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!

Unity Script Performance Testing

Tags: , , ,

Today’s article is the first to test Unity script performance speed. It establishes a way to set up and test C# scripts in Unity whether you have access to Pro or not. As a first example, I was reminded by the news this week that AddComponent(string) is being removed in Unity 5.0. These alternative versions of AddComponent and GetComponent aren’t something I normally use, but the news got me thinking of their performance compared to the generic-typed versions: GetComponent<ComponentType>(). The docs say to avoid the versions taking a string, but how bad could the performance really be? Today’s article puts the two versions to the test to find out just that!

Should You Bother Giving Variables a Type?

Tags: , , ,

Many modern strongly-typed languages have introduced a way for you to not have to type a variable’s type. In C#, you can use var instead of the actual type. In C++, you use auto. AS3 has a similar feature with it’s “untyped” type: *. In those other languages, var and auto are syntax sugar that the compiler replaces with the actual type. Will the AS3 compiler and/or Flash Player do the same for us? Today’s article finds out if it’s safe to skip the type and just use *.

Explicit Type Conversion

Tags: , , , , , , ,

Five months ago I said I’d talked about explicit type conversion. I hadn’t, really. What I talked about before was type casts. A cast changes the type, not the data. Today, I’m actually going to talk about type conversion and show you the costs of converting between all of your favorite types: int, uint, Number, Boolean, String, and even XML.

Implicit Type Conversion

Tags: , , , , , ,

I’ve talked before about explicit type conversion and used the function-call style (Type(obj)) and the as keyword to accomplish the task. Today, I’m going to talk about implicit type conversion and use—as implicit would imply—no operators at all!
