# How do we use nested if statements in C#?

CsharpProgrammingServer Side Programming

Use one if or else if statement inside another if or else if statement(s). The syntax for a nested if statement is as follows −

if( boolean_expression 1) {
/* Executes when the boolean expression 1 is true */
if(boolean_expression 2) {
/* Executes when the boolean expression 2 is true */
}
}

The following is an example showing the usage of nested if statements in C#. Here, we have two if statement that checks two conditions.

if (a == 5) {
/* if condition is true then check the following */
if (b == 10) {
/* if condition is true then print the following */
Console.WriteLine("Value of a is 5 and b is 10");
}
}

Here is the complete example.

## Example

Live Demo

using System;
namespace Demo {
class Program {
static void Main(string[] args) {
//* local variable definition */
int a = 5;
int b = 10;
/* check the boolean condition */
if (a == 5) {
/* if condition is true then check the following */
if (b == 10) {
/* if condition is true then print the following */
Console.WriteLine("Value of a is 5 and b is 10");
}
}
Console.WriteLine("Exact value of a is : {0}", a);
Console.WriteLine("Exact value of b is : {0}", b);
}
Value of a is 5 and b is 10
Exact value of b is : 10
