C# If Else Shorthand with Examples

C# Question Mark Operator

C# has a shortened version of an if else command. The use of it is very easy, if you understand it once

Notice:

The condition must evaluate to true or false. If condition is true, first_expression is evaluated and becomes the result. If condition is false, second_expression is evaluated and becomes the result. Only one of the two expressions is evaluated.


condition ? first_expression : second_expression;

condition ? first_expression : second_expression;

Example 1: The greatest number amoung two numbers


        Random rnd = new Random();
        var rand1 = rnd.Next();
        var rand2 = rnd.Next();

        var greater = rand1 > rand2 ? rand1 : rand2;
        Console.WriteLine(" Number 1:{0} \n Number 2:{1} \n The greatest number amoung two numbers {2}",rand1,rand2,greater);

        Console.ReadLine();

Random rnd = new Random();

var rand1 = rnd.Next();

var rand2 = rnd.Next();

var greater = rand1 > rand2 ? rand1 : rand2;

Console.WriteLine(" Number 1:{0} \n Number 2:{1} \n The greatest number amoung two numbers {2}",rand1,rand2,greater);

Console.ReadLine();

Example 2:(Alternative solution)


        Random rnd = new Random();
        var randomNumber = rnd.Next();

        var result = randomNumber % 2 == 0 ? "even" : "odd";
        Console.WriteLine("{0} is an {1} number. ", randomNumber, result);

        Console.ReadLine();

Random rnd = new Random();

var randomNumber = rnd.Next();

var result = randomNumber % 2 == 0 ? "even" : "odd";

Console.WriteLine("{0} is an {1} number. ", randomNumber, result);

Console.ReadLine();
