We’ve seen how to create powerful, Burst-compatible generic algorithms already, but today we’ll take another approach to generic algorithms and implement them in the style of C#’s LINQ. Along the way, we’ll tackle a new challenge by implementing a generic algorithm that allocates a new collection.

Collection types like
Dictionary<TKey, TValue> are fundamental tools in C#. Sadly, I keep seeing the same misuses of them in codebase after codebase. Today we’ll look at the top 5 problems and learn how to easily avoid them!
It’s been over three years since the last article on LINQ performance. That was all the way back in the Unity 5.0 days using Mono as a scripting backend. Today we’ll update that article’s test with Unity 2018.1 and IL2CPP to see how LINQ fares these days. Is it any better? Read on to find out!
One of C#’s most unique features is its SQL-style LINQ syntax. It’s a powerful and expressive way to treat data structures like a database and perform all kinds of actions on them. LINQ can also be used without the SQL-style syntax via various extension methods of
IEnumerable<T> defined in the
System.Linq namespace. Due to C#’s extension method feature, we’re free to add on our own LINQ-style functions to extend its power. Today’s article introduces some extension methods to do just that. Read on for the source code and power up your LINQ!
LINQ expressions aren’t the same thing as LINQ queries. They’re more like reflection for the syntax of C# itself. It’s a fascinating—and powerful—area of the language and I’ll be exploring it a little in today’s article.
SQL-style LINQ queries are a concise, readable way of performing various tasks dealing with all kinds of collections. Surely all that convenience comes with a performance cost to it. How bad do you think it is? Today we’ll look at the cost of some basic LINQ queries (
Select) versus the equivalent non-LINQ code. We’ll also see how much slower both of them are compared to manually-written, traditional code that does away with all the flexibility. Read on to see the results!
