How do I walk through tree of Pdf Objects in PDFSharp?

由 元气小坏坏 提交于 2019-12-05 04:28:59

The root node is document.Internals.Catalog. And I want to to walk down through all the document.Internals.Catalog.Elements until I have visited every element. One of the problems I run into is that there are circular references in the tree and I can't figure out how to detect them. Any code samples out

How to create PDF in ASP.NET

问题 I have seen lot of threads on it and really no good answer anywhere. Or rather none suit my situation. We need to print Business Letter for given list with mail merge facilities. Client is not willing to spend $$ On paid ASP.NET control to make PDF. so I opt for WKHTMLtoPDF and it works fine for us until one day client try to get PDF of 100+ leads, resulting in complete failure of PDF generation. It works just fine with 10-20 page PDF, but not for 100. Is there any Tips & Trick to improve
