Use abcpdf in C # To process PDF, so easy

• Abcpdf Overview
• Usage

In the past few days, the project needs to guide the page into PDF. At the beginning, itextsharp was used. I thought it was complicated to process pages. Later, I accidentally saw abcpdf, which is very simple to use, you can record some common operations and share them with everyone. If you don't talk nonsense, paste the Code directly.

Modification, is there a link to the official website with more code? Why ???

Abcpdf Overview

Http://www.websupergoo.com/

The demo uses the latest version abcpdf. Net 9.1x64. It supports the latest Win8, ie10 (server version), server2003, XP, Vista, win7, and Win8 versions.

Abcpdf has a 30-day trial

Reference Method, install abcpdf component, there are two DLL is useful, need to add reference to abcpdf. dll, ABCpdf9-64.dll (engine components) in the bin directory can be

It has other components, such as functions not available in itextsharp. If you can directly specify a URL, you can convert the page to PDF. This is also its strength.

When selecting a version, you must note that the 64-bit and 32-bit versions are differentiated. if the version is wrong, an error will occur. You must note that this issue may occur during IIS deployment, please refer to the official information: http://www.websupergoo.com/support.htm FAQ introduction more detailed

Usage

Let's take a look at the code below.

Add reference:

Using websupergoo. abc00009;

String url = "http://www.websupergoo.com/support.htm"; private void downloadpdf (string filename, byte [] buffer) {response. buffer = false; response. addheader ("connection", "keep-alive"); response. contenttype = "application/octet-stream"; response. addheader ("content-disposition", "attachment; filename =" + filename); response. addheader ("Content-Length", buffer. length. tostring (); response. binarywrite (Buffer);} private string getfilename () {return datetime. now. tostring ("yyyy-mm-dd-hh-mm-SS") + ".

The above are some of the features I have used, and some of them are also very useful.

DOC also supports addimagehtml

Parameter description:

HTML: HTML to be added

Paged: whether to pagination; true: Enable pagination

Width: The page width (the width of the browser when the browser parses HTML)

Disablecache: whether to ignore the cache; true: Disable caching; false: enable caching

One thing to mention is the technical support. The official website is doing well. A support page covers many common problems and solutions, which is fairly detailed. I wish you a pleasant use.
