How will you suppress error Message in Try catch block ?

Yeah, interviewers tend to irritate me.

Sometimes they don't know what they're talking about as they're not programmers themselves, or they're trying to catch you out with some trick question that has an obscure answer which no-one would even dream of using in practice!

 Now days most of the people ask this question to candidates.

 Suppress means how to avoid system generated errors and show user defined error messages.

 For example, this not accurate but will give you an idea:

 static void Main(string[] args)       {            
           try
           {
               int x = 1;
               int y = 0;
               int z = x / y;
           }
           catch (Exception)
           {
               CatchErrors err = new CatchErrors();
               //Console.WriteLine(err.Message);
               Console.WriteLine(err.ShowErrors());
               Console.ReadLine();
           }
       }

 public class CatchErrors : Exception
 {
   public CatchErrors() { }


   public void GetErrors()
   {
       throw new Exception();
   }
   public string ShowErrors()
   {
       return "Hello, You can't catch me out with that one!";
   }
 }

Well the idea is that, if an error occurs in the 'try' block, then the exception is caught in the 'catch' block. This then enables you to do something about it without the application blowing up. For example:

try

{

   int x = 1;

   int y = 0;

   int z  = x/y;

}

catch (DivideByZeroException)

{

   MessageBox.Show("You can't catch me out with that one!");

}
