使用Aspose.Cells在Excel中读取嵌入的PDF文件

Question

I'm trying to read PDF files in Excel and save it to local using Aspose.Cells for C# , but when I read the PDF's ObjectSourceFullName , it's "*. bin", and other attributes also not show anything identify it's PDF. How this happened and how to solve this? Please help me, Thanks!!!

Answer 1

You can identify the type of OLE object with its ClassIdentifier property. It is a 16-bytes number. Convert it to GUID and then check what this GUID means inside the Windows Registry.

Guid guid = new Guid(wb.Worksheets[0].OleObjects[0].ClassIdentifier);

The following screenshot explains that {b801ca65-a1fc-11d0-85ad-444553540000} actually means Adobe Acrobat Document .
