Ternary operator C# example-Learn how to compare two values using ternary operator (? : ) and how to execute the statement with explanation and example programs.
When ever we want to compare 2 values, we can do with the if else statement as shown below.
if(a>b)
{
Console.WriteLine("A is greater than B");
}
else
{
Console.WriteLine("B is greater than A");
}
In the same way whenever we want to compare 2 values, we can also do with a special decision making operator called ternary operator i.e (? : ) which is similar to if-else.
string output = A>B?"A is greater than B":"B is greater than A";Syntax:
data_type Output_Variable=condition? statementnt1 : statement2;Condition is the boolean expression.
statement1 is evaluated if condition is true and statement2 is evaluated if condition is false.
C# Ternary Operator Example
c# code
/*---------------------------------------------
* IF Else and Ternary operator example in C#
*/
public class ToStringExample
{
public static void Main(String[] args) {
int a = 5, b = 10;
String result;
/*---------------------------------------------
* Using IF then Else example
*/
if (a < b) {
result = " a is less than b";
} else {
result = " a is greater than b";
}
Console.WriteLine("result using if else condition : " + result);
/*---------------------------------------------
* Using Ternary operator example
*/
result = a < b ? " a is less than b" : " a is greater than b";
Console.WriteLine("result using ternary operator : " + result);
}
}
Output:
result using if else condition : a is less than b
result using ternary operator : a is less than b
NOTE:
Ternary operator makes the code shorter. There is no performance difference between Ternary operator and if – else.
use ternary operator only if the code is one liner and no change in the code in future. other wise use if -else.
