“Use of unassigned local variable” compiler error for switch statement in C#?

Question

I have the following C# code:

AnimalTypeEnum animal;
string s = Console.ReadLine();
switch (s.ToLower())
{
case \"dog\":
    animal = AnimalTypeEnum.DOG;
            


        

Answer 1

In case s.ToLower() is something else that dog, cat or rabbit, animal has no value.

You should add default in your switch for that case:

switch (s.ToLower())
{
case "dog":
    animal = AnimalTypeEnum.DOG;
    break;
case "cat":
    animal = AnimalTypeEnum.CAT;
    break;
case "rabbit":
    animal = AnimalTypeEnum.RABBIT;
    break;
default:
    animal = ...
    break;
}
