If Statement

Stryg for at vise menuen

An if statement, also known as conditional statement, is a method of executing a block of code based on a condition. The syntax of an if statement is the following:

if(condition) {
    // code to execute
}

It takes an expression and executes the code block if the expression is true.

S3C5

For example:

main.cs

main.cs


              
12345678910111213141516

            
using System;

namespace ConsoleApp
{
    internal class Program
    {
        static void Main(string[] args)
        {
			Console.WriteLine("Before Conditional");
			if(10 > 9) {
    			Console.WriteLine("10 is greater than 9");
			}
			Console.WriteLine("After Conditional");
        }
    }
}

In case the condition is false the code block is ignored:

main.cs

main.cs


              
12345678910111213141516

            
using System;

namespace ConsoleApp
{
    internal class Program
    {
        static void Main(string[] args)
        {
			Console.WriteLine("Before Conditional");
			if(10 > 10) {
    			Console.WriteLine("10 is greater than 9");
			}
			Console.WriteLine("After Conditional");
        }
    }
}
