Using custom type converters with C# and YamlDotNet, part 2

c# convert yaml type 0 Comments Downloads

Recently I discussed using type converters to perform custom serialization of types in YamlDotNet. In this post I'll concentrate on expanding the type converter to support deserialization as well.

I'll be reusing a lot of code and knowledge from the first part of this mini-series, so if you haven't read that yet it is a good place to start.

Using custom type converters with C# and YamlDotNet, part 1

c# convert yaml type 0 Comments Downloads

One of our internal tools eschews XML or JSON configuration files in favour of something more human readable - YAML using YamlDotNet. For the most part the serialisation and deserialisation of YAML documents in .NET objects is as straight forward as using libraries such as JSON.net but when I was working on some basic serialisation there were a few issues.

For this demonstration project, I'm going to use a pair of basic classes.

Displaying the contents of a PDF file in an ASP.NET application using GhostScript

After receiving quite a few requests on making the PDF image conversion work in a web application, I wanted to see how hard it would be to do. Not hard at all as it turns out, I had a nice working sample running with a bare 5 minutes of work.

The sample available for download below is a basic ASP.NET application, comprised of a single page with an IHttpHandler for displaying the image. In order to make this sample as easy as possible, it uses pure server side controls and code, nothing client side.

Convert a PDF into a series of images using C# and GhostScript

c# image pdf ghostscript convert gsapi_new_instance gsapi_exit gsapi_delete_instance 68 Comments Downloads

An application I was recently working on received PDF files from a webservice which it then needed to store in a database. I wanted the ability to display previews of these documents within the application. While there are a number of solutions for creating PDF files from C#, options for viewing a PDF within your application is much more limited, unless you purchase expensive commercial products, or use COM interop to embed Acrobat Reader into your application.

This article describes an alternate solution, in which the pages in a PDF are converted into images using GhostScript, from where you can then display them in your application.
