In swift, it is possible to toggle a Boolean by simply calling .toggle() on the var. var isVisible = false isVisible.toggle() // true I wanted to create the same functionality in C#, so I wrote an extension method on ‘bool’ public static class Utilities { public static void Toggle(this bool variable) { variable = !variable;… Read More Is it possible to alter a bool value by calling an extension method on the same variable in c#?

I’m trying to make extension methods for generic array, so I could takeout random set of elements. I made following extension methods for List<T> type and they work great, but I can’t work out how to do exactly the same for generic array: public static T Random<T>(this List<T> list) { return list[GameManager.instance.functions.RandomInt(list.Count – 1)]; }… Read More c# extension methods for generic array
