Question

What are ways of eliminating the use of switch statements in code?

Answer 1

Switch-statements are not an antipattern per se, but if you’re coding object oriented you should consider if the use of a switch is better solved with polymorphism instead of using a switch statement.

With polymorphism, this:

foreach (var animal in zoo) {     switch (typeof(animal)) {         case "dog":             echo animal.bark();             break;          case "cat":             echo animal.meow();             break;     } } 

becomes this:

foreach (var animal in zoo) {     echo animal.speak(); }
