The builder pattern is a design pattern that helps us create complex objects. Let's dive into the builder design pattern, one of many awesome design patterns!
Have you ever wanted to change a picture into ASCII art? Now you can with your very own C# program that can generate ASCII art! Sample code included!
The facade pattern is useful for hiding complexity by moving dependencies behind an API. Let's dive into the facade design pattern in C# in this article!
This article is not set out to try and persuade you, the reader, that either using an iterator or materialized collection will universally solve your problems. Both iterator and materialized collection usage can be used to solve the scenarios that we'll be looking at, but both will come with a different set of pros and cons that we can further explore. The purpose of this article is to highlight scenarios based on real world experiences where either an iterator or materialized collection was being misunderstood, misused, and ultimately leading to a pile of headaches. As you read this article, if you find yourself saying "Well, sure, but they should have..." you're probably right. The problem is fundamentally not the usage of an iterator or the materialized collection, but not understanding how to consume them effectively. So I hope that when…
Dealing with async EventHandlers in C# can be very problematic. async void is a pattern cause headaches with exceptions. Check out this simple solution!
If you're building a 2D game in Unity3D, odds are you've come across the TileMap component. The TileMap is a powerful tool that allows you to create a grid of tiles that you can render your tiles with instead of hand-placing individual game objects with sprites. It has a host of built in functionality that you might otherwise find yourself manually writing, like mapping coordinates to particular cells on a map. And what's even cooler about using a TileMap? You don't need to handroll your own editor to paint tiles! I think I'd pass on having to do that. But have you found yourself in a situation where you want to get all of the painted tiles on a TileMap? You may have found it's not quite as obvious as you'd have hoped! What We Have To Work With On…
I love dependency injection frameworks ever since I started using them. Specifically, I'm obsessed with using Autofac and I have a hard time developing applications unless I can use a solid DI framework like Autofac! I've recently been working with Xamarin and found that I wanted to use dependency injection, but some of the framework doesn't support this well out of the box. I' was adamant to get something going though, so I wanted to show you my way to make this work. Disclaimer: In its current state, this is certainly a bit of a hack. I'll explain why I've taken this approach though! In your Android projects for Xamarin, any class that inherits from Activity is responsible for being created by the framework. This means where we'd usually have the luxury of passing in dependencies via a constructor and…
Are you interested in learning about interfaces in C#? This article explains the idea behind a C# interface by showing examples of interfaces in code.
A few months ago I wrote up an article on using PyTools, Visual Studio, and Python all together. I received some much appreciated positive feedback for it, but really for me it was about exploring. I had dabbled with Python a few years back and hadn't really touched it much since. I spend the bulk of my programming time in Visual Studio, so it was a great opportunity to try and bridge that gap when looking at something like IronPython. I had an individual contact me via the Dev Leader Facebook group that had come across my original article. However, he wanted a little bit more out of it. Since I had my initial exploring out of the way, I figured it was probably worth trying to come up with a semi-useful example. I could get two birds with one…
Background: Lambdas and Why This Example is Important Based on your experience in C# or other programming languages, you may or may not be familiar with what a lambda is. If the word "Lambda" is new and scary to you, don't worry. Hopefully after reading this you'll have a better idea of how you can use them. My definition of a lambda expression is a function that you can define in local scope to pass as an argument provided it meets the delegate signature. It's probably pretty obvious to you that you can pass in object references and value types into all kinds of functions... But what about passing in a whole function as an argument? And what if you just want to declare a simple anonymous method right when you want to provide it to a function? Lambdas. So…
