C# if-else Statement :

if Statement :

The main format of the conditional statements if is as follows:

Syntax :

if (Boolean expression)
{
Body of the conditional statement;
}


The Boolean expression can be a Boolean variable or Boolean logical expression. Boolean expressions cannot be integer (unlike other programming languages like C and C++).

The body of the statement is the part locked between the curly brackets ( { } ). It may consist of one or more operations (statements). When there are several operations, we have a complex block operator.

Example :

  1. /* Description: simple if program */
  2. using System;
  3. namespace DemoProgramming
  4. {
  5. class Program
  6. {
  7. static void Main(string[] args)
  8. {
  9. int myNumber = 5, OtherNumber = 4;
  10. if (myNumber == OtherNumber)
  11. {
  12. Console.WriteLine("This is same number.");
  13. }
  14. //Black Screen Cause The Condition is not true (5==4)
  15. Console.ReadKey();
  16. }
  17. }
  18. }

if-else Statement :

In C#, as in most of the programming languages there is a conditional statement with else clause: the if-else statement. Its format is the following:

Syntax :

if (Boolean expression)
{
Body of the conditional statement;
}
else
{
Body of the else statement;
}

Example :

  1. /* Description: simple if-else program */
  2. using System;
  3. namespace DemoProgramming
  4. {
  5. class Program
  6. {
  7. static void Main(string[] args)
  8. {
  9. int myNumber = 5;
  10. if (myNumber == 5)
  11. {
  12. Console.WriteLine("This is same number.");
  13. }
  14. else
  15. {
  16. Console.WriteLine("This is not same number.");
  17. }
  18. Console.ReadKey();
  19. }
  20. }
  21. }

Output :

C Sharp Language simple if-else program
