Moving Methods out of Classes

Tags: , ,

In today’s article I’ll share a technique that can help you reason about your classes (and structs). The core idea is to move some methods out of the class into helper functions. Doing this can really simplify the class and simplify the functions so they’re much more easily understood by readers (including yourself!), more easily written, and more easily extended. Read on to learn more about this technique!

Making Enums More Flexible and Extensible

Tags: , ,

Enums are great at what they do: creating a simple integer type with specific values. Their main purpose is to choose one value out of many like enum Color { Red, Green, Blue }. But what if you have data attached to those choices? What if the data is one type for one choice and another type for another choice? What if there are two pieces of data to attach to one choice and only one for another? Today’s article shows a simple pattern you can use instead of enum in these cases to get a lot more flexibility and extensibility. Read on to see how!

Using Structs to Avoid Creating Garbage

Tags: , , ,

It’s easy to forget about struct in C#. After all, it’s not available in other languages like Java or AS3 and it seems to have fewer features than good old class. But struct can really help you out when it comes to garbage creation! Today’s article discusses some strategies to get the most out of struct. Read on to learn how to use structs to put a stop to that pesky garbage collector!

How to Recover Anonymous Types

Tags: , , , ,

When we just need a quick and dirty type to hold some values, C#’s anonymous types fit the bill: var person = { First="John", Last="Doe", Age=42 }. On the down side, since these types are anonymous they have no explicit type. The var variable is strongly typed, but you have to use the object type when passing them to other functions. But then how do you get the fields back out? Today’s article shows you how so that anonymous types will be more useful to you. Read on to find out how to recover anonymous types!
