C# If Else Statement

The C# If else control statement has two blocks. One is true block another one if false block.

In case condition in if block is true, the statements in if block executed, if it is false, the else block statements executed.

The syntax of the C# if else is

if <condition>
{
   Statements //These statements are executed if the condition is true
}
else
{
   Statements //These statements are executed if the condition is false
}

C# If Else Statement Example

Let us see an example on if else by finding whether the given input number is even or odd?

using System;

namespace CSharp_Tutorial
{
    class Program
    {
        static void Main()
        {
            Console.WriteLine("Please enter any Numeric Value  ");
            int i = int.Parse(Console.ReadLine());

            if (i % 2 == 0)
            {
                Console.WriteLine("{0} is even number", i);
            }
            else
            {
                Console.WriteLine("{0} is odd number", i);
            }
        }
    }
}

OUTPUT

In the above C# code, we have taken integer variable i

Since Console.ReadLine() returns a string, and we explicitly converted to an integer using Parse.int

The input number is given 93

Since 93%2 = 1 the output is

93 is odd number
