Can we write condition in switch case in C#?

A switch statement allows a variable to be tested for equality against a list of values. Each value is called a case, and the variable being switched on is checked for each switch case.

if-else better for boolean values: If-else conditional branches are great for variable conditions that result into a boolean, whereas switch statements are great for fixed data values . Speed: A switch statement might prove to be faster than ifs provided number of cases are good.

The simple answer is No. You cant use it like that . Switch works with single expression.

Testing Multiple Conditions with Switch and Case To begin, we will type the switch statement followed by the variable being tested inside parentheses as you can see in Fig. 3. Next, a series of case s control the execution flow based on the value of that variable.
