switch statements and expressions are useful when there are many different cases depending on the value of the same expression.
When a switch statement or expression is simple enough, the code will be more readable with a single if,
if-else or ternary conditional operator.
Noncompliant code example
switch (variable)
{
case 0:
doSomething();
break;
default:
doSomethingElse();
break;
}
var foo = variable switch
{
0 => doSomething(),
_ => doSomethingElse(),
}
Compliant solution
if (variable == 0)
{
doSomething();
}
else
{
doSomethingElse();
}
var foo = variable == 0
? doSomething()
: doSomethingElse();
