C# 7 provides a very powerful feature from the performance standpoint. This feature is returning by ref. Essentially this allows for value types to be returned without having to copy them. The guidelines are normally that you shouldn’t use a struct with too many fields. Various sources quote various size guidelines. Whenever the struct was over the prescribed size it was recommended that you pass it by reference. With the new syntax for… Read More

I’m not really sure why Microsoft have never bothere with implementing a Fraction primitive in .NET. I’m sure there are plenty of uses as fraction allow to preserve the maximum possible precision. I have therefore decided to create my own implementation (albeit somewhat primitive at this stage) . My implementation automatically simplifies the fraction, so if you we to create new Function(6, 3) that would be simplified to 2. The Fraction struct implements… Read More

When implementing you own struct you should take into consideration the following: Use structs when you intend to create a great many of them structs should be small. Large structs (i.e. structs with many fields) would lead to poor performance, since structs are copied each time. Use structs when you require high density memory collections.  Structs have have a much simpler memory layout and offer excellent memory density and lack of overhead… Read More
