Handle an Exception using try-catch Implementation with generic catch block

//Program to handle an Exception using try-catch Implementation with generic catch block using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace CAExceptions {     class ClsException2     {         static void Main()         {             int a, b, c;             Console.WriteLine("Enter Any Two Numbers:-");             try             {                 a = Convert.ToInt32(Console.ReadLine());                 b = Convert.ToInt32(Console.ReadLine());                 c = a / b;                 Console.WriteLine("Quotient value is:-" + c);             }             catch             {                 Console.WriteLine("Error Occured");             }             finally             {                 Console.WriteLine("Code Executed");             }             Console.ReadLine();         }     } }

Result:- 

 

• In the above example there is no exception class used in catch block, so it is known as generic catch block
• But in the above example any kind of exception may occur same message will be displayed to the user cannot understand why error has occurred, to overcome this specific catch blocks are used
• Using specific catch blocks it is possible to know more information about the exceptions
