Just like If statements, C# Ternary operator tests a condition and initializes a variable with the result of the condition.
C# Ternary Operator Syntax
<condition> ? <expression1> : <otherwise expression 2>;
If the condition is satisfied Ternary operator returns expression 1; otherwise, it returns expression 2. Let us see an example using a C# Conditional operator.
Example C# code using If else statement
using System;
class Ternary_Operators
{
static void Main()
{
int number = 15;
bool Isnumber15;
if(number == 15)
{
Isnumber15 = true;
}
else
{
Isnumber15 = false;
}
Console.WriteLine("Number == 15 is {0}", Isnumber15);
}
}
OUTPUT
ANALYSIS
Here, number is an integer variable initialized with 15. Isnumber15 is a Boolean variable to store the result.
I was checking whether number == 15 using if condition. If the condition is satisfied, then Isnumber returns true else Isnumber returns false.
Here, Isnumber = true printed on to the C# console.
C# Ternary Operator Example
It is the same example that we specified in the above. However, this time, we are using the C# Ternary operator. The ternary operator returns the result of the statement, and it will not execute the statement.
It returns the value of any data type.
C# code using Conditional operator
using System;
class Ternary_Operators
{
static void Main()
{
int number = 15;
bool Isnumber15 = number == 15 ? true : false;
Console.WriteLine("Number == 15 is {0}", Isnumber15);
}
}
OUTPUT
ANALYSIS
Using the ternary operator reduces the size of the code too much smaller.
In the above c# conditional operator code, we have collected the result of a statement into a boolean variable Isnumber 15. And the result is printed.
Instead of collecting into a variable, we can even directly print i.e., in the above code
bool Isnumber15 = number == 15 ? true : false; Console.WriteLine(“Number == 15 is”, Isnumber15);
Instead of writing in two lines, we can write as follows:
Console.WriteLine(number == 15 ? true : false);
