C# - Nested if Statements
It is always legal in C# to nest if-else statements, which means you can use one if or else if statement inside another if or else if statement(s).
Syntax
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 */ } }
You can nest else if...else in the similar way as you have nested if statement.
Example
using System; namespace DecisionMaking { class Program { static void Main(string[] args) { //* local variable definition */ int a = 100; int b = 200; /* check the boolean condition */ if (a == 100) { /* if condition is true then check the following */ if (b == 200) { /* if condition is true then print the following */ Console.WriteLine("Value of a is 100 and b is 200"); } } Console.WriteLine("Exact value of a is : {0}", a); Console.WriteLine("Exact value of b is : {0}", b); Console.ReadLine(); } } }
When the above code is compiled and executed, it produces the following result −
Value of a is 100 and b is 200 Exact value of a is : 100 Exact value of b is : 200
