What is ternary operator in C#?

CsharpProgrammingServer Side Programming

Ternary operator is a Conditional operator in C#. It takes three arguments and evaluates a Boolean expression.

For example −

y = (z == 1) ? 100 : 180;

Above, if the first operand evaluates to true (1), the second operand is evaluated. If the first operand evaluates to false (0), the third operand is evaluated.

The following is an example −

Example

using System;

namespace Demo {

class Program {

static void Main(string[] args) {

int x, y;
x = 25;
y = (x == 25) ? 20 : 30;
Console.WriteLine("Value of x = {0}", y);

y = (x == 1) ? 50 : 90;
Console.WriteLine("Value of y = {0}", y);

}
y = (x == 25) ? 20 : 30;
y = (x == 1) ? 50 : 90;
