Sorting a Dictionary on a List of Keys
I can almost hear you thinking: “What super-weird problem are you trying to solve!?” Well… it is kind of an abstract one! Imagine you have a dictionary of objects and a separate list of keys in a certain order. Now suppose you want an ordered dictionary based on the list of keys.
Dependency injection (with IOptions) in Console Apps in .NET Core
When you are used to building web applications, you kind of get hooked to the ease of Dependency Injection (DI) and the way settings can be specified in a JSON file and accessed through DI (IOptions
Part 2: Calculations with Roman Numerals using C#
In a previous article I wrote how to parse Roman Numerals in C#. This article will focus on how to calculate with the class in an intuitive way. It will show how to implement implicit casting and the add and subtraction operator overloads. Fun stuff that’s probably useful in other projects.
Part 1: Parsing Roman Numerals using C#
Lately I’ve become fascinated with the Latin language. I’m working on a project that converts photographs of Latin inscriptions on medieval statues into translated text. One of the challenges is parsing years, usually expressed in the form of Roman Numerals.
After building a parser class I noticed that it had a lot of nice characteristics: parsing, operator overloading, implicit conversions. A nice way to play around with C#.
Offline Google Authentication for MVC.Net
A while back I wanted to create an ASP.Net MVC client for Google Fit that charted my weight. It turned out that offline Google authentication wasn’t as straight forward as one would hope. This article will explain how it works using Google Fit as an example. The code is applicable to the whole Google API. In this example only one authorization is stored and used across multiple accounts.
Getting your weight from Google Fit with C#
I think Google Fit is a wonderful platform. It connects multiple devices and apps to give you insight into your fitness. I connected a Withing Smart Body Analyzer scale to the system. What I’m missing is a simple min / max weight per day graph. This blog describes how to get the weight data out of Google Fit into your C# application. You can use your own chart solution to plot a graph.
Get keywords for images from the Google Cloud Vision API with C#
This blog will explain how to use C# (.Net) and Nuget to get keywords from the Google Cloud Vision API project. I will show you how to upload your images through the API and getting the keywords using the LABEL_DETECTION feature.
Rasterizing EMF files with .Net / C#
I can almost hear you think: “Why on earth would anyone use EMF?” Well… I don’t… but MS Office does! Thumbnails that are saved in MS Word documents are in the EMF format. As I struggled to do something with one, I realized that I had to convert it first to a more “easy to handle” format: PNG. Easier said than done.
A BlockHasher helper class
There are a few instances in which you’ll need to hash a combination of data. You might resort to creating one big string and hashing that. It has a clear disadvantage from a memory and processing point of few. It might even be impractical when files or streams are involved. That’s why I created a BlockHasher utility class that helps to generate these types of hashes.
An evaluator for simple script evaluation
In a previous blog I explored how to create a dynamic compiler. In this blog I’ll explore how to create an evaluator that aids in the compilation of classes. It will take care of the ceremony needed to wrap the code into a class, compile it and retrieve the result.
