The if statement is one of the most important statement in almost all programming languages and in C#.
The main use of it is to specify an action to do but only when a condition of type bool is true.
For example lets make a simple console application that asks the user for an integer number and determines if the number given is an even number or an odd number.
static void Main(string[] args)
{
Console.Write("Enter a number: ");//asking the user to enter a number
int number = int.Parse(Console.ReadLine());//reading the given number
if (number % 2 == 0)//if 'number' is a multiple of two
Console.WriteLine("It's an even number");//Writing the result
else //this means "if not, do the following.."
Console.WriteLine("It's an odd number");//Writing the result
Console.Read();
}
