# Quick and Easy Way o convert ASP.NET Web Page to PDF

ASP.NET is an open-source server-side web application framework designed for web development to produce dynamic web pages developed by Microsoft to allow programmers to build dynamic web sites, applications and services.

iTextSharp (now iText) is a library for creating and manipulating PDF files in Java and .NET. iText was written by Bruno Lowagie. The source code was initially distributed as open source under the Mozilla Public License.

In this post, I will show how to convert web page to pdf using

16. Hi Kumar
From your error message it is clear that the asp.net user does not have access write to c drive.
Do one thing create a temp folder in c drive and write the newly created pdf to that folder.

string strFileName = @"C:\temp\test.pdf"

Could you plese suggest me what will be the variable to be used in render method.
