Why is this an issue?
The default
clause should take appropriate action. Having an empty default
is a waste of keystrokes.
Noncompliant code example
enum Fruit
{
Apple,
Orange,
Banana
}
void PrintName(Fruit fruit)
{
switch(fruit)
{
case Fruit.Apple:
Console.WriteLine("apple");
break;
default: //Noncompliant
break;
}
}
Compliant solution
enum Fruit
{
Apple,
Orange,
Banana
}
void PrintName(Fruit fruit)
{
switch(fruit)
{
case Fruit.Apple:
Console.WriteLine("apple");
break;
default:
throw new NotSupportedException();
}
}
or
void PrintName(Fruit fruit)
{
switch(fruit)
{
case Fruit.Apple:
Console.WriteLine("apple");
break;
}
}
Exceptions
default
clauses containing only a comment are ignored with the assumption that they are empty on purpose and the comment documents
why.
