument like this:

PdfDocument document = PdfReader.Open(fiePath, PdfDocumentOpenMode.Import);

But I don't have the path of file. I want to convert Stream to PdfDocument . I tried this:

PdfDocument document = new PdfDocument(stream);

but it always gives 0 as PageCount and PageSize .

Answer 1

PdfReader.Open can be invoked with a filename or with a stream.

What you tried ( new PdfDocument(stream) ) creates a new and empty document that can be written to the stream by invoking Save() without parameter. This creates a document, but does not open it.
