#46 Exception Handling Mechnaism

C# Provides try,catch and finally mechanism to handle Exception.

try: Business logic code block,potentially might cause exception 

catch: Block where all your exceptions are caught.

Finally:Block which always executes after try/catch irrespective of exceptions.( P.S: Stackoverflow will make the finally block not to execute)

Rules:

1.There must be finally block after try,If you do not have a catch block.

2.There can be two or more catch blocks.

3.Ordering of Catching Exception Matters.

4.Exception is the base of all other ExceptionClasses.

 try
 {
 /*your code here*/
 }
 catch(Exception exception)
 {
 /* Exeption caught if something goes wrong*/
 }
 finally
 {
 /*Guaranteed to run even if exception occurs.This block will always run*/
 Console.WriteLine();
 /*
 * Clean UP Code.
 */
 }
